2014 GM Sierra/Silverado

The zero to two per gallon difference is with the direct injection gassers vs diesel. Currently the mileage difference is 2-5 depending on the circumstance.
Down the road as all those CAFE and EPA mandated diesel emission controls/complexity start to cost in service. Diesel repair costs past the 100,000 miles and in particular past 200,000 miles will be substantial. The gasser just needs spark plugs, air and oil filters.
A few minutes a day at 4500rpm instead of 2100rpm will make no detectable difference in wear.
The market for European diesel vehicles exist because of the difference in gasoline vs diesel price at the pump. Government meddling with taxes and such. North America does see some spill over however if the VW four banger diesels were excluded. Passenger cars in North America would be far and few between.
Another gasser advantage is that gasoline can be found in any little hick town. Many stations don"t even sell highway diesel.
I can see diesel interest in those who burn the cheaper off road fuel. or if they want an easy 200 extra HP with a tuner so they can put on a smoke show.

Don't forget the rampant fuel quality issues. Of late, the new high pressure diesel systems are taking a beating. Gas trucks are more resilient due to the nature. My guess is that when the high pressure, direct injection systems become more prevalent in the gassers, we'll see more problems with them.

Direct injection gassers operate their injections systems at 10% of common rail diesel injection pressure.

If gassers were so frickin wonderful, they'd be putting them in heavy short haul trucks again too, but they don't.
I've been driving trucks since diamondpilot was born. Logged millions of OTR miles and go all the way back to when gas engines (Ford 534's, etc.) were common in bigger trucks.
I can tell you here and now based on real world experience, gas engines will not outwork, outlast, or get better fuel economy in 99% of most work applications, than a comparable diesel engine in a medium or larger truck. I drove medium and heavy trucks with gas engines in them (not medium like an F-450, but medium like a F-900 tandem, etc.). They were horrible performers and got as low as 4 mpg. Drove essentially same truck 10 years later and it got 9 MPG. Even heavy truck gas engines were routinely shot or consuming large quantities of oil after 75,000 miles. Look at the last of the GM medium duty trucks that had gassers in them. they bring very low resale value compared to a diesel counterpart.
Like I said, if gas engines were all some of you say they are, they'd be common in bigger trucks, but they're not. Thank goodness for that, too. lol

Now in little pick-ups, your arguement makes more sense. 90% of all diesel trucks are purchased to make up for something else missing in the purchasers life. Soon as I see a truck with stacks, lift kit and all that BS, I'm pretty sure there's an insecure "little man" driving it. When I see a stock diesel pickup, more often it's justified (towing, high miles). I think the newer V-8 light diesels are made to have more HP, rev higher and feel more like a gas engine. The compromise for the higher revs is lower B life. The Ford 6L is a higher revving diesel like that.

I think I would avoid any new diesel unless very high miles are being driven or the truck is used to pull extremely heavy loads. There's too many new pollution regs and equipment on these trucks that destroy the diesel's reliability and longevity.

I am driving my first and likely last Chevy Silverado. I have a 2007 that I bought new with the Active Fuel Management engine. It consumes a quart of oil between each oil change, has a random rough idle issue and has very loud lifter tapping noise from the engine. Dealer followed GM Service Bulletin and replaced valve cover that was supposed to reduce oil consumption and indicated a quart every 2500 is acceptable. The dealer mechanic never seems to hear the tapping and the rough idle doesn't kick any codes... This is besides door lock issues, radio wiring issues, etc. I am extremely disappointed. I grew up on Fords, but the Chevy had the recently updated design and I fell for it.... Next truck will likely be a Ford, but I may need to look at the Toyota too. My Great-Grandfather who owned a Ford Dealership for almost 50 years will spin in his grave if I do end up in a Toyota.

I have reached that age in life where you name the vehicle manufacture and I can tell you horror stories about the lemon I owned. Ford has improved quality now, but I have owned a couple that I always kept plenty of change in my pocket and a bus schedule in the vehicle because you never knew where it was going to make a pedestrain out of you.

As to the gas vs diesel. I heard an old truck driver and a young man one time having a conversation on gas engines not lasting as long as diesels. The truck drivers opinion was simple, he said "HEAT" and "OIL". He advised install a larger oil pan on a gas engine, pour in fifteen quarts of oil and change it every 3-4 thousand miles and it will also last a long time.

No he will not, he will see you are buying quality. Now when GM took the bailout I am sure he did a few spins.

Glad you are back in town making stories your own Hay Man???? Duane!

I have no idea what you are talking about. Are you calling me a liar? Are you saying I'm not farming hay in Delaware?
Here's hay we just shipped on trailer behind one of our Fords.

I have a 1995 Chevy that my grandpa bought new. I got it when I was sixteen and I'm still driving it! It is my work truck now I work at a coal mine n it has not had a easy life hauln pulling pushing it way through life and I'm about ten thousand miles away from 500,000 miles original motor trans and front and rear diff! Its Ben one **** of a truck it is about to rust in two tho lol
