Q & A

What is the main purpose of the video by ChrisFix?

The main purpose of the video is to educate viewers on what type of fuel they should use in their cars, explaining why, and debunking common myths about different types of gasoline.

Why should you not use the wrong type of fuel in your car?

Using the wrong type of fuel can damage the engine, lead to poor fuel economy, and potentially cause issues like detonation or engine knock, which can be harmful to the vehicle.

What does the octane rating of gasoline indicate?

The octane rating indicates the fuel's resistance to detonation or engine knock. It does not indicate the energy content, burning temperature, speed, or cleanliness of the fuel.

Why do some vehicles require higher octane fuel?

Vehicles with turbocharged, supercharged engines, or high compression engines are more likely to experience detonation with lower octane fuel, hence they require higher octane fuel to prevent engine knock.

What is a knock sensor and how does it work?

A knock sensor is a device in fuel-injected cars that listens for engine knock. When it detects knock, it signals the car's computer to adjust the engine timing to prevent further knock, thus protecting the engine.

What is the difference between the octane ratings in America and Europe?

In America, the octane rating is based on the pond pump octane number, while in Europe, it's based on the research octane number. Despite the difference in naming, the actual octane levels are comparable, with Europe's 95 octane similar to America's 89 and 93 octane.

Why are fuel additives important in gasoline?

Fuel additives are important because they help keep the engine clean by preventing the buildup of carbon deposits, which can lead to reduced efficiency, poor fuel atomization, and potential engine damage.

How can you determine the correct fuel to use in your car?

You can determine the correct fuel by checking the manufacturer's recommendation, which can be found on a sticker behind the fuel door, on the fuel filler cap, in the owner's manual, or sometimes indicated on the dashboard.

What should you do if you accidentally fill your car with the wrong fuel type?

If you accidentally fill your car with the wrong fuel type, you can use an octane booster to raise the octane level of the fuel in the tank. It's also important to drive gently and allow the car's knock sensor to adjust the engine timing to prevent damage.

What does 'E85' mean and when should it be used?

'E85' means 85% ethanol and should only be used in flex fuel vehicles. It is not the same as 85 octane gasoline and using it in a non-flex fuel vehicle can cause engine damage.

Why might a car that normally uses regular fuel require premium fuel in certain situations?

A car that normally uses regular fuel might require premium fuel if it has significant carbon buildup, has been modified, or has been tuned to perform differently. Always follow the advice of a professional tuner or mechanic in such cases.

👍 Summary and Viewer Engagement Invitation

In conclusion, ChrisFix reiterates the importance of using the fuel recommended by the vehicle's manufacturer to ensure optimal performance and avoid detonation. He invites viewers to ask questions in the comments section if they have any doubts or need further clarification on topics covered or not covered in the video. The summary serves as a recap of the key points discussed and encourages viewer interaction for additional support.

Keywords

💡Octane

Octane refers to the measure of a fuel's ability to resist detonation or engine knock. In the context of the video, it is a critical factor in determining the appropriate fuel for a vehicle. The script clarifies that all gasoline octanes have the same energy content, but higher octane fuels are more resistant to detonation, which is crucial for engines with high compression or forced induction. The video uses the example of a Corvette to illustrate the need for higher octane fuel to prevent engine damage due to detonation.

💡Detonation

Detonation, also known as engine knock, occurs when the fuel-air mixture in an engine ignites abnormally, causing a rapid combustion that can damage engine components. The video explains that detonation can happen when a fuel with a lower octane than required is used, leading to uneven and explosive combustion. This is illustrated by the sound of 'metallic pinging noises' that can be heard when detonation occurs, indicating potential harm to the engine.

💡Fuel Economy

Fuel economy is the efficiency of a vehicle in terms of the distance it can travel with a certain amount of fuel. The video script debunks the myth that higher octane fuels provide better fuel economy due to more energy content. It is emphasized that all gasoline octanes have the same energy, and the choice of fuel should be based on the engine's octane requirement to prevent detonation, not for improved fuel economy.

💡Knock Sensor

A knock sensor is a device in modern cars that detects detonation or engine knock. As explained in the video, when a knock sensor detects abnormal combustion, it sends a signal to the car's computer to adjust the engine timing to prevent further knock. The video uses the knock sensor as an example of how modern vehicles attempt to self-correct when lower octane fuel is used, although it advises using the correct octane fuel to avoid knock in the first place.

