Chucky can I ask a question and one suggestion? What trans do you have?
and join Slant6.org lots of great information on there, but do a search and read before posting. Now if you want to get 30 and better,join there.
If you have a 904 is a good trans but a OD will give you better gas mileage or change to a 4 speed A833 OD see what gear you have in the rear and get taller tires(height) once all that is done take it to get your speedo calibrated.
Then keep a log of how much gas you put in and the mileage that will tell you more than anything to improve mileage driving does help but you can get the same results driving 55-65 without getting run over.
