Question regarding diesel vs gas

[nicky8668]

Burning aged diesel fuel and def in a modern turbocharged diesel engine is a much bigger and more expensive problem than running aged gasoline in a modern NA gasoline engine.

I have owned both types of pickups and have towed a 5TH wheel trailer. What I have found is I had more power and better mileage with the diesel engine. During cold weather I us an anti gel in the tank which protects the diesel to -30 degrees. Plus I drive it about 20 miles a month.

I had to spend maybe a minute pondering what the F BTDT is/means. I think I did so can I sit with you and the cool kids in the cafeteria?

If I had to pick a gas truck the GM 2500 HD 6.6 gas would be hard to beat. GM really muscled up their HD trucks. In my test drive of a 2020 GM with the independent front suspension I thought the best driving. Way better than Ram and slightly better than Ford.

I tested drove all big three 2020 3/4 ton gasser. I found the Ram is the most comfortable going over bumps. Chevy is also good. Ford is probably the most harsh.

If you go diesel, go 350/3500. Essentially same price, much more payload.

I just traded my 2016 F250 ultra lariat with a power stroke, 6 speed trans. It was a great truck, but I only drove it 34000 in 4 years. It stoped running on a resent trip. I’m a mechanic, but cannot fix it on the road. I had it towed to Ford. good thing we were only 1 mile from the camp site with full hook ups. I figure it was emissions. Well it was water in the fuel. It destroyed the fuel system. It is a non warranty and cost me 10K to completely replace the whole system. Getting parts was a bitch. There on national back order. Only 12 dealers had the kit I needed in the US. None would sell it to my dealer. I told the part guy to pay over book. He finally convinced a dealer in Minnesota to sell it to him. 4 days ground shipping. $1500 core costs. Even though you cannot get rebuilt parts. To do the job they have to remove the cab of the truck, because the engine set so far back in the cab. 4 days labor. New parts came with 2 years addition warranty.
It towed great i loved it, i had a Titan 50 gallon tank and a transfer flow 50 in the bed. 1000 mile range.
But at the end of the day it cost a lot for fuel, DEF, and oil changes. 11MPG towing and 18 empty. Not every station sells diesel. It a 10K option too.

So the new truck is a Ford 7.3 Godzilla with a 10 speed gas engine. It ran 1500 RPM at 80 MPH and got 15MPG. 3.55 rear end. I expect that to go up once it get broke in.
I will burn more gas. But i don’t think it will cost as much as the diesel.

You make me wonder why my highest mpg is only 13. I’m don’t have a heavy foot at all. I also have 3.55 rear end.

Water in fuel you shout have gotten a warning on the dash from your water separator filter. Water is Fords cop out on failed fuel pumps.
Don’t know what you will be towing with that 7.3, but the 10 speed may not overcome that tall of gear.

Thats everybodies cop out. Youve got to drain the seperator at every oil change. The only reason i got a few injectors covered under dodge was because they had done the servicing and hadnt been draining the seperator.

Agree with every oil change at least drain the water separator. But you need to tell them to do it and make sure it is on service order. And ask how much water was in the separator to try to keep the service department on their toes.

The old diesel engines - my nephew put gasoline in my brothers 1999 turbo diesel VW Golf. The car made it one mile. You know my brother eventually after two days of cranking and battery charging he got that Golf running again with no damage to anything!!!

Modern diesel engine are toast if you put gasoline in it. That 35,000 psi fuel delivery system is finicky.

Oh, you can get water in gasoline too and that also is not good.

A diesel has very few problems sitting still for months. The fuel can get stale and develop mold in the system. Use a fuel conditioner once in awhile. Stanadyne or Lucas both work well. The batteries can get drawn down by ECM or VCM after a month or 2. I use knife disconnects and batteries stay charged.

At every oil change?? Ram has a 15K oil change interval, Ford and Dmax are some where between 7.7 and 10K. I drained the one on the 2001 about once a month for the first six months, never found water in the fuel.
When I change filters I order replacements, so I always have a set of filters with me.

Wow, 15k is nuts in my opinion. I do 5k on my company and personal trucks with full synthetic, which is about once a month for me on the work truck and the personal gets an annual change after the summer trip.
