Volkswagen Passat B5 Discussion
I at least think my gas mileage is not so good. I have a 03 B5.5 Wgn, 1.8t, tip, stock except for K&N air filter, I put in the highest octane gas I can find in my area which is 92, I do 90% of my driving on the interstate about 50 miles per day and run about 70mph, but I am only getting about...
