I realize this is an endless debate, but two main reasons cited for using diesel are fuel economy and longevity. If you are putting a ton of miles each year on the truck, then diesel makes sense to me. But if you are not, it seems hard to justify the additional cost, both up front and for maintenace (which is higher for a diesel). A good gas engine can go 200,000 miles, for diesel you might double that. But if you drive 15,000 miles per year, and keep a diesel for 300,000 miles, that means you would drive the truck for 20 years. I am not sure I want to own a truck that long. A lot of other advances get made over the years, and there are a lot of other things that will break that can be expensive to fix besides the engine.

So for most people, it seems like gas makes more sense economically (though I realize in some applications one might need the extra power a diesel can sometimes give).

Am I missing something?


You are missing a diesel. Replacing injectors, etc.

I agree with you.
1. Diesel trucks cost a lot more
2. Diesel fuel costs more
3. Few keep a truck 10+ yrs.
4. Diesel does not pay till you drive 25k miles a yr.
5. Diesel mileage is way overrated by its addicts.
6. Gasoline vehicles are more reliable (read diesel forums)
7. Gasoline vehicles are cheaper to repair.

Can you share with me which gasser is putting out what the stock 650+ torque diesels are providing?

Based on what you are saying I am sure they are out there . . . but I curious which one?


There are no gassers putting out the torque of the diesels. I never said that. I mean no disrespect, but do you not know the difference between HP and torque or just choose to ignore what I wrote? I posted HP numbers the 8.1L and the V10 previously and the 8.1 was a little less than the dmax and the V10 was actually more than Ford's diesel. A transmission is a great equalizer.

Heck, if torque is all that matters why not skip the diesel and go to electric? A Toyota Prius has 258ft/lbs of torque in its puny electric motor (with a whopping 44hp).

Torque is not power, it's force. There's a big difference. Besides, by the time you gear the diesel back up (or the gasser down) the rear wheel torque is the same.

Nope.


Did Oldtymeflyr edit his post, or you?

I did. I added -and torque- in parentheses to indicate it was my change, and to show why the original statement was incomplete, or misleading. Torque makes all the difference in hauling, pulling, and accelerating.
Sorry that I wasn't more clear.

[quote=rkortes][quote=JIMNLIN]your correct about a endless debate so why bring up another thread on why you choose to drive a gasser. Its been covered many times and you don't have to justify your decission to not own a diesel. It is becomming a moot point as a diesel is DMAX/Cummins vs a little smallblock with big hp [apples vs oranges. Now the PSD has a close equal with the V-10. When Ford drops the V-10 then the PSD will have no compitition either. Not all diesels have or are more expensive to maintain [regular scheduled] than a BB gasser equivelent. These type of post pop up from gasser folks every time diesel fuel gets higher than gas. JIM[/quote]Hmmm.... going out on a limb here but I don't think anyone's holding a gun to your head making you read every thread. Skip it if it bothers you.[/quote] thats funny. Did you have something to give the OP on his comments or are you just a forum police or just grumpy or just...... Something you ate maybe.......... When you get to feeling better give us your opinion on the topic. JIM

If you can't afford a real truck with a diesel engine then by allmeans get yourself a cheap undersized truck with a gasoline engine and a manual transmission and a load of aftermarket junk to try to get enough power to take your rig up a hill.

When we see you with you hood up as we travel around the country we'll feel sorry for you. But we're not as quick to stop as we used to be... we stopped to help one family that was broke down and the guy started telling us how superrior his gasoline fueled truck was with all if its add ons, loud mufflers, lifts, oversized wheels, etc.

AND HE WAS BROKEDOWN!

What can you expect when YOU make bad choices... and talk yourself into believing them?

Kind of ironc coming from a guy whose "real" engine produces 40 HP LESS than the stock gas engine in my truck.

If talking trash about others' choices in trucks makes you feel better, go for it.
