I'll try to dig out the paperwork aerohead sent me. I don't recall it being more than 5 or 10%. Check back tonight.

Don't expect quick fixes to get you much over 10% either. With something like an old F-150 you'll be lucky to break 20mpg without major mods. For only 250 miles, drive behind a semi. Look at my Rabbit gas log- from normal driving habits to a slipstreamed highway trip I added 12.5% MPG. In a truck that's 2mpg if you're lucky. Like $8 savings.

Let's say your time is worth only $10 an hour... is making something complicated really worth it?
He gave me a dollar. A blood-soaked dollar.
I cannot get the spot out but it's okay; It still works in the store
