Gas VS Diesel F250

Torque curve.

The diesel peaks in both horsepower and torque at almost the same RPM (usually around 3K in motor vehicles). Gassers peak torque at about 1800, but the horsepower doesn't build up until much later in the curve.

The total explanation is, of course, much more complex but that is the basics.

Can some one explain something to me.
Why is it when a gas engine that has a 6000 rpm red line is struggling when it is truning 5000rpm. But a diesel engine that that red lines at 4000 rpm is hardly working at 3500 rpm?

Living in Oregon with an abundance of mtns and hills diesel is the best way to go. I tow 9000lbs with a 12 CTD and would never want to tow that with a gasser. I towed 7300lbs of TT here with a 5.4 gasser and that was enough. The 6.2 and Ram 6.4 are way better than the 5.4 for sure, but any gasser is going to be shifting a lot compared to a diesel. IMO it's how often you tow as to how tolerant you would be. All that shifting is what eats into the mpg.

Just came back from there drove past Mt Shasta again the 6.2 handled it with no problem except for all the semis getting in the way.

liveing in oregon diesel is the only way to go have used both had a 460 ford now have 7.3 no problem

Agree with others. 8000# is not much so it comes down to how much towing do you do & where do you go? East of the the Appalachans the grades are easy so if you are a weekend warrior with the occasional longer trip IMO spending the extra for a diesel is not worth the $$.

Coming from boating world, the views are similar. If you are not running over 100hrs a season the diesel is really not worth having. Diesels really don't come into their own unless there are hours of hard work to be done.

My 6.2 has no problem pulling our fiver up the steeper grades mostly at the speed limit. Comparing a modern 6.2 to a GM 6.0 is apples to oranges and I know I own both. While the 6.0 is a great engine it isnt nearly as capable as the 6.2 . I have also owned a 7.3 and would put the 6.2 as slightly ahead of it capability wise as well. The engine braking is phenomial I hardly have to use the brakes on steep downhills at all they, are stone cold when I get to the bottom. And I have no problem using cruise either.

This old, but still relevant articles would make you think the differences between gas and diesel would make occasional high climbers happy enough with their gas motors. 2010 3/4 ton

You might get a little more info on the 6.2L forum on the FTE site. Here. An F350 6.2 with the 4.30 gears will probably be my next truck, if and when the ol'e 7.3 dies. LOL

You might be waiting awhile.;)
