What year models do you have experience with? Higher rate of failure with the earlier models?

Worse than this? This is from a 6.7 by the way - a Cummins 6.7.

Everyone's results will vary but that's terrible fuel mileage. I'm still stuck on Dodge - Ram trucks, but if they ever stick me I'm going back to Ford. 300k miles between two Ram trucks and neither one has ever been to a mechanic, a couple of water pumps and a front hub assembly. Plenty of factory recalls on both trucks but I'm not letting some fool screw up a good truck.

That's OK at least I can change my own flat tire and not worry about getting my hands dirty or breaking a nail.

Plus Ford is out of hand with their warranty stuff. If you aren't running a "Ford" air filter or fuel filter or any other part no warranty for you.


ANY of the 3 new diesels can eat $10k plus on a fuel system repair. The cost of out of warranty repairs is one reason there is a 6.2 Ford sitting in my driveway.

I have a 2017 F250 with the 6.7 and average 19.2 empty 17.6 with trailer loaded.

Out of the co trucks it's like 60% have been in for "fuel" system. That's too many.

The guys like my boss who drive a lot with the new Fords don't get better that 13mpg. I've had a new Ford for a rental and I didn't get better either.

I just threw that out there to mess with you. That picture was taken after an approximate 5 mile pull up a pretty steep grade, with mileage reset at the bottom. 28.5k gross.

The Dodge held around 35 MPH and was limited by EGT's. My 7.3 Fords hold about 15 MPH on the same grade with comparable GW.

I pulled Jelico mountain with a JD track loader - backhoe combination heading south, the Cummins definitely had it's tongue hanging out.

It's a 13 or a 14. Cab and chassis so it's supposed to be derated for longer engine life. Meanwhile the ram 5500 with Cummins has 200k and I just put a starter on it.

Are the 7.3s the indirect injection (idi) or the newer ones with the turbo and direct injection. Also with the EGTs up there you must have it running pretty hot (mods). May not be comparing oranges to oranges although those Cummins will pull.

The old 7.3 are idi the power strokes are ecm controlled.
My Cummins is tuned for fuel economy, but my best mpg happens to be at 125 hp tune and 21 degree timing. You definitely need to watch the egt in the mountains or you'll have a melt down towing.
