For the 3.0 diesel people that want a bigger fuel tank

You should own a 6.2 before the diesel like I did and you'd appreciate not having to fill up until 360+ miles on the tank. I was getting like maybe 240 to a tank with the 6.2 but those numbers take into consideration towing, which is the main reason I bought either of them. The 3.0 with nothing in tow should get upwards of 500 miles to a tank, the 6.2 on a great day would get around 320 miles. At any rate, yeah, what those above said, those tanks should be for gassers, not diesels.

Heck, if I didn't tow anything and had a 43 gallon tank on this diesel, I'd need to fill up like 4 or 5 times a year . . . maybe.

How is your DEF usage when towing?

Can't answer that as of yet, just traded the 6.2 for the diesel 3 weeks ago and haven't towed anything. However I've been told the DEF usage increases substantially when towing. Mileage numbers for the diesel in my last post is based on what friends get with theirs when towing weight similar/greater than what I'll be towing.

Two reasons I traded for the diesel: 1) the 6.2 main bearings went and left me stranded at 2 a.m. back in June and I've heard horror stories of people going through more than two engines (my sons friend is on his 3rd and I know of another guy on his 4th) . . . didn't feel like being one of them, especially since the average tow distance for me is a 390 mile round trip to the Chesapeake from WV with a boat in tow. 2) my research of the diesels found no major engine issues. I loved the getty-up-n-go power of the 6.2, but I need something I'm not worrying about making it on the aforementioned trek.

I had a ‘22 zr2 with the 6.2 and got a ‘24 with the 3.0. In answer to your question, DEF consumption when loaded/towing is my biggest complaint. Really loaded up with gear and pushing a headwind on the interstate at 85’ish or pulling a 16ft bumper with a Ranger UTV across the state to deer camp…it will drink it.

Other than that, it’s been rock solid and gave me the mileage per tank I wanted for hunting trips out west, torquey as hell for off-road use, smooth motor/tranny combo, etc. I’ve got 18k miles or so. It’s not a 6.2 but was never intended to be.

I heard the same elsewhere, which is why I asked. Makes me wonder why, though. My 6.6 Duramax doesn't do that. Empty, I get about 2,500 miles out of a box of it...And that really doesn't change much when it's loaded up, plowing down the interstate.

my son has a '22 high country 6.6 duramax and i asked him about his DEF consumption when towing, he said his drinks it. he said he gets around the same as you out of a tank when not towing. when he tows, though, he's usually towing 5+ ton earth moving equipment.
