Audi advises using premium gasoline with an octane rating of 91 or above for your A6. Fuels with higher octane ratings combust more thoroughly in your engine, thereby enhancing the performance and responsiveness of your high-performance vehicle. Additionally, some available gasoline options are marked as top tier. These fuels contain detergents designed to clean and dissolve sludge, contributing to a longer-lasting and cleaner engine. I also suggest opting for these top tier fuels, as they can save you significant expenses on repairs and engine cleanouts should sludge accumulate from using cheaper fuels.
