What grade of gasoline should an Audi 1.8T use?
1 Answers
Audi 1.8T models all require at least 95 octane gasoline. Advantages of 95 octane gasoline: Using 95 octane gasoline can reduce the likelihood of engine knocking and slightly improve engine performance. Gasolines with different octane ratings have varying levels of octane; 95 octane gasoline has a higher octane rating than 92 octane, and 98 octane gasoline has a higher octane rating than 95 octane. Composition of 95 octane gasoline: 95 octane gasoline consists of 95% isooctane and 8% n-heptane. High-compression engines should use high-octane gasoline. Using low-octane gasoline in a high-compression engine can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power.
