I am in my mid-fifties and the only time that I have had to have a vehicle towed was when a transmission went out. I had to do some field repairs when the crankshaft pulley bolts came loose on my 460, my diesel tractor could barely drag itself back on the trailer when the EGR valve stuck and the hoseclamps came loose on my Cummins. Since I have spent a lot more time with gas engines I would have to give the nod to them.

Since I have spent a lot more time with diesel engines I would have to give the nod to them. Hey look, our opinions cancel each other out.:B

I`m also a diesel tech as well as gas engine tech. so yes from both perspectives the diesel isn't what it used to be. sure if you want 900lb feet of torque out of a 3/4 ton truck great, but it has to be able to make it back home! and as far as fuel mileage, diesel again isn't much better than gassers.

Ask any smart diesel tech what they drive? chances are its a gasser. If not, its an older and more reliable diesel.

Now this is funny coming from a "diesel tech" portraying them as heaps that can't make it home and don't get better mileage! Lol.

Now, my new 5.3 Silverado claims 18-20 mpg hauling @ss on small bald tires across eastern WA, and I believe it. AND that's dang impressive. Same truck, I can hook a 6klb trailer, same route, slightly slower and get 9 mpg.
Any run of the mill "pos" diesel would embarrass it at the gas pump.
Yes gassers can pull down some seriously impressive mileage numbers I'd not have believed even a few years ago. But it's under ideal conditions.

From the get go...diesel has an advantage.

Both in BTU's per measure (gallon) and higher compression ratio (it all boils down to PSI on the piston top)

But, out of context most discussions like this...

Gotta take into account some of the many variables on the table...that is often left out of the discussion...

First, there is no way to make up for the higher BTU's per measure between diesel and gasoline. Period...


Often left off the discussion is that at any given speed (whether running empty with no cargo/other people/trailer/etc) it takes way less than the ICE's maximum ratings (both HP and Torque).

So a gasser can get lots and lots more MPG than older designs, with the higher BTU factored in or in consideration/allowance

Another is to pavement gearing ratio's vs HP/Torque/RPM curves for that ICE.

Throttle setting vs RPM will be way lower in both, as torque is both higher and had at a much lower RPM

Of course, there are other attributes to consider and too much for any single thread to cover

Blue collar translation.
Get a diesel if you want to tow some big sht up mountain passes without your 4 ways on, unless your allergic to diesel fuel or want the best gas engines produced to date!

So will they keep the 6.2 for the F-250 and F-350 and only use the engine in medium duty truck's?

I'm pretty sure the 6.2 will still be available since it was still listed on Ford oil type matrix that leaked out.

As for fuel economy on the last pickuptrucks.com gas test I believe it had the best fuel economy compared to the 6.0 chevy and 6.4 hemi.

And.... I have a fleet of over 500 gas and diesel powered vehicles with statistics and analytical data on how much we spend on them, how much down time, and our ROI. Not to mention four Ford medium duty dealerships. Not to mention oilfield customers with light and medium duty trucks like Schlumberger, Haliberton, and various others that we service. So sorry, but not sorry because you saying that gas engines don't break down(especially when used in the same duty cycle as a diesel) is a load of crock.

And no, even our best diesel techs still drive diesels along with gasers. Heck, even some race them at our local track.

Just a rounding error, I have it on good authority it's the 7.4 come back from the dead LOL.

So will they keep the 6.2 for the F-250 and F-350 and only use the engine in medium duty truck's?

This engine has been in the "real soon now" stage for almost 5 years ! The big debate always was how big was it going to be. The clear bet was larger than 7.0L.

The second "discussion" that has been going on, is similarities to the current 6.2l (2 valve, 3 valve, OHC, pushrod ?)

Third issue is fuel economy and hp/torque. The 6.2L never had "great" fuel economy, but most people would say it was better than the 6.8L V10.

They may have different versions but the one that I have been hearing the most about seems to be 2 valve with pushrods. It will fit in class C motorhomes on the E450 chassis. Simple, relatively low RPM, compact and efficient. And yes the 6.2 is not known for fuel efficiency.
