Which is why maybe looking at pre DPF vehicles from say 2007 back might be worth it...? All depending on emissions stds in your state / province of course.

Myself, cannot see spending upwards of 99k CAD on a new truck and being forced to put up with the, IMO, stupidity of lower mpgs due to enforced emissions stds. Seems to me that the more emissions cntrl stuff that is added, the lower the mpgs and subsequently ya burn more fuel...Ie: stupidity.

Tuning is where the emphasis aught To be....on both Gas and Diesel vehicles.

MPGs on diesels actually went up by 20% when DEF came in to the picture. Emissions are basically sorted now. My DPF equipped trucks do a ton of putting around town and I've had no issues.

Haven't read entire thread, I'm sure both have pro's and cons. I just love the way my diesel sounds.


Just for fun have someone drive it away from you with you standing outside. The fords of your era sound a bit different on the exhaust side of things. Kinds sounds like someone is blowing air thru their loose lips. Especially if it has an aftermarket exhaust.

Mpgs went up with DPF eh...? From what? 10mpg to 12....?

I'm emissions Free - No EGR - straight piped turbo bk - PPE Exh manifolds - AM up/ down pipes...

22 mpg @ 75mph...and tuned such that it doesn't blow black at any EFI Live setting.

I get that with full DPF and DEF still on the factory tune. I can wipe the inside of my tailpipe with a white glove and it's still white. What's your point?

No, they're not. One of the trucks at work is OOS right now due to constant re-gen problems and the occasional STOP ENGINE light. The repair bill (bad EGR cooler, clogged DPF, and two gallons of fuel in the oil, source as yet unknown) will probably top ten thousand dollars. This is a Freightliner MDT with only 112,000 miles. Diesel power has jumped the shark.

The last pre-2007 truck at work got about 9MPG...full-height (13'6") box, 250HP 7.2 Cat, 4.11 final drive. The emission trucks do not top 8MPG and usually get about 7, with lower boxes (12'6" or 13'), equal or less power (250 or 220) from smaller engines (Cummins 6.7s), and TALLER gearing (3.91). One tractor has never topped 5MPG in 150,000+ miles. (The pre-2007 tractors got 6.5-8MPG.)

If money was not an issue than the Diesel is a no brainer but since I dont have unlimited funds its not worth the additional $10,500 option to go with the diesel. Most people post getting 10-12 mpg towing with the diesel. I get 7 mpg towing my 42'-12,500# 5th wheel with my 6.0L gas.

Of course a diesel would pull with ease but my 6.0L can pull my 5th wheel at 75mph through the hills of PA just fine

From a pulling perspective a Diesel will always win but dont rule out a gasser if you dont have an extra $10k+ to spend.

Funny how the DPF diesel crowd always leaves out the regen process when bragging on fuel economy which burns a lot of diesel to clean out the dpf which decreases fuel economy.

I see no reason to ever own a full size gas truck. People say "cost," but that cost is regained when I sell it. People say maintenance, and several poorly designed diesel of the last fifteen years have given people a bad taste. My last three Cummins have had right about a million miles total on them. How much "extra" did I spend on them? I did one head gasket myself for less than $500 in my driveway and about 10 hrs of work. I've done three water pumps. One alternator. A few serpantine belts. A clutch and one tranny. Nothing more than that was necessary.
How is that more maintenance than a gasoline v8? I've spent more money fixing my wife's gasoline daily drivers than I have my work trucks! And two of the three I sold for 70 percent of what I paid for them. They made me literally tens of thousands of dollars hauling my mini excavator and skid steer around. Not to mention they passed hundreds and hundreds of swaying f150s and underpowered gasoline trucks trying to tow up hills.
I took two of the three trucks to the drag strip for test and tune nights. Had a blast in them, worked in them, enjoyed them, and the whole time if I had a gasoline full size truck I would have been disappointed.
If I was in the wrong financial situation and I only had 5-10k to I vest in a tow rig, I'd still be much happier with an older diesel that I could work on than a "nicer" newer gasoline truck.

Bottom line is trucks are for working. And for each gallon of diesel, more work is done than gas.


Some people who short trip will do much better was a gas powered truck. The last thing they want is a forced drive down the road to regen their soot clogged dpf.

In addition gas powered trucks are so much simpler will less complicated emissions equipment than todays EGR/DPF diesels.

For our farm/ranch trucks we go out of our way to purchase diesel trucks that are not equipped with dpf's and for the MIL we purchased a gas F350 since she just puts around and doesn't really work the truck.


That makes no sense..... I've had a 2013 and now a 2016. My trucks do a lot of slow putting around. My 2013 went thru 1 forced drive down the road regen. It took all of 4 miles.


It makes a lot of sense if your 6.7 cummins is in the shop for CEL after CEL because of soot and all the Chrysler dealer can tell you is to run a diesel additive and drive with your exhaust brake on. After nine months of this nonsense a 5.9 cummins solved the problem.

BTW... the regens took a lot more than 4 miles.
