Largecarman. You get a A+ for effort but your math is wrong. 100000mi for 30000$ works out to 33.33 cents per mile, not $3.40.

makes sense. but i do believe that in a regular pickup like a ford powerstroke/dodge cummins/gm duramax that these engines would long out last the trucks themselves to the point where the engines are good but the bodys are junk. i know with a cummins you want to go through it at about 350,000 or so. i wonder how many people that have one of these that use it for daily driving and towing on the weekend will actually hit 350,000 miles. maybe i am underestimating the life of the body on these trucks. but hopefully i will be able to pull 400,000 to 500,000 miles out of a cummins when i get one. but i dont know if i have the discipline to hold onto a truck for 25 years, or if the rest of the truck would be up to the task.
I don't know who told you that a Cummins diesel need to be overhauled at 350,000 miles. There are hundreds out there with over 1,000,000 miles on the engine with no problems with the block itself; and doing this on Shell Rotella T conventional oil. And the bodies are just fine.
on the dodge trucks? wow, didnt know that you could get that long out of one without opening up the engine.
What LACTD said.
Dodge warranties the Cummins engine for 100,000 miles. If you buy that engine from Cummins & have it installed in a delivery-type truck (Snap-on Trucks, etc.), you get a 300,000 mile warranty. I don't believe Cummins would provide that warranty thinking that there is only a 50,000 mile "buffer" between the end of warranty & when the engine needs to be rebuilt.
Many of these million+ mile engines achieved that mark without "creative" oil & filtation products.
I know of one 94/95 Dodge, that hauled/delivered trailers all its life, with 1,153,000 miles that used Shell Rotella 15-40 with Fleetguard filters. OCI's at 5000 miles.
My understanding is that the oils of those days were not of the quality of todays oils. The Fleetguard filters, in those days were of cellulose construction. Nowhere near as good as todays Stratopore filtering media, which, makes this even more amazing.
The highest mileage Dodge/Cummins that I heard of, without an engine rebuild, was 1,250,000 miles.
I'm beginning to think the benefit of the use of fully-synthetic motor oils with by-pass filtration, with Cummins engines, is the extended oil drain intervals, which, would be quite a convenience for those that drive extreme numbers of miles.
These engines seem to be able to live long, productive lives with just the use of quality conventional HDEO's, filters & regular OCI's.

It is hard to say "prove it" that an engine will last longer with syn oil vs petro oil.Amsoil advertises million mile with their filters and oil but gulf coast does the same with their filters and Shell Rotella oil. Chevron oil amd Mobil also. The life of an engine is how it is driven ,how it is maintained,and the most important luck .5,000 mile oil changes with a syn oil is a waste of money.
