What are you getting for mileage?

I found that driving like you're carrying eggs is a great start (thanks for the tip Riff). You might also run your tire pressure higher (I'm running 45 psi) and make sure you have a great tune up.

I started out getting about 13 mpg. After about a year of using Lucas fuel treatment, doing a tune up, doing two seafoam treatments, higher tire inflation, and a few oil changes, I'm up to about 16 mpg.

If you're looking for much better than 16 mpg combined city/highway you're going to be disappointed...
