I just bought a 2021 Audi A7 and I'm not sure what is the best octane level to use for optimal performance. I don't want to use too low or too high of an octane level and risk damaging the engine. Can anyone provide some guidance?
ReplyThe recommended octane level for a 2021 Audi A7 is 91 or higher. Using a lower octane level can cause engine knocking and potentially damage the engine. Stick to the recommended octane level for the best performance and longevity of your engine.