💡Fuel Additives

Fuel additives are substances added to gasoline to improve its performance and quality. The video discusses how additives help clean carbon deposits, also known as 'gunk and sludge,' which can accumulate in the engine and reduce efficiency. It specifically mentions that Shell's premium fuel contains seven times more additives than legally required, highlighting the role of additives in maintaining engine cleanliness and performance.

💡Ethanol (E85)

E85 is a fuel blend containing 85% ethanol and is intended for flex-fuel vehicles. The video script clarifies that E85 does not refer to octane rating but to the ethanol content. It warns viewers to check their vehicle's compatibility with flex-fuel before using E85 to avoid engine damage, emphasizing the importance of using the correct fuel type for one's vehicle.

💡Manufacturer's Recommendation

The video strongly advises viewers to follow their vehicle manufacturer's recommendations regarding the type of fuel to use. It explains that manufacturers have specific requirements based on engine design and performance needs. The script provides methods to find these recommendations, such as checking the fuel door, fuel filler cap, or owner's manual, and stresses that using the recommended fuel is essential to prevent engine damage and ensure optimal performance.

💡Octane Booster

An octane booster is a product that can be added to regular gasoline to temporarily increase its octane level. The video mentions octane boosters as a solution if one accidentally fills up with regular gasoline in a car that requires premium fuel. It explains that adding a booster can help prevent engine damage by raising the octane level of the fuel, allowing the engine to run safely until the next fill-up with the correct fuel.

💡Compression Ratio

Compression ratio is the measure of the volume ratio of a fuel-air mixture in an engine's cylinder before and after compression. The video script explains that high compression engines are more prone to detonation, making higher octane fuel necessary to prevent engine knock. It suggests that carbon buildup over time can increase the compression ratio, potentially leading to detonation, which is why using the correct octane fuel is crucial for such engines.

💡Carbon Deposits

Carbon deposits are a byproduct of incomplete fuel combustion that can accumulate on engine components like valves, injectors, and pistons. The video illustrates how these deposits can reduce engine efficiency and power, leading to poor performance. It emphasizes the role of fuel additives in preventing and removing carbon deposits, maintaining engine cleanliness, and ensuring optimal vehicle performance.

Transcripts

Hey guys ChrisFix here and today i'm gonna show you what fuel you should use in your car and

not only am I gonna show you but I'm also gonna explain why so we could stop all the myths and misinformation out there about

different fuels so no matter what vehicle you drive whether it's a luxury car a truck or SUV a

Compact car a hybrid a sports car a convertible or a muscle car if it uses gasoline

This video applies to you

Now at the gas pump there are a bunch of choices that you can make you could use the less expensive

Regular gas you could use the mid grade or you could use the more expensive premium or super gasoline

So which one do you pick no one wants to put the wrong fuel in their car and damage the engine get poor fuel economy

Or spend extra on fuel. That isn't gonna help them

so in this video

I'm gonna show you exactly what gas your car should use and

Why and I want to thank shell for supporting this video and for letting me tie up one of their pumps so I could film

And teach you guys what fuel is best for your car and once and for all?

Stop all the myths and give you guys the facts. So with that said let's get started

Here's what you're gonna see when you're walking up to a pump in this case

We have diesel here

Which we're not going to talk about in this video if you have a diesel truck or car

Don't put gasoline in it because it won't run

It'll damage the engine and vice versa

If you have a gasoline car don't put diesel in it, so don't make that mistake

But we're not gonna talk about this. What we are going to talk about is the gasoline so in America we have

87 which is regular 89, which is mid grade and 91 or 93

Which is premium or high test fuel these octane numbers tell you one thing and one thing only the resistance the fuel has to

Detonation or engine knock and I want to clear up a myth right away that I hear all the time

And that is the bigger the number the more energy that fuel has so you're gonna get better fuel economy because it has more energy

Or you're gonna get more power because as more energy and that's completely false

so all the different Octane's of gasoline have the same exact energy content 87 89 91 93 all

Have the same energy in them now

There's some myths out there that say certain Octane's burn fuel hotter or colder or faster or slower

