...and they said gasoline engines were dead...

CUMMINS is going to offer a gasoline version of the 6.7 at some point. Makes perfect sense in skoolies since the big three IC, THOMAS, and BLUEBIRD offer the 6.7 diesel as standard equipment anyway so having one engine footprint makes it easier. IC offers a PSI 8.8L V8 gasoline engine while BLUEBIRD has the FORD 7.3L V8. I would imagine that any change over will take awhile since they likely have long contracts with their respective suppliers. Interesting article.

There are several lawn services I know of that have went away from diesel one tons and went back to the big gas engines to get away from DEF. A portapotty guy in my area has went back to gas engines in his 450 and 550 trucks says he had too much trouble with the DEF diesels and the drivers running them.

it isn't just Def. too much electronics to get everything to work, plus nightmare to work on them everything shoehorn into engine compartment, plus diesel costs more, hold lot more oil, just no overall savings long term. gas are hard on fuel but just keep working without significant issue. Just stay away from 1/2 tons.

Some people have finally started doing the math... never mind the potential $$ of problems...

The large option price of the diesel engine, the higher maintenance costs, oil change, fuel and oil filters. The DEF cost can be added to the fuel costs, slipping that "liquid cost per mile" dollar value down.

The "fuel economy" gain is not as wide as we like to think it is.

The money spent will not be recouped, vs choosing a gasoline power plant.

I am very familiar with the current Dodge Ecodiesel vs Pentastar V6...

Same fuel economy in the real world, similar performance,  very big difference in purchase price and ongoing maintenance fees.

But the number of diesels being offered in the personal vehicle market by the Big Three keeps expanding?

Someone is making money...

Deny your inadequacies! Keep yer money in yer shorts and buy gasoline!

Happy coaching!

I have to wonder if CHRYSLER is thinking of dropping their 6.4L gasoline engine in the RAM 3500, 4500, and 5500. Since they offer the CUMMINS diesel already, the same provisions are in place. That would give them an excuse to drop the 6.4L but the v8 stalwarts would understandably be peeved but time will tell.

For me the switch back to gas pickups was after buying a new 2005 6.0 Ford diesel one ton and in less than forty thousand miles ford had put three complete engines in the pickup and the MPG on that truck was bad. It always seemed to blow the engine five to six hundred miles from home also. I had always had a 5.9 in a dodge or a 7.3 in a ford and never any issues and MPG was good. I sold that truck in 2010 when the warranty's were running out. Switched back to the Ford's big gas engines in model 2011 year and never looked back.

The 6.0 is a great engine once you "bullet proof" it: EGR valve and cooler delete, better oil cooler, ARP head studs, etc. Mine has been flawless since I did that a few years ago and 350,000 kms. Lots of power (torque), and good on fuel too.

But yea, if I was looking for a new truck, I would consider a gasser. Although at my stage in life, I will likely prod the old Powersmoke to last me till the end...

the only good diesel was the 7.3 and turbo versions. the newer ones were all problematic.

I would agree with that up to 250,000 km after that if I had a drink with ice in the cup holder it wouldn't start.
Very hard starting in cold weather for a 2001 7.3 I had since new

I have a 93 7.3L IDI, and a 96 7.3L Powerstroke. They both start just fine without being plugged in. The earlier models still outshine the newer ones, and they cost far far less. The current ones have too much power and don't even sound like a diesel. The Ford gas V10 had a few problems, the 460 V8 was a solid engine, but sucked the gas pretty quick.
