I'm looking at a '11 F250 and I like the new 6.7's specs but part of me says its tough to justify the extra 8 grand. Any 3/4 ton or 1 ton diesel owners think the motors are worth the cost?
I heard this 6.2 gas wasn't bad.

Do you often tow a boat or a trailer?

Do you really need a few more rubberbands? If you are questioning it now, then you know it won't be worth it.

No. Especially not a new one. I did a cost analysis when buying my new truck and it took something like 11 years to make up the difference between upfront cost and maintenance costs of a diesel vs gas

Idk man.. you seem like you make a good living, so I'd go all out. Why hold back ya know? You're about to make a big investment in which the value depreciates the second you buy it. Take your time with this one Z.

I guess the only reason I consider it is cuz I drive a lot for the work I do on the side and thats mostly where I'd use the truck. But you can buy a lot of gasoline for 8 grand and I know I'd never keep a vehicle long enough to get the longevity worth out of a diesel.

yeah, typically it only makes sense if you
A. want to keep the truck for 250k+
B. Hual 25'+ trailers daily
C. Haul large loads cross country frequently.

hmm... would it be worth looking into a diesel thats a few years old and like 30-50k miles on it?

Yeah, but they are still like 6-8k more typically

Why not get an F-150 with the new ecoboost engine?

also remember that the 6.7L takes 13 quarts of oil and needs the fuel filter changed every 10k

This is going to sound stupid but I have an F150 right now and obviously my Mustang. And both have fucking corrosion on the aluminum panels due to iron contamination and it kills me to look at it. And the Super Dutys are the only trucks that don't have this problem cuz they don't have aluminum hoods. I don't want to get another F150 and have rust bubbles all over the hood. Although Ford says they took care of that.

I figured it'd take more than that since the 6.0's and 6.4's took 15 and 16 quarts.

My F150 doesn't have rust. What year is yours?

How did u get so lucky?

Mine falls into that range (2005). I guess I'll keep a close eye on it.

pop ur hood and check the underside of the lip. Thats where it starts. Thats where it started on both my mustang and f150. That's why I bought a carbon fiber hood for my mustang. It was killing me.

Depends on where you live and how you're going to use it. I had one for four years - while I liked the vehicle itself, I quickly grew to detest the diesel engine.

If you're going to be running on long trips on the interstate, the diesel is more attractive - diesels running for prolonged periods at steady RPM's are much more durable and fuel-efficient that gas engines. If you're running on short trips (less than ten miles or so) or doing a lot of driving in city/town traffic, the balance quickly tips in the other direction - short trips and stop-and-go traffic eat diesels alive. In particular, you'll put a new exhaust system in about every other year - the vibrations and the sulfuric acid (from combination of condensation and the high levels of sulfur in the exhaust gases) tear the snot out of them. Maybe this has gotten better with the advent of lower-sulfur diesel fuels in the last few years?

If you live in a part of the country where the temperature regularly drops below twenty degrees, think long and hard before going diesel with the smaller car/pickup engines - things start to get difficult below that point. I had to use a block heater on mine when it got cold - and God help me if I had to park for several hours without a plug-in. Moreover - getting quality diesel fuel with the right winter mix is kind of iffy at gas stations - having the right winter mix is critical for smaller block engines. I worked for a trucking company up in Northern New England for several years - we had to use up to a 50% alchohol/diesel mix in the really cold weather to prevent the stuff from waxing up, even in the big Detroit Diesel and Cummings blocks . We had to test and adjust what we had in our storage tanks every day based on the expected weather - while we didn't want our trucks dying on the road, we didn't want to put any more Everclear in the mix than was necessary. Adding alcohol to the mix drastically reduces your fuel mileage and is very hard on non-metallic components such as gaskets.

Do the math....

Diesels get about 3 more miles per gallon, correct? So let's assume 14 mpg vs. 17mpg.

If you drive 20,000 miles in a year, diesel will save you @ 250 gallons...at $3 a gallon that's $750 a year, making your break-even approx. 11 years (ignoring time-value of money!). Now, it also used to be the case that diesel was @ $0.50/gal cheaper, which meant the break-even was more like 4 years. Now, however, diesel runs 20-30 cents/gal more, so you are looking at only $400-$500 in savings per year.

So, yes, doing the math diesel is NOT worth the additional cost.

LOL, looks like our math appears to match!

Get a duramax. Problem solved.

A diesel is not worth it unless you are a farmer or are going to drive eleventy billion miles. I don't understand the purpose of this truck. Especially if you already have an F150. Are you going to trade the F150 in? If so I would just get a F250 with the gas engine that suits you best.

If that is the case I would get the duramax 18 mpg, best tourque, best transmission, best HP, best reliability. Fords new engine could be a great or crap and it will be awhile before that is determined. Based on the history and from personal experience with the 6.4 I would go with the duramax.

You can do anything you need with a gas 3/4 ton.
