Diesel truck with best MPG

[megaboz]

How much pulling power do you want? For years 318 Detroit Diesels hauled 40ton of freight plus the trip from coast to coast over two mountain ranges. How much power does drag racing Bubba need with a trailer full of cattle or horses? Are you one of those passing at 75mph trailer towing idiots ?
The 425-450HP direct injected gasses will trailer just fine.
The current port injected 345 and 403HP engines are plenty now.
Who wants a diesel when the gasser burns a little more of the cheaper fuel. Cheaper to purchase, cheaper to maintain and lasts just as long.

I don't haul like a freight train, but I like the steady pull and not the neck snapping gear dropping of a gasser that has to nearly red line to stay 20 MPH under posted speed limit when hauling heavy.

And while I don't need to speed, I prefer to be able to be close to speed limit so the idiots on the road don't run me over or run me off the road because they don't know how to pass.

Taking purchase price out of the picture for purchase of truck, my diesel is cheaper to run in the MPG market. Towing even more. Some maintenance items are more costly but in the end it will out last a gas truck, so when you have to buy two trucks to my one diesel, which one was really more expensive?

Its all relative, buy what you like, believe what you want. Just enjoy the ride while the Dino fuel is still here. LOL

Diesel truck will not last any longer than the gas truck. The frame and body rust out/wear out at the same rate. Engine life of the diesel does not exceed gasser life anymore. Back in the 1980's, yes there was a difference.
You can thank the EPA and CAFE for ruining the diesel.
The current port injection gassers are compettive against the diesel. Just wait until the direct injection gassers are released. Cheaper per mile to drive either empty or loaded. Cheaper to purchase and service during the entire life of the vehicle.
HP is HP. 345 HP of gas or diesel power does the same work per hour.

Yes, but the diesel will do it easier/faster than the gas engine because it will nearly have double the torque.

Do the math. 800lb ft at 1500rpm is the same amount of power as 400lb ft at 3000rpm.

There is no doubt the newer gas engines can tow similar weights to their diesel counterparts. In most scenarios the gassers are cheaper to operate and maintain.

Here is my take having owned 2500 gassers and 2500 diesels:

If you can afford a diesel, just get it. If $$$ isn't an issue, I have never heard anyone say they wish they would have gotten a gasser--- excluding mechanical problems.

I had a 2007 Chevy 2500 gasser and I upgraded to a 2009 Dodge 6.7 Cummins. There is NO comparison to the power difference. Does it cost more? Yes. Does fuel cost more? Yes. Was it wise financially? Not really. Could I afford it? Yes.
Was it cooler and more fun? Without a doubt!

Sometimes you just gotta buy what you want and makes you happy.

How many of you guys spent $25,000 on a new tractor when a used one for $13,000 would have more than sufficed?

Now excuse me while I go fill up for $130 and go do a 3 gallon oil change. (Not kidding) Haha!

800 = 400?

My point is that the diesels have more torque at lower rpm, thus less wear and tear doing the same amount of work.

I would think about getting spray on bed liner in the wheel wells and around the bottom of the door.

is smilar to what I would be thinking about.

Yes 800 lb ft at 1500rpm is equal to 400 lb ft at 3000rpm. Did you not pass your high school physics class?
Just how are your saving any significant wear with the reduced Rpms?
Gassers easily go 300,000+ miles now and with less service than the diesels btw.
Rpm and wear is only a factor with marine propulsion units, power plants and irrigation systems.
There is no measurable difference in wear in the gasser vs diesel due to rpms.
If you were really serious about reducing wear. You would be be plugging in the block heater and using a multi weight synthetic oil. To limit bore/piston/ring wear before coolant reaches 180F. And to limit bearing wear before oil pressure provides enough oil to make a hydro dynamic . A
A completely worn out 300,000+ mile pickup rarely runs above 10,000 hrs.

Doesn't help. The stuff bubbles and holds salt and moisture against the metal. Oiling twice a year and pressure washing salt and mud out of crevices will get a chassis to 15-20 years instead of 10-15 years. This still leaves items like rotten brake and fuel lines. Rusted through rear diff coves, fuel tanks or oil pans. Any work starts to require a torch or penetrating oil to reduce the number of twisted off fasteners.

OK for sake of argument I will you the 400 =800 argument (especially since I saw the same argument stolen from another site). But while you are running twice the rpm to do the same work, I am putting less wear on my engine because it isn't turning nearly as many times.

Regardless, I like my diesel. I didn't say you had to.
