That’s it! From there, you can fill up that A6. Just make sure that, when you’re done, you wait a few seconds for the rest of the fuel to drip into your gas tank. Then, simply twist the gas cap back on in a clockwise motion, and pop the fuel door back in place. Easy peasy!
Keep in mind that Audi recommends using Unleaded Premium gasoline. It may be pricey, but going with a lesser grade could lead to engine trouble down the line. That wouldn’t be a great way to say “thank you” to your brother-in-law, would it?
Have fun driving that A6!
