I recently purchased a 2021 Audi A4 and I'm unsure what octane fuel to use. I want to make sure I'm using the correct fuel for optimal performance and fuel efficiency. Can anyone advise on the recommended octane rating?
ReplyUsing a lower octane fuel may cause engine knock and reduce overall performance. Stick with 91 octane for best results.
While higher octane fuels may be marketed as performance boosters, they do not provide any added benefits for a 2021 Audi A4. Stick with the recommended 91 octane.