And that's just not true these all burn the same temperature at the same speed

There's other myths out there say certain octane fuels burn cleaner or more

completely and that is also not true a more complete burn has less to do with the actual gasoline and more to do with the

fuel to air ratio inside the combustion chamber

So the octane ratings that you see at the pump are exactly that the octane rating of that fuel

87 and 93 have identical energy content

but the octane in 93 is higher than the octane in 87 and that is

Important octane is the resistance to detonation or engine knock and detonation and engine. I could destroy an engine

So in turbocharged engines supercharged engines or high compression engines like in this Corvette

You're more likely to get detonation. If you're using a lower octane fuel with forced induction or high compression. There's more heat

there's more pressure and that means the fuel is more likely to explode before it's supposed to and that detonation that knocked sounds like a

Bunch of marbles or ball bearings bouncing around inside the engine making metallic pinging noises, which is not good

Let me show you why here's the combustion process inside of an engine

Now when you're using the correct octane fuel the spark ignites the fuel and the flame starts at the spark and travels outwards

This is a smooth and even burn that creates pressure to push the piston

Downwards and then the exhaust gasses are forced out of the cylinder and the process repeats

Now, let's take a look at the combustion process when you use a fuel with a lower octane than the manufacturer requires

So the fuel and air mixture is pulled into the combustion chamber and the spark plug ignites

It just like normal

But as the flame moves outwards the pressure inside the cylinder increases and causes pockets of fuel to ignite

unevenly and this creates an explosion rather than a smooth burn and that metallic naki here is the

uneven explosion which could damage the piston piston rings

Valves head gasket and even the block so higher octane fuel prevents detonation in forced induction and higher compression engines

Now today's fuel-injected cars have something called a knock sensor

The knock sensor is like a doctor's stethoscope except for your car's computer

It actually listens for engine knock and when it hears the engine knock it tries to

Change the timing of the engine to prevent knock but you don't want to have engine knock in the first place you want to fill

Up with the proper fuel. So you prevent engine knock altogether

So your decision at the pump is pretty important the higher the octane fuel the we're resistant to engine knock

But that doesn't mean when you pull up to the pump

You should run the highest octane you could get because you might be throwing money away many cars run perfectly fine unregular gasoline

And I'm gonna show you in a little bit how to tell which fuel your car should be using so you don't put premium in

A car that could use regular and vice versa. You don't want to put regular in a car that needs premium

So I'll show you that in a second

but first the next myth I want to bust and that I hear all the time is that fuel from America isn't as good as

Fuel from Europe or Australia or other parts of the world?

And the reason why people think this is because we have 87 octane 89 93

now if you look at a pump in Europe

You see 95 octane and 99 octane since 95 and 99 are bigger numbers than what you can find at American gas pumps

It must mean the fuel here has higher octane

And actually this is misleading because in Europe they use run research octane number as their rating for octane in America

We use pond pump octane number for our rating so fuel from Europe and fuel from America are basically the same

Europe's 95 octane is like our 89 or mid-grade Europe's 99 or 98 octane is like our

93 octane or premium

So hopefully that clears that myth up the fuel here in America is very similar to the fuel in Europe

The octane rating system is different, but the octane is the same or very similar

Alright, so now you know octane is the main difference between the different fuels and how important octane is

But there's one other thing I want to talk about and that is fuel additives. So every brand has to add a fuel additive

It's set by the government to keep your engine clean

Each brand has their own proprietary ingredients and they all do it in their own specific ways

Some of them use the exact same amount of additive in each of their fuels I know

Specifically for Shell they use seven times more additive than required by law in their premium fuel. Now. What does this additive do?

well

It helps clean carbon deposits also known as gunk and sludge

If you don't have these additives in the fuel over time

Your engine will become a lot less efficient so you could get carbon deposits in your fuel injectors

You could get it on your Pistons or on the piston rings, and you could get it on your valves now

I'm not the type of person to just tell you these things

I like to show examples so you could really understand

So I'll show you dirty fuel injectors on the fuel injector tester here

But first let's take a look at the difference between clean and dirty valves here are four four valves from a port injected

four-cylinder motor

This is a completely clean valve to give you a reference of what a clean valve looks like. And here's a good comparison

