Problems with Gladiator V8's (5.7 or 6.8)

[ChrisNLA]

They’re great cars. I don’t care for the autos, they drive completely different from the manuals, but I love that 2016 body style. Especially, in black. Same with C5-C7 corvettes. They drive completely different in manual vs auto.

My previous one was a TR6060 manual car. A lot of fun. The LS3/manual drove so different. the LS3 came on like a light switch in the upper RPM whereas the L99(with VVT unlike the LS3) and the auto just grunts through it. Very linear. More bottom end pull, lighter on the top end HP.

The manual car was a great toy, my auto car I have now is a great going to town rig.

The manual is not "adamant" about 0W20. It clearly says "recommended". Both the 3.6 and 5.7 were built many many years ago when 0W20 wasn't even on the shelf.

I have never seen cam/lifter issues on a 3.6 or 5.7 engine that has run 5W30 from new. And in my personal experience with 6-digit mileage on both engines, I've never had a single issue with either.

I have heard the exhaust manifold leaks on 5.7s around town, but that's easily cured with aftermarket stainless options so I don't consider it a big deal.

Unfortunately, I don't think a FACTORY installed V8 will ever happen in the Gladiator for reasons we've discussed many times before, largely SAE J2807 targets, and so I'm not sure why this section of the forum exists. But, if pigs start flying and the Detroit Lions win a Super Bowl and Jeep decides to drop a V8 in the Gladiator I will be in line ahead of everybody else, so bring a tent.

Hi,
New to this forum, just bought a 2026 Willys Gladiator, and was hoping to puck your brain a minute. Do you reccomend 5w-30 in the 3.6l ? Also would it require a different oil filter?
And what was Stellantis reason for changing the oil weight?
Thanks
