6.8L Diesel

Have a 2006 F350 with the v-10. It is a beast / never has a problem going over hills etc.

I would write exactly the above...except I am a Ford person...The V10 revved alot and I got many compliments from the gas station owners.

I had a 1999 V10 F350 and Loved it as it was super reliable and I had no spark plug issues BUT like was said before anything over a 12K 5er forget it at the time I had a 34 ft Montana and it did just fine once I traded up to the bigger 5er's I had to put it out of it's misery it SCREAMED for mercy at 5K RPM going up the mountain passes at 40MPH if i was lucky and got about 6MPG so Traded it for a Duramax Diesel and smooth sailing ever since

Being a mechanic at a ford dealership i saw the engine guy replace quite a few of the V-10 3 valve engines they also have a problem like the 5.4 3V to shoot spark plugs out of the head destroying the COP and needing a helicoil insert.

i would personally prefer a 2 valve V10 ive owned 1 of each of the 2 valves *4.6 5.4 and 6.8* and never had any issues with them.

As he said these are high RPM motors let them spin my F150 did not make max HP and Torque till 4300 + RPM!!!.

Keep up on oil changes these engines need oil changed regularly due to the over head cam design.

Friend had a 6.8L excursion and it would get between 6MPG **towing 10K** to 10 MPG *Unloaded*

The exhaust manifolds seem to be a real issue too and can get really costly quick. Not nearly as many V-10 parts out there as 5.4 parts.

Good luck!!

Diesel? No it is a gasoline engine! The V10 has been around for a long time. Early ones had problems swallowing spray plugs, but they seem to have sorted that out. Be advised they love to rev up. Had one in a class A, in Fla things are pretty flat, not many hills, but driving down the Interstate, it would down shift and rev up to 3.800 RPM just going over an overpass. I had to sell that Class A, could not imagine driving anywhere there were hills or mountians with that set up!

I have one in my F250, 170,000 miles and still running strong. It will pull my 7500 lbs TT down the road in overdrive 70 mph @ 2,000 rpms.

Hi Mickey,

I owned a 2 valve Triton GAS V10. It is a fantastic workhorse and I would own another one if I were looking for a 3/4 or 1 ton Ford.

It behaves similarly to the less powerful 5.4 Ford V8. Basically you will be turning some RPM on hills to make the HP you need to pull the hill. Do not lug these engines, let them spin some RPM. It is not a diesel motor but it will do a great job.

I would probably limit my weight to about 12k lbs max with the V10. Anything more and I would look for a diesel.

Oh, one more thing. Look for a 3 valve V10 which started in 2005 and up. They have a lot more power. I think you can still get a V10 in new F450's.

Thanks!
