F250 4x4 6.2 vs 7.3?

[WilliamBos]

Looking for info from those who have owned ir own both engines. How do they compare on mpg?

Would love a regular cab F250 4x4.

Depends on many things.....good discussion here

6.2 vs 7.3 Fuel mileage question - Ford Truck Enthusiasts Forums

2017+ Super Duty - 6.2 vs 7.3 Fuel mileage question - Okay, another fuel mileage question. Long story short, I live in California with high gas prices and I'm looking at ordering a new F250 Lariat but I'm stuck between ordering the 6.2 or 7.3 engines. Realistically, the 6.2 will be fine for what...

I don't know about the 7.3L, but after 10 years of running an F250 6.2L my overall average fuel use is 12mpg. Highway 14.2-14.9 mpg depending on terrain.

My early '99 7.3 in an extra cab short bed 4x4 has always gotten right at 17 mpg average. It's the automatic with 3.73 rear. Pulling a fully loaded 14k gooseneck it got right at 15 mpg.

A gasoline engine pulling a fully loaded gooseneck getting 15 mpg, that's the one I want if that's legit numbers, unless your talking about a diesel 7.3.

He said early '99 so obviously a diesel. I have a '01 7.3 and get about the same mileage.

My brother used to own the 6.2 and it blew up right after it went out of warranty. But that was 8 years ago, so things might be better now. I used to own the 7L in a 250 and it was a horrible gas guzzler. Basically it went from gas station to gas station.

Yep, similar.

This is a good question. I'm curious to hear reports as well. Everything I've read says the 7.3L is a workhorse!!!

You have a 7.3 Powerstroke, awesome engine. But the 7.3 I am referring to is the new pushrod gas V8, named Godzilla.
