In the past 10 days, discussions about car maintenance, especially the selection of continuously variable transmission (CVT) transmission oil, have become a hot topic. This article will combine the hot topics on the Internet to provide you with a detailed analysis of the oil usage guide for CVT gearboxes, and provide structured data for reference.

1. The Importance of CVT Transmission Oil Selection

What oil should be added to continuously variable speed transmission?

CVT transmissions are favored by consumers for their smooth driving experience and fuel economy, but incorrect oil selection may cause transmission damage. Data shows that about 35% of CVT gearbox failures are related to improper oil quality.

Oil typeApplicable modelsReplacement cycle
Original CVT oilMainly Japanese cars (Nissan, Toyota, etc.)40,000-60,000 kilometers
Synthetic CVT oilEuropean cars (Audi, BMW, etc.)60,000-80,000 kilometers
Universal CVT oilSome domestic models40,000 kilometers

2. Recent hot topics of discussion

1.Original oil vs. third-party oil debate: 62% of users in the automotive forum recommend using original oil, but 38% of users believe that third-party oil that meets standards is more cost-effective.

Brandmarket shareAverage price (yuan/L)
Shell28%120-150
Castrol22%130-160
Mobil19%140-180
Original oil31%150-220

3. Expert advice

1. Be sure to refer tovehicle manualSpecified oil specifications, different brands of CVT oil cannot be mixed

3. Newly launched CVT models in 2023 generally require higher standards of oil.

4. Common misunderstandings among users

Misunderstandingfacts
AT oil can replace CVT oilViscosity characteristics are completely different and absolutely prohibited
Lifelong maintenance-freeOil quality still needs to be checked regularly
The more expensive the betterNeed to match gearbox design parameters

5. New trends in CVT oil technology in 2023

1. Lower viscosity: new 0W-20 CVT oil begins to be used

2. Electrification compatibility: demand for special oil for hybrid vehicles increased by 35%

3. Nano-additive technology: claimed to extend gearbox life by 30%

Summary:Selecting CVT transmission oil requires comprehensive consideration of vehicle model, driving environment and oil certification standards. It is recommended to conduct professional testing every 2 years or 40,000 kilometers and replace deteriorated oil in a timely manner. With proper maintenance, your CVT transmission can stay in optimal condition and provide you with a smooth driving experience.
