I've started on my baseline...

[dkruitz]

I've got an '86 Mazda B2000 pickup - 5 speed, 4 cylinder, 2 litre displacement. Bone stock looking and I just got it a few weeks ago. I've replaced the gas tank with a new one and got my first run through it getting 21mpg (+1.2% over EPA) mostly around town driving. I'm planning on getting two more tanks through it before I start with any aero mods. All I've done so far is add a vacuum gauge.

I should have done a base line with mine before i started .....

I started out with a vacuum gauge but found it to be a bit misleading. When I began using the Scangauge 2 I learned the what has benefited my MPG the most, drive in the highest gear possible at all times (with the exception of acceleration). You should be able to get past 30 mpg average if you keep at it. I have, and my engine is .4 liters larger!
