one thing that helps a lot are the tires, rolling resistance needs to
be reduced. go with the thinnest tire you can fit on the rim and run it
with as much air as the tire can take and not wear it too severly, i've
had good luck running my tires at 40 psi, no abnormal wear and i drive
my na golf 520 miles a week back and forth to work, i've got 36k on
those tires and they still have good tread and no abnormal wear. those
185/65's are a semi performance tire meant for high grip, get the econo
box tires instead, the ride quality might suffer some, but it can help
the mileage a little.
