Ford 5.4 engine vs. 6.0 diesel

Hey everyone,

I am looking for a ford f-250 or f-350. I was wondering in the 250s what the gas mileage is on a gas 5.4 vs a diesel 6.0. How much more power does the diesel 6.0 have vs the 5.4. How do you all like these engines, any problems? I would like a diesel 7.3 or maybe a gas 6.8 but I'm having a hard time finding these in a truck I like, so I'm trying to find out if I had to go with one of the others which one would be best.

Thanks

While I don't know what mpg figures would be, I would get the diesel if at all possible. They have more torque at lower rpm=better towing. They will normally get better mpg with a trailer than some gassers do without. They tow more, do it longer, with less stress.

Diesels will go 300k miles or more if properly maintained, while gassers will go 150k or more. Maintenance is normally higher with a diesel, but if you ask anyone what will pull 10k lbs of trailer, mowers, sod, mulch, or whatever up a hill without a hiccup or the motor sounding like a yugo on meth, then diesel is the way.

A lot of the companies around here started buying the V10 fords because the fuel milage is about the same as the diesel pulling and gas is 50 cents a gallon cheaper than diesel fuel. I run a diesel but when it comes time to replace I will probably go with gas buy the truck cheaper fuel cheaper trade off sooner and keep a newer truck around.

Alright. I'm thinking if the 6.0 doesn't get any better mpg then the gas 5.4 and they are close in power, the gas and maintenance is cheaper for the gas engine. I have also heard that some people have had problems with the 6.0 diesel. I have heard right when the 6.0 came out it had some problems but the longer it was out they started fixing the problems although it still had a few problems.

the 5.4 and 6.0 are no where close to comparable power wise.

And the 6.0 has had its problems.. But get an oasis report from the ford dealership(its like a Carfax for a diesel, strictly from ford) and if its been a problem free motor then buy it.

Why does everyone think maintenance is higher for a diesel engine? What does it need...Fuel and air, no plugs & wires, no disributor. Look at all the stuff on a gasoline engine. In the long run, Diesel is more economical than Gas. That's my opinion. And I run 2 Diesel trucks, One is a Dodge Mason dump, The other is a ford F-350 Utility body. They are both monsters, And that F-350 w/turbo prit-near flies, stomp on it, and it is lift off time.

I have 2 2002 7.3 powerstrokes and a early 90's 7.3 non-turbo. He is right on the maintanence. It costs less in the long run. i can get 300k plus on a diesel and still drive work out of it. I would stay away from the 6.0's they are real bad about blowing head gaskets and if you put a box or injectors in them youll have more problems than that. There a good motor they just dont hold up. I would look for a 99-03 with a 7.3 youll have that truck 10 years later.

I remember back about 18 months ago when diesel was $5 a gallon a whole lot of people crying here on Lawnsite about it. There is no way in the world I would get sucked into a diesel unless I absolutely, positively must have it.

Diesel is already $3 a gallon in spots here in NC and as high as $4 a gallon in California and $3.80 in New York.

They are raising the fuel prices so slowly that hardly anyone is noticing. But I am and I'm not happy about it.
