Gas VS Diesel F250

[beachbum5]

I am looking at new F250, I have f wheel about 8000lbs. I would like to know gas mileage while towing and not towing, also on diesel. How would gas handle the load?

Thanks

The right question is in which will you be happier. A Toyota Matrix gets me from A to B, but I'd rather drive a BMW.

Different logic here. I could be driving a diesel in my F250, but chose a 6.2 for my liking. it fits my needs, is what I wanted, and I haven't looked back in 3 years. I think with today's engines it is a lot of whatever blows your skirt up, or as they say turns your crank. you can't convince me that I need a diesel and I cannot convince a diesel owner that he needs a gasser. It will never change.

Agreed. I've done the diesel dance and now that I switched to the new gas engine I don't miss the drama and expense that the diesel comes with & i have plenty of power for what I need along with simple low cost reliability and maintenance, plus matching up the truck with lightweight fiver i've saved over $22,000.00 .Now if you have the time and money & a burnin' desire or need for diesel or maybe just for a status symbol then fill yer boots (or rather the dealers boots) Perhaps when I retire in 10 yrs I will look at diesels again maybe sooner who knows but I am a happy camper right now. So get out there and enjoy whatever ya brung and makes you happy cause life's too short.

Mostly agree. I was speaking on average. But some are happier with gas. In my case, I plan to be driving some at altitude in the CO rockies, where the argument for diesel is especially strong. I'd rather have more than I need rather than risk having too little.

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.

I believe you have your numbers backwards.

Most diesel develop max torque at low RPM,this then stays flat and RPMs get the HP at higher RMPs.

Gas gets max torque and HP at higher rpms RPMs to get max torque.

rhagfo is correct. Diesel almost doubles rpm, max TQ to max HP.

Ford 6.7....torque 800@ 1600 rpm...HP 400@ 2800rpm

Ford 6.2....torque 405@ 4500 rpm...HP 385@ 5500rpm

Diesel vs gas.

My son in law put it best. He always ran Chevy's with gas engines and talked about how good they pulled. Then one day he pulled a 20,000 lb load with my Ram Diesel and he could not believe the difference.

"I though gas trucks had a lot of power till I drove a diesel. Now I dont pay any attention to horsepower, for pulling heavy loads, torque matters most".

[MartyMoose]

The 6.7 is a pulling beast. I love my diesel except for the cold days in the winter.... it takes a long time to heat up the interior. I usually warms up about the time a pull into my office ( so I drive our old convertible on really cold days....)
If you live in a 4 season climate, get the instant heat option.

I much prefer towing with a turbo charged engine. The 8000 (loaded or dry?) pound fiver you mentioned can be towed by an F150 Ecoboost with Max Tow and HD Payload.
I've been doing it for 3 years with a 9500 lb fiver. Now that I am ready for a new truck, it will be an F350 Powerstroke Diesel as the 6.2 gasser would be at high RPMs going uphill vs much lower RPMs for the Ecoboost or a diesel. I am going Super Duty because I am adding batteries and solar to the fiver which adds more weight than I am comfortable with for the F150. And any fiver I get in the future will be heavier than the one I have now with stronger construction and more insulation and features.

Please share your experience with the sidewinder and which hitch you are using...as well as the length of your box...in inches, Thank you

One thing about a F250 with the 6.7 diesel it will handle any condition you can throw at it pulling that trailer. Depending on how fast I drive I get anywhere from 12 to 13 going down the road pulling loaded at 65 70 all day long. The 6.7 has more power than two 7.3's.... it is a monster.

i agree wished i had one

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.

[musicman54]

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