What grade of gasoline does the A5 use?
1 Answers
Audi A5 uses 95-octane gasoline. Gasoline grade location: The correct gasoline grade is located on the inside of the fuel tank cover. The gasoline grade represents its anti-knock performance, and the type of gasoline used by different cars depends on the engine's compression ratio. Rules for using gasoline in cars: Cars cannot use gasoline with a lower grade than specified, but they are allowed to use gasoline with a higher grade than specified. If the engine uses gasoline with a lower grade than specified, knocking will occur. If gasoline with too low a grade is added, knocking sounds may be heard during driving, and the engine will shake noticeably. If gasoline with a higher grade is added, since the higher-grade gasoline does not have enough pressure in the cylinder, it cannot fully combust, and over time, carbon deposits will form.
