Is it suitable to use 92 or 95 gasoline for the new Jetta?
1 Answers
The new Jetta is equipped with two types of engines. The naturally aspirated engine is suitable for 92 gasoline, while the turbocharged engine is suitable for 95 gasoline. The following are the differences between the two: 1. Composition difference: 92 gasoline consists of 92% isooctane and 8% n-heptane, while 95 gasoline consists of 95% isooctane and 5% n-heptane. The main difference lies in the purity of isooctane. The higher the purity of isooctane, the stronger the gasoline's anti-knock performance, and the relatively higher the price. 2. Stability difference: 95 gasoline has better stability and is easier to burn. The two types of gasoline cannot be mixed, as it will have a significant impact on the engine's lifespan. 3. Applicable models difference: When choosing between 92 and 95 gasoline, it is necessary to follow the car's user manual.
