Real world mileage numbers

I can't even understand the charts. But apparently mine is good.

Excellent Popcorn... :B

I just had the 100,000 mile diesel tune-up on it, and it looks like fuel mileage has increased, although I've not filled the tank since I had tune up, I can tell its improved.

What is a Diesel tune up?

New plugs, rotor and condenser. ;)

Not sure all they did, but did something with engine to clean it out from oil gunk, oil and fuel filter, plugs, rotate tires, new front brakes (which is wonderful now ... didn't realize how sloppy they were before), checked everything over with a fine tooth comb, and gave me a "high five" I could tow another 100,000. Actually the truck has about 115, 000 on it right now. But they called "it" the 100,000 mile diesel make over! (I suppose if this were my car, it would be equivalent to the first 3000 mile oil change!) :)

"Plugs"? :h

Oil gunk :H
"Equivalent to the first 3000 mile oil change" maybe why the oil gunk :W

Did you have the coolant changed, the brake fluid changed, the tranny fluid changed, new serpentine belt, new radiator cap?
Those are things that should have been done at 100K

You paid for service but not sure what they did.......

Good to know that my 8.1L is more efficient towing than the 6.0L I could have had. Just wish I had gotten the 7.4L that is even more efficient!!! Sounds like it all came from a facebook poll. Not real scientific I guess. I'm not even sure that was entertaining and it certainly wasn't useful. I guess that the Honda Element is more fuel efficient than V8 trucks is probably true.

Yep that's why I got the 3500 with the 5.9l Cummins

Hard pulling and gets 25 mpg city/35 mpg on highway and 18 mpg towing my high sided flat wind sail of a 5vr.
No DPF, no DEF and bone stock

Rolling coal.....no sticking 'supercharge' needed

:B:B:B

If you change your gears to 3.73, you can expect a 2-11 mpg increase. Though you towing numbers might drop .0125 mpg. If you don't tow much, it might be worth it.

Drilling holes in the cat converter also helps with mpg.

Interesting read, but pretty useless for anything but entertainment....of course - other than the 5.9L Cummins being on top of the mpg charts :W

When I had a 80 mile each way commute I would easily get 21mpg hand calc over many tanks with my 98 RAM 2500 4x4 quad cab auto.

My 11 RAM gets 14+ on a 50 mile commute. The 11 is well over 1,000# heavier.

Still the 5.9 is very fuel efficient.

UHH ok thanks!

I consider magazines just entertainment anyway. Same with this forum. Good day.
