Kruilty, those are ASTOUNDING numbers. Forgive me for being only 90% convinced that it is real; I don't think you're lying it's just too unbelievable. But then, you really went above and beyond looking at your list of mods.

I'm curious about your driving methods because those are obviously make-or-break no matter what mods you do.

I couldn't get the link to work. Those are incredible numbers. I am assuming you were using extreme hyper milling techniques to get that kind of mileage? The grid heater isn't EPA stuff at all, its to help the truck start easier and warm up quicker. In warmer temps it won't run much if at all. For getting the best possible mileage I can see why you would get rid of it, it puts a heck of a load on the altenator which of course uses fuel.

Hey, my best tank of fuel is somewhere around 18 mpg with my Cummins. Maybe with a tail wind I could beat your record.;)

H o l y c o w ! ! :Wow1:

I've seen ONE documentary on extreme fuel mileage and the driving habits that it takes and I would fail MISERABLY!

Is this like coasting around curves, timing every traffic light, zero idle time?

I saw your link and my sincere condolences to your German Shepherd, Diesel. I've grown up with 3 different ones since I was young enough to remember. Great friends. Very sorry for your loss.

Edit: Just noticed that was last year but STILL.
