Most car owners have heard of transmission oil, but not everyone understands its role and how to choose the right type to optimize power and protect the car.

Car transmission oil has 3 main functions: Reduce friction, save fuel; reduce wear, maintain viscosity to prolong life; optimize transmission power for smooth gear shifting and smooth operation. Some quality oils also protect cars from wear, oxidation, rust, keep the temperature in the gearbox lower than normal, and avoid fire when operating continuously in hot, high temperature conditions.

Changing transmission oil must be done properly to protect the car’s transmission system. Car owners should regularly monitor the oil condition with the dipstick. The dipstick turns dark brown, black or makes strange noises, which is a sign that the car’s transmission oil needs to be changed. Each manufacturer has different recommendations for oil change times, usually every 30,000-40,000 km for the car to run smoothly.

Choosing the right type of car transmission oil and operating it correctly is not simple for inexperienced car owners. The car should be replaced at a reputable service workshop with specialized technicians. The manual replacement method usually drains 50% of the old oil in the crankcase. Mixing old and new oil in the long term can leave residue, easily damaging the gearbox, leading to complicated and expensive repairs and replacements.

Recently, some garages in Hanoi, Da Nang and Ho Chi Minh City have invested in a professional transmission maintenance solution for cars with automatic transmissions, the Motul Evo circulating oil changer. This solution can replace almost all of the old oil in the crankcase and automatic torque converter in about 20 minutes.

Automatic transmissions often have high repair, maintenance and replacement costs due to their complex structure. Therefore, the transmission oil for this type of transmission must meet the composition and technical specifications recommended by the manufacturer, to ensure the requirements: Anti-foaming properties, low temperature fluidity, low viscosity index change…

With manual transmissions, the driver’s driving style greatly affects the durability of the gears as well as the lubricating oil effect. Therefore, using the right type of transmission oil will ensure the transmission operates with stable performance and smooth gear shifting.

As a brand with 167 years of experience in the high-quality lubricant industry, Motul has just launched 4 lines of automotive transmission oil products with specialized features, serving manual and automatic transmission vehicles.

Three products specifically for automatic transmission vehicles include: Motul ATF VI, ATF 1A and Dexron III. Of which, Motul ATF VI is a high-end line with 100% synthetic oil, low viscosity performance. ATF VI meets most of the standards of automatic transmission car manufacturers on the market. The remaining product lines such as ATF 1A, Dexron III have the advantage of minimizing gear shifting delay, anti-wear, protecting the gearbox when having to operate continuously in high temperatures.

For vehicles using manual transmission, HD-X 80W90 is the right choice thanks to Technosynthese technology, specially formulated for vehicle transmission mechanisms, differentials, and gear sets that bear medium to heavy loads. In addition, the product helps reduce noise in manual transmission systems, improve thermal stability and protect the gearbox in many temperature conditions.