This is a valve with the normal amount of carbon deposits on it

This right here is what you would find in a normal daily driven port injected vehicle

You can see there's some carbon deposits on the valve where it seats against the head

There's some carbon deposits of right here and there's some carbon deposits on the valve stem but nothing

Significant also if we take a look underneath the valve you can see there's carbon deposits under here as well

and again

This gives you a good idea of what you would normally

Find and here's a good example of a valve that has some carbon deposits on it

This isn't even that bed direct inject engines could be much worse with carbon deposits

Building up on the top of the valve right here

Now the problem with this gunk and sludge is it's gonna lower the efficiency of your vehicle

So fuel isn't gonna atomized with the air as well the air traveling over this valve isn't gonna travel as smoothly into the combustion chamber

The valve might not seat properly

Against the head and not seal properly

So you'll lose fuel economy and you'll lose some power and that's why it's important to make sure your engine stays clean

So you're able to see the difference between clean and dirty valves now?

Let me show you the difference between clean and dirty fuel injectors using this fuel injector tester

so here are four fuel injectors and you could see injector one and four have a good even spray pattern but injector three is a

Little dirty and the spray pattern isn't as strong an injector two is by far the dirtiest and has a very poor spray pattern

Here's the queen injector

number one next to the dirty injector number two

And you can see the difference in spray pattern the clean injector atomizes the fuel and makes a fine

Mist whereas the dirty injector has more of a stream

It's not atomizing the fuel and that will cause poor fuel economy and a decrease in power

Because the fuel isn't gonna burn as evenly like in the rest of the cylinders

So if you have a slight misfire lower fuel economy a decrease in power

There's a potentially of a clogged injector like this

And this is where using a good high-quality

fuel could help clean the injector and restore the proper spray pattern and

I think that's so cool to be able to see the fuel injectors and how they spray now the last thing I want to show

You is the top of a piston now, I don't have any Pistons because they're hard to give an engine

So instead we're gonna go into the engine using a special borescope camera

And I'm going to show you what it looks like in there and how the carbon deposits form on the piston head

So I took the spark plugs out and I'm gonna slide the borescope camera into the spark plug hole so we could see the top

Of the piston and you can see the dark spots on the piston. I'll circle them in red

These are the carbon deposits now a little bit of carbon deposits is normal this right here what you see is completely normal

But if this builds up too much

You could increase the compression of the engine or create hot spots which both of those could cause detonation

So that's how fuel additives help keep the engine clean from valves to injectors to piston heads

But shells v-power Nitro+ does a couple of other things. I just want to mention real quickly because it's pretty impressive

So let's take a look inside of an engine to see what the fuel additive does more specifically

Let's look at what the piston is doing. It's important to prevent wear and tear inside of the engine

So it lasts a long time and that's not easy because inside of an engine there's a lot of fast moving

Parts that are undergoing some pretty tough conditions

The engine oil is the main protector of all these moving parts, but now this new fuel additive actually helps out a little bit

It'll get on the cylinder wall and help protect the upper piston rings against friction and wear so that's some pretty cool technology

And there's one more benefit. I want to mention

So if your car doesn't get used a lot, maybe only take her out on track days

Otherwise she's getting stored or maybe you store your car for the winter and doesn't get started

You want to make sure you protect your fuel system from corrosion like you see on this valve and this fuel additive will actually do

That it'll help protect the metals from corroding so they don't end up looking like this

So now, you know about octane, you know about the fuel additives, but what does this all mean for your car?

What fuel should you use for your car? The answer is very simple no matter what car you drive

Use the manufacturers recommendation on what fuel to use they design the car. They design the engine they design the tune

so if they're saying to use premium

Use premium if they're saying to use regular use regular and there's three different methods you could use to find out what fuel your car

Should use let me show you them the first and easiest method is when you go to fill up just check behind your fuel door

And look for this sticker you can see right there

It says use 91 octane or greater. If you don't have this sticker here check the fuel filler cap

Sometimes it's written on there but not every car

Has it written on the filler cap or on the back of the fuel door?

