If you can beat the 33mpg I used to get on the highway, then do it. I could get 19mpg around town if I kept everything under control (namely, my foot). But, this was all in stock form, straight from the factory.

275-300 per tank too oxygen - I feel better now lol

City driving + lead foot is a bad combination in vancouver(hills)

My 94 M6 with 3.73 gears gets 20 around town and 29 on the highway. This car is my DD so I will do a couple of more boltons, but that's it. But all things considered, you can't beat the mileage here. And I have 182k on it.
When I changed the gearing I did seafoam the intake and put new injectors in. I guess doing these things offset the gearing.

When I went from 245's to 275's, I saw about a 0.5 mpg hit, you can see my numbers in my earlier post.
