City Fuel Mileage?

bordin34 said

Thanks, to get better mileage I am thinking of getting a clutch fan, going to a lower weight oil, and putting synthetic rear end oil in.
I have 2.76 rearend gears I believe and a totally stock 74 318 with all the emission stuff connected.
If anybody has advice post it up.

The couple biggest gains for me are have the front end aligned properly and make sure the parts are all good, and air the tires up to 2-5lbs under their max pressure. Most tires are low on air anyway, and will always lose some over time (especially in warm/cold climates like the northeast). Most tire shops won't inflate beyond 32psi, but the tires generally have max pressures of 45psi. So I puff them up to 40 and watch the tread wear. If the center wears more, drop a couple psi. tire pressure makes a huge difference, and most cars could benefit from an alignment guy that actually knows how to properly set ride height and do an alignment consisting of more than setting toe.
