Tune up

[blacksambo]

Maybe one should consider changing out the oxygen sensors as a tune up? Or maybe, switching from standard to synthetic lubricants (yes, mileage increases are possible). And that means everything, including the transfer case etc.. Also, revising camber and toe-in for optimal mileage performance? Just some random thoughts. Hope it helps.

Has the timing belt ever been changed? Check/change that ASAP. Take it to a mechanic for your next oil change and they'll perform a free multi-point inspection to make sure there aren't any seals leaking.

That's my two cents.
