Funny you mention that Matt, my mileage has increased around town after flogging my truck up that hill last weekend.
hahaha u sure it wasnt cause u were 15k lighter?? And i thought i was gonna have to do injectors. Funny thing is, i consider my 6.0 to be one of the reliable 6.0s. loll Only been in the shop twice in 120k.. Knock on wood
On and an update on the VSS, the CEL never came back up for that P0500 (VSS). So im not gonna change a thing
When you run engines hard shortly after new it helps to seat the rings and merry all the moving parts together. This contributes to better fuel mileage. Although, some on here have mentioned that there is a bit of a correlation to less fuel mileage on diesels after break-in due to the DPF getting worked in. I am not quite sure what to make of that... Though I am glad I got to give my engine a good hard run. I don't get to work it that hard on a regular basis so a good blow-out can be a good thing once in a while.
So i am comparing a 6.2L Gas and i have a 6.0L Diesel now. I pull 2 tractors (a total of 15,000lbs) to tractor pulls around the area, and my 6.0L did fine but not happy with the maintenance costs. Looking into a 6.2L gas. What do you think? Will she pull it?
I don't own a 6.2 (I still have my ancient V10 PI 2V) but if you look at the PDF I made in the post above you see that the 6.2 with 4.30's we tested was nearly has fast as the 6.7 PSD. We were towing 15K up a pretty good incline so it gives you a good idea what it can do. I have little doubt the 6.2 could hang with the 6.7 (high altitude where air is thinner comes to mind as a sure win for the 6.7) in many situations and it probably can outpace a 6.0 in many of them.
The 6.0 we tested is not a good indication of performance since it was having boost issues. Found out later the turbo was leaking pretty badly and on top of that it was also having VSS issues.
I was very impressed with the 6.2 that day. I was not a fan since Ford did away with my beloved V10 in the F250/F350 but I changed my tune after that day. If you were towing 15K every day and needed to make a living then the PSD would make more sense from a fuel mileage standpoint. However if you are towing 15K once in awhile I would not be afraid of getting a 6.2.
