5 Common Misconceptions About Motor Oil

1. All oils are the same, as long as they are changed regularly.

This is one of the most common misconceptions. Each type of engine oil has different composition and technical standards, suitable for each specific type of engine and gearbox. Choosing the wrong type of oil, for example usingmotor oil instead of automatic transmission oil, can cause high friction, increase heat and damage transmission parts.

Advice: Always read the vehicle manufacturer's instructions carefully or consult a qualified technician before changing the oil.

2. The thicker the oil, the better.

Many people think that thicker oil will provide better engine protection. However, the viscosity must be suitable for engine technology and climate conditions. Oil that is too thick can make the engine difficult to start, reduce performance and increase fuel consumption – especially in tropical environments like Vietnam.

For example: Oil lines have viscosity such as5W-30, 10W-40are popular, but should be selected based on the manufacturer's recommendations.

3. Just change the engine oil, no need to worry about the transmission oil

Many users only care about engine oil and ignore gearbox oil - a part that is subject to complex friction and transmission.Automatic transmission, especially CVT, dual clutch (DCT), requires specialized oil, with anti-foaming, anti-oxidation and friction coefficient balancing capabilities.

Suggestions from Gartz: Gear oil lines such asATF G4, G6, 9G-HP, or CVT GoldAll are manufactured to OEM standards, ensuring optimal performance for modern automatic transmissions.

4. Synthetic oil is only for high-end cars

Synthetic oil has superior properties such as thermal stability, anti-evaporation, and extended oil change intervals. However, many people think that it is only suitable for luxury cars. In fact, full synthetic oil can be used for popular cars, especially useful when the car is operated frequently or in harsh conditions.

5. The more expensive the oil, the better.

Price does not necessarily reflect quality without compatibility. An expensive oil that is not compatible with your vehicle’s transmission or engine will do more harm than good. The most important thing is the technical standards (API, SAE, OEM…) and manufacturing technology.

Conclusion: Understand correctly – Choose correctly – Protect correctly

Using the right oil not only helps increase the life of the engine and gearbox but also saves a lot of maintenance costs. Don't let small misunderstandings become the cause of major damage.
