It's a joke man, it's a joke. And I thought it was pretty funny.

It doesn't hurt to get a Bible study going, does it. Oh well, Christians are hard to find these days.

While I find the numbers pretty incredible, he has been tweaking this setup for quite some time and giving reports which are reasonable. There really isn't much more that you can do on a 12V engine for efficiency. Then, he has made some large aerodynamic improvements, namely the air dam. Keep up the good work with the mileage mods.

im trying to give those prius's a run for there money while towing a few

I wonder if you are producing less atmospheric destroying emissions than your smaller prius brothers while paying $2 a gallon in taxes because diesel is considered evil by those who love money.

finally, someone else out there can believe me too. I'm pushing 28 mpg and I don't have the 8 speed.

Cdennyb,

What kind of mileage were you getting before your upgrades. I got 13 right off of the lot. I have 40000 miles on it now and I am seeing about 22.6 mpg right now. My truck is stock.

sad but true hence all the full jails in America

i got 27 from NC to Indiana empty and that was up and down mountains, its all in the foot. Oh and 15 quarts of used oil in the fuel tank starting out.

when i first got the truck in decmeber it was getting around 23 and it was boned stock except for the gear vendors.

Some people say that these engines need to be broken in. Looking back to when I first bought it, I would say that this is true. My engine was extremely "tight", for lack of a better word. I have a friend who bought a 2005 2500 a couple of months before me and he got better mileage right off of the lot. I would like to do a couple of things to my truck to give it a better appearance, make it more usable and improve fuel mileage while still promoting longevity. That seems to be a very delicate balance acording to many posters on this site. Still, 33 mpg is awesome.

You lie in Baltimore and live in Philadelphia, you should have said 42.5 miles per gallon.

My engine started out life in my driveway with 31000 on it. I drove it every day back and forth to work, about 266 miles RT. It was cheaper to drive than stay in a motel at the time. I was averaging about 18-20mpg and as I crossed the 75000 mile mark it got considerably better. In the course of about 2-3 months it went up to around 23-25 mpg and that's when I figued it was "broke in" enough and went to all synthetics and additives. I can squeeze it into the 26 mpg range (all freeway) if I watch the foot and the weather's right. (I get considerably better mileage in the cooler wet season vs. the hot summer.)

i havent tried all synthetics, i went through the math and figured it wasnt worth it. so far ive put over 10,000 miles on my truck since december

How many rpm do you turn when you are getting your best mileage? What kind of boost does that stage III wh1c put out at cruise?
