my take is any eng is only good for so many revolutions till the wear takes it's life. If I can turn my 7.3 23/2400 rpm with heavy wgt getting 11.5 mpg doing it the life and cost will be better than a 5000 rpm gasser struggling and getting 7/8 mpg.
My invitation still stands. Bring your gasser and we will both pull my trailer and compare speed, time and mpg on some steep grades. Just remember my diesel gets better milage tuned that it does stock.
And try some of the new diesels @ 400hp and 800 lb ft.
64Thunderbolt, you just don't get the gasser way of thinking!
If the engine isn't spinning 5,000 rpm it isn't working, and low fuel mileage is a badge of honor!!
I like Spud57's "Stock to Stock" so what if his is 10 years newer than yours.
I dumped my gasser, and have never looked back, stock my 5.9 diesel with 3.55 gears, pulled my 8,500 5er WAY better than my F250 with a 460 FI gasser and 3.73 gears. It did it with 100 less cu. in. of displacement at half the RPM, and twice the fuel mileage.
If with gas you are getting 6 mpg pulling a load, and I am getting 12 mpg, I would say my engine is working half as hard as yours.
They will both do the job to a point, but diesel will not work as hard, that is one of the reasons they last so long.
