I'm not an engineer or mechanic. It is time for our the "skilled" posters to chip in on this information. [/font]

2005 AWD Escape Hybrid
Best tank trip MPG 39.02 (scangauge II) for 402 miles on I-70, 10.3 gallons used over mostly flat terrain.

You can do anything, if you have enough time and money.
I had only a little of each, but I still DOUBLED my MPG with about $12,000 and 4 hours of time, and very little effort.

I bought a used Insight!
