56.5 cents a mile they pay. Fuel mileage definately helps, more money in my pocket. Throwing around LBZs, deleted 6.4s and LMMs, and 03-04.5 cummins now, all seem to get around 22 if done right with deletes and tunes. LML and 6.7 I'm still just wondering if I left it alone and just drove every day, would it be reliable or still present problems with emissions crap? The new ones are just so quiet and ride so nice.
Haha, I hear ya on that. I have a 6.7 that's my DD, 2013 with 30k on the clock. My work pays for my gas and I have a 15k lb 5th wheel (I only tow a couple times a year but still) so it works out pretty good.
Really, if you're looking at a 6.7 with 100k miles. It'll already be out of warranty, so why not just delete all the emissions crap? You'll see an increase and mileage and less headaches to deal with. as soon as I hit 100k that's what I plan on doing. I would now if work didn't pay for my gas, but since they do it's not worth voiding my warranty just for the power and reliability (reliability isn't as important since any issues that would arise are still covered)
That being said. I love my 6.7. It's perfect. I have virtually nothing I would change about it other than the obvious (more power, better gas mileage, etc) but you can say that about ANY truck, and even if I got 25mpg, I'd still prefer more lol. It's huge and feels like a truck, but it's quiet and on the highway with bumps it rides more like a suv or car.
My girlfriend and I drove from south Alabama to northwest Iowa over Christmas. 23-25 hours each way. We drove straight through, and were beyond comfortable.
If you get a higher mileage 100k. I'd look for one that is a one or two owner, not used for business or a TON of heavy towing. If you can get the maintenance records that's a huge plus as well. I have a feeling many people don't change their fuel filters as often as necessary and that's incredibly critical, the fuel filters are not overly cheap and need to be changed more often than most vehicles, which I have a feeling some people that do their own maintenance may get around. Or those that go to the dealer, may not want to pay for.
