I drive a 2005 LS V8. I don't have to drive very far. I drive like 4 miles to work. I figured the V8 would be ok re:gas Because I don't go far. I'm getting 15.5 mpg, I don't usually drive over 45mph. Is it just that this car does better when you drive highway miles? Or is there something I could do to make mileage better? Has 28.5k on it now
Thanks
