Hi Han

You know what i do? I just drive my car the way they designed it -and not worry about milking the extra mpg. I then have lots of free time to get on with my life. I am certain half the PHDs on the planet are coming up with way better ideas on how to get more fuel efficient cars, and I prefer to wait until they do , instead of trying to milk an extra .045 cents per mile . How bout i drive it a little less and walk more? Ride a bike?

Thats the best suggestion i have ever heard on this site.

cheers
