Hey all, I hear that exxon and BP gases should be avoided in our audis. I hear that chevron, conoco, and shell are the best. Is this true? Which one of the 3 should I use?

Also I was wondering about fuel system cleaners, fuel treatments and oil treatments. Which ones do you all use or know that are good?

One more thing... Are there any ways to get better gas mileage besides a K and N filter?

THANKS A LOT!

K & N filter and Bosch Plantinum +4 plugs...

I sometimes throw in STP fuel additive to clean the injectors
