#MITOSFAKTA | Dealer vs Bengkel Spesialis : Mana yang Lebih Jujur? - Dokter Mobil Indonesia

Summary

This video tackles various automotive myths and facts, debunking common misconceptions about car maintenance, transmission types, and hybrid engines. It covers topics like the safety of using different transmission oils (GL4 vs GL5), the durability of CVT transmissions, and the impact of engine braking on automatic transmissions. The video also touches on the importance of proper maintenance for fire extinguishers (APARs), the challenges of using sports cars in daily traffic, and the complexities of remapping hybrid engines. It provides insightful advice to ensure optimal vehicle performance and longevity.

Takeaways

• 😀 Proper transmission oil specifications are crucial for your vehicle's performance. Using GL4 oil instead of GL5 may be acceptable in certain cases, but always check the manufacturer's guidelines.
• 😀 CVT transmissions are not necessarily prone to failure on steep inclines. Newer CVT technologies are designed to be more durable and efficient compared to older models.
• 😀 Fire extinguishers (APAR) should be checked regularly for expiration. Even if a fire extinguisher is old, it can be refilled at a local fire department rather than buying a new one.
• 😀 It is unlikely for a fire extinguisher to explode just from being exposed to sunlight, but it is important to check its expiry date and pressure regularly.
• 😀 If you mix grease with transmission oil, it may lead to performance issues. Always use the specified oil types and avoid unnecessary modifications.
• 😀 Dual-clutch transmissions are ideal for sports cars due to their quick gear shifts, but they come with high maintenance costs and are typically more expensive to repair.
• 😀 Hybrid engines can be remapped, but it's much more complex due to the differences in engine cycles (e.g., Atkinson cycle). Tuning requires expertise in managing both the engine and the electric motor system.
• 😀 Using engine braking in automatic transmissions (CVT or AT) may wear down the clutch faster than regular braking, leading to higher maintenance costs for parts like clutch or brake pads.
• 😀 Performance cars, especially sports cars, are not recommended for daily driving in cities with heavy traffic, as they are designed for optimal performance at higher speeds, not for stop-and-go traffic.
• 😀 It's essential to follow the manufacturer's maintenance guidelines and specifications to prevent unnecessary repairs or premature breakdowns. Dealers may sometimes offer advice that benefits them more than the car owner.

Q & A

Is it safe to use GL5 transmission oil instead of GL4 in a transmission?

It is generally safe to use GL5 oil if the specifications on the label allow for it, but it's important to always follow the manufacturer's recommended oil specifications to avoid potential transmission damage.

Can the oil in a transmission be mixed with grease to make it last longer?

No, mixing transmission oil with grease is not recommended. While grease may make the oil thicker, it will negatively affect the transmission's performance and could lead to failure due to increased friction.

Does frequent use of a CVT transmission on steep inclines cause it to fail quickly?

No, a CVT transmission is designed to be more efficient without a differential, and it is generally more durable on inclines compared to other transmission types. However, like all transmissions, excessive strain or improper maintenance can lead to failure.

Can a car's air conditioning system explode if it is exposed to sunlight for too long?

It is highly unlikely for an air conditioning unit to explode just from being exposed to sunlight. However, it is important to regularly inspect and maintain safety equipment like fire extinguishers, as exposure to extreme conditions or damage from accidents can lead to risks.

How often should an air conditioner be checked or serviced in a car?

The air conditioning system should be checked regularly, ideally once a year, to ensure it is in good working order. It is important to also check the expiration date of the fire extinguisher in the car, as outdated ones need to be replaced or recharged.

Is it true that manual transmissions are better for climbing steep inclines than automatic transmissions?

Yes, manual transmissions often perform better on steep inclines compared to automatic transmissions, particularly front-wheel drive vehicles. This is due to the mechanical advantages of manually controlling the vehicle's power and minimizing wheel slip.

Why are sports cars not recommended for daily use in hot climates like Indonesia?

Sports cars are designed for high-speed performance and require constant airflow to keep the engine and transmission cool. In stop-and-go traffic, like in hot climates, sports cars can overheat due to limited air circulation, which is not ideal for daily use.

How does using engine braking affect the lifespan of a vehicle's transmission?

Using engine braking, especially when shifting from 'D' to '3' in an automatic transmission, can cause additional wear on the transmission because it puts strain on the clutch components or CVT belt. This can lead to premature transmission failure if overused.

Is it true that dual-clutch transmissions are only used in sports cars due to their high maintenance costs?

While dual-clutch transmissions offer extremely fast gear shifts and are often used in sports cars, they are not exclusive to sports models. However, they are more expensive to repair or maintain due to their complex design and the high cost of replacement parts.

Can hybrid vehicle engines be remapped for performance improvements?

Yes, hybrid engines can technically be remapped, but it's more complicated than remapping a standard engine. The remapping of hybrid engines involves adjusting both the internal combustion engine and the electric motor to ensure they work in sync, making it a more intricate process.