For example in the drift staying there is nothing written on the back of this fuel door. There's also nothing the fuel cap

So how do you know what fuel you should use in this car?

simple grab your owner's manual

Flip to the back you can see right here. It says fuel choosing the right fuel filling your vehicle with fuel

Let's go to those pages and there you go

I can see right away use 87 octane use regular it also gives you other good information like filling up in a higher elevation

If you hear light knocking or heavy knocking and fuel quality different things like that

So it's worth the read but I know not everybody has an owner's manual

So there's one more place that you could check and that is on the dashboard of your vehicle

So get inside your car and take a look on your dashboard

You want to check over by your fuel gauge? You could see on the gauge. It says premium required

So this is another place you could look now notice that said premium required

there's a big difference in language between the word required and recommended when talking about fuel this car needs premium it is

required

So if you put regular in it, it could damage the engine but some cars say premium recommended for example

If we take a look at my Corvette underneath the fuel door, it says right here premium recommended

So what that does is that allows us to run regular fuel without any issues

So the cars knock sensor will adjust the timing so you don't get that

Detonation and you could run regular with no problem at all

You'll lose a little bit of fuel economy and probably a little bit of power

It might not be noticeable, but it is completely fine and completely safe to run regular

But again, it says premium recommended not required and also it's recommended which means it is better to run premium

But you don't have to now there are a couple situations where your car is supposed to run regular

But you need to run premium. For example, my truck has a hundred and fifty thousand miles on her

I was driving on the highway one day giving it some gas and all of a sudden I was hearing detonation

so I immediately pulled off filled up with premium and that detonation went away when I think what happened was there's carbon buildup inside the

Engine either increasing the compression ratio, or maybe it created a hot spot in a cylinder either way

I was getting detonation with the premium it went away

so in that type of scenario

You definitely don't want detonation run premium and show claims if you run their premium fuel for 2,500 continuous miles

It'll clean 70 percent of the carbon deposits in the injectors

And if you have a port injected engine 70 percent from the valves, which is pretty impressive

So not are you stopping that detonation, but you're cleaning it out now I could run regular fuel without any issues

So the problem went away, which is a good thing another situation

Where my car normally takes regular this is the drifts thing

She could take regular all day long

But you might need to change the premium if you start modifying the car or get it tuned in this case

I haven't got it tuned yet

but when I add the

Supercharger and go to the tuner you have to listen to what your tuner says if your tuner says run 93

Make sure you run 93

Otherwise, you're gonna get detonation and you could damage your engine so stock she runs regular just fine

But once you get a car tuned listen to your tuner and the last scenario I could think of is your car requires premium

But for whatever reason you fill it up with regular, maybe you hit the wrong button by mistake

You hit the 87 and you fill your car up with regular you don't catch it

Or maybe you're at a gas station

And they don't have premium and you're in the middle of nowhere and you need to get gas

Otherwise you won't be able to get to where you need to go. Don't worry

There is a solution after you fill up with the regular gas

what you would do is you would go out and you would buy one of these bottles of

Octane booster and you could get this at your local parts store

sometimes the

supermarket maybe even the gas station you're at and all you do is you empty it into the gas tank and this will boost the

octane of that regular fuel that you put in there so you won't damage your engine and if you have to drive to pick this

Stuff up just take it easy

Don't give the car a lot of gas and go slow and then knock sensors on the engine should adjust the timing so you don't

Damage your engine and there's one more thing. I want to mention in that is

e85 if you see EA t5 like this this doesn't mean 85 octane this means

85% ethanol and you only want to use this if you have a flex fuel vehicle again

You could check your owners manual to see if your vehicle is flex fuel or not

But make sure you do that because if your vehicle isn't flex fuel

You could damage the engine by running

E85 and I just want to mention that really quick so you don't fill up with the wrong fuel by mistake

EA t5 is 85 percent ethanol not 85 octane

but if you have any questions at all about

Anything I showed in this video or anything

I didn't show that you might think of feel free to comment below and I'll answer them but in summary use the fuel your car

manufacturer recommends if they say run regular run regular if they say run mid grade run mid grade if

It says premium required run premium if it says premium recommend you could choose but for my experience

Premium will let the car run better. You'll get a little more power and a little better fuel economy

Plus you won't have to worry about any detonation at all

But it really is that simple just use what the manufacturer recommends. So, there you go

now

You know what fuel you should use in your car and why?

We busted a couple of myths and I told you guys the truth and all the facts

So you have all this knowledge on what fuel you should use
