Relevant page in the pre-recall owner’s manual. So basically avoid B5-B20 but adjust service intervals if you have to run it, and no more than B20.
I’m very curious to see the new addendum post-recall. I know they now require a fuel filter change every oil change, instead of recommending it every other oil change.
It’s also complicated by “renewable” diesel, usually seen as R99 around here. Apparently this is more similar to petrodiesel in terms of lubricity, flow, cleanliness etc so requires no adjustment. But the pumps have to have a legal disclaimer saying something like “more than 20% biomass-derived etc” which can confuse matters between Bxx and Rxx fuels
For me, if I couldn’t have gotten the Gladiator with a diesel, I don’t think I would have bought a Jeep at all. People with similar builds to me (ACCC, 37s, armor, lift, etc) get 12-14 mpg real-world on gas and I just couldn’t live with that. I’m getting 23 best-case, and ~19 avg. I did install an aux tank to help buffer supply issues. In practice I use it more to double up when fuel is cheaper (I drive by a lot of Indian land on the way to my destinations)
(the torque is spectacular too! Absolutely no need to regear for 37s, at least when not towing, it’s still very fast when I put my foot down, and still sees 8th gear on the flats)
