Bet if you really ran the numbers, in the course of a day you might save half hour, unless you are speeding in the diesel. Of course that does not account for the assault on manhood of somebody passing you.

Understood. Part of it is the “comfort” of the drive. Like buying a Caddy instead of a Kia.
But also take comfort in how durable those 6.2 Ford motors are. And being a 350 even though it’s a 2015 it got the heavier trans (the same one used behind the diesel, but the std 6.2 F250s switched to a lighter duty version of that trans in 2015 iirc, going forward until the 10speeds came out).
I’ve personally used a 2012 and 2015 for work, towing stuff that most (except for the jelly folks) would say “need a diesel.” And being company rigs, drove em like a rental.
Those engines are largely flawless, even working hard and higher than average duty cycles.
You don’t have to worry bout nothin coming thru the hood unless you accidentally punch a hole in the oil pan first!

That screaming of the engine is what gas engines need to do to make their power. All of them do it. Nothing is coming through the hood, diesels make their power at a much lower RPM. Some people can't stand that high RPM. Your options are deal with the high RPM or get a diesel.

A screaming (hi Revving) engine. Does not produce a relaxing drive.
Don't get me wrong I understand that how the gas engine makes its power.
I still don't want to listen to it scream for the entire drive.
In time the noise wears me out....LOL

My Ford 6.2 gas does not need to scream, to pull my FW up a 7-10 percent grade. I've never needed more than 4K rpm, even double towing, up a 7% 3.5 mile climb, which includes lots of curves, and speeds of 35-55 mph. At 3-4K rpm, it is very smooth and quiet IMO anyway.
Maybe I'm more used to real screaming rpm, from years of riding crotch rockets? My current Yamaha FZ1 redlines at 11,500 rpm, and while it does have an exciting scream, it is very smooth running. First gear at redline about 90 mph. It has 5 more gears to go! Due to factory exhaust valve tuning, it will handle 40 mph in 6th gear nicely. Top speed 170+
The Ford 7.3 makes good HP and TQ, at lower rpm than the 6.2, and many other gas engines as well.

Honestly, its the exhaust brake and low rpms of the diesel that keep me inclined to buy another diesel when I upgrade this truck in a couple years.
Being able to safely control speed going downhill without worrying about heating up my brakes is very comforting. Until a gas engine can get similar compression braking, it'll be hard to change my mind.
The other thing I love is the general lack of shifting in the diesel. Set the cruise at 68 mph and drive. Rolling hills and the turbo spools up a little and it keeps chugging. If I see a large hill coming, I downshift to 5th and let the turbo spool. When I had a gas engine, those little hills would downshift and rev the engine and the bigger hills would downshift even more and have loud revving up the hill. I know its fine for the engine, but the noise is annoying and tires me out more quickly.

Well if it a single lane road there will upset with you!
If a multi lane road, you run the chance of a nasty rear end collision.

Unless you are strictly driving in mountains, not a big deal. Most of the time our old V10 cruises a little over 2000 rpm. Can't hear it over wind and tire noise.
While you need to build some rpm, you don't need to red line it. Rarely take it over 3500rpm and have no problem keeping up with the semis. With the new more powerful engines mated to the 10 speed, it should be even better.
Of course this presumes you aren't trying to pull 16k or something silly. North of 14k 15k the extra power of the diesel starts making sense but that isn't what the OP described.

If I had some way to prove it I would bet most people driving diesel spend more time above 90% of redline than gas engine drivers do.

How much more sound absorbing is put around the diesel?

I have a kinda different look at this idea.
Has anybody seen a side by each comparison; Same gears, engine size load, exhaust brake on diesel and spark fired with closed throttle holding back on a down-grade?
Then think about this part. Something not involved in normal engine control must happen for the exhaust brake to began to slow vehicle. A bad electrical connection, no engine ******. OTOH, the gas engine, closed throttle is the default, engine braking will work even if engine will not run.

Unless your going downhill I doubt your V-10 stays at 2000 RPMS simply because diesels are generally in the 1500 2000 RPM range not gassers.
I do agree the gap is closing somewhat with the coming of 10 speed trannies and the 7.3 Ford gasser.
Nevertheless diesels have massive amounts of low end torque that improve your towing performance and experience even if your towing an 8K trailer.
We tend to focus on performance factors like RPMS and torque, but on a more basic level it's about the experience.
A diesel provides a much more relaxing, comfortable drive. In the end that is what you are paying for when you choose to go diesel

^Just an FYI for many who state RPMS. The S on the end is incorrect, as the M is for minute, not minutes. Now back to regular programming. ![[emoticon]](https://forums.goodsamclub.com/sharedcontent/cfb/images/smile.gif "smile")
