Hello A4 owners. I'm considering getting my own gas card, but I don't know which to choose from. My family's been using union76 = official fuel of nascar!, but I don't know how they differ from other companies. Please enlighten me! Thankies!

go away when I put some slower gas in. I don't see how high octane would make the engine ping, should be the other way around =\.
