Hey everybody, i just got back from a weekend trip to Chicago. There and back i got awesome mileage, low 30's (in the gas-log). Out of a 1988 3.8L Buick Centur.. This got me thinking that without trying it got that good of mileage. If I had a mpg gauge I should be able to do better. The Buick does have OBDI.
So.. I am looking for some help/ guidance in either fabricating a gauge, or if there is some commercial that could be made to work. Thanks for the help.
