What type of fuel should an Audi A4 use?
2 Answers
Audi A4 should use 95-octane gasoline. Here is an introduction about refueling the Audi A4: 1. If 95-octane gasoline is unavailable: In an emergency, you can use 91-octane regular gasoline. However, in this case, you should only drive at moderate engine speeds and under low engine load conditions. It is essential to refuel with premium gasoline as soon as possible. It is recommended to use 95-octane premium gasoline. If this grade is unavailable, you may use 91-octane standard gasoline, but engine power will be reduced. 2. Alternatives: 98-octane super premium unleaded or at least 95-octane premium unleaded gasoline. Using 95-octane or higher-grade gasoline will improve combustion in the engine cylinders, enhance performance, and reduce carbon deposits.
I've been driving an Audi A4 for several years and am quite particular about fuel choices. Generally speaking, most A4 models recommend using 95-octane unleaded gasoline, especially the mainstream models in the Chinese market, as clearly stated in the manual. If your car is a high-performance version like the S4, 98-octane gasoline might be more suitable, ensuring smoother engine operation and preventing knocking risks. Once, I mistakenly filled up with 92-octane fuel, resulting in reduced power and slight engine noise, but switching back to 95-octane quickly resolved the issue. For long-distance driving or hot weather conditions, using higher-octane fuel is more reliable, protecting engine longevity and avoiding costly repairs. Don't compromise quality for cheaper options, as it may harm long-term performance and prove more expensive in the long run.
