Official Gramps' Memorial Eternal OT Thread

15 isn't bad. I got 15 with my 5.0. I get about 18 with my deisel.
Yeah there isn’t a lot of lift in my opinion on trucks with gas mileage. The diesel mileage increase comes from the higher energy content in diesel vs gasoline. That’s just physics. Trying to push a very large brick down the road with lousy aerodynamics is also just physics 🤷‍♂️
 
I'm not disappointed with it at all, it's comprable to the 6.7s we have in the fleet. I pulled our big JD skid steer with it with no problems, didn't miss the diesel
As I’ve tried to tell people over the years towing big loads is more about handling in emergency maneuvers and hard braking. You need a good sized tow vehicle to stop the tail from wagging the dog. A 5.0 has plenty of power to move big loads it just turns more rpm to do it.

Some of the ecoboost get better fuel mileage. My nephew has one and he gets 20 or better. He just got the hybrid version and I haven't talked to him since.

A friend was looking at buy a midsized 5th wheel and asked if I thought his F-150 could pull it. I said sure, it will pull about anywhere you want to go but it might not stop it or control it in big winds.

He does when he isn’t towing I’m sure. Towing is the great equalizer. A local dealership had a rig to sell people on the ecoboost. A 6000 lb load on an XLT with eco boost. Just going down the road at 70 mph it kept going into boost because it needed the power. Aerodynamic losses aren’t linear they are at least squared. Cubed on power I think the drag is squared. I got a lecture on this the other day from one of our fluid mechanics specialists related to an aerodynamic loss estimate we were working on.

I was getting 26-27 with the baby Duramax in my 1500
How did it do if you put a big ass trailer that weighed about 8k lbs behind it? Mine isn’t direct injection and that alone gives more fuel efficiency on gas engines. The low sulphur diesel fuel has about 15% higher energy content.

I'd get one again. I really liked it. Lots of torque quickly. It's a far more reliable engine than the other options.

I have the 6.2 in my AT4 (that I'm selling tomorrow)
That makes a lot of sense. I’d expect a diesel to be much more reliable. The only engine I’d ever want a turbo on in a truck would be a diesel

The camper weighed about 6,500 with everything. Pulled it with zero issues
