6 Month Oil Change Interval

[albdriller]

Yup, page 298 from the '24 owner's manual. And the maintenance plan from 299-300.
Read your manual folks. Glad you did!

That settles the issue. I do think that this could be a dealer notification recommending the first Jeep Wave oil change right away or soon after delivery. I'm a big proponent of a first oil/filter change at or before 1,000 miles.

Regarding the frequency of these oil changes, I'm beginning to wonder about the quality of the components in these engines.
As comparison to an engines of similar HP, my F-car requires oil change at 3000 miles or one year. That car has an engine of 4.3 Liter, about 262 Cu, in, and 486 HP, with a recommended shift point of 8500 RPM. Obviously much more highly stressed and our 392s.
I hope I'm wrong, but a 6 month oil change requirement seems to indicate poor quality components to me.

I do not think it is a Toyota 5.7 or a 2JZ-GTE engine. As far as being as "forgiving" on slack in maintenance. Best we can do is follow the maintenance schedule.

All this oil change talk is good. Made me take mine in yesterday to get my 2nd free oil change (+tire rotation) at 7,400 miles. The oil life said 35% Remaining, but after our 2,200-mile trip to Moab last month, I figured it would be prudent. I changed fluid in both front and rear differentials before going to Moab for good measure.

These guys at the dealership changing my oil makes me uneasy. Last time it was here the case of oil was sat on my fender and put scratches all over it.

Yesterday they asked me how to open the Rugged Ridge hood latches. One guy asked me if the exhaust was factory or not. My engine skid plate slowed they down a little, but they figured it out. I guess they don't see too many 392's. I give them a piece of paper with the Tire Rotation sequence, but I watch closely to make sure they did it correctly.

Thanks for the rotation chart. Damn good looking 392! It looks like the techs are trying to figure out why your 3.6 has swollen!

Its a good idea to have a plan for tire rotation but the pattern used is not important, just that the same one is used each time so at the end of their lives all five have lived at each of the 5 positions somewhat equal time.

 

[OldVetteGuy]

Bottom line, make sure you update the Jeep app everytime you change your oil or visit the JiffyBoob location as the Stellantis Grinch will just off your Warranty if you don't. lol

When I use the have the dealer rotate the tires I'd use some chalk and put marks "LF" "RF" "LR" "RR" "SP" on the tires to identify their original location so I could figure out what they actually did and try and keep it in sequence. Now I just rotate them myself and put an "owner" service entry in the MOPAR website. By the way if folks don't have a torque wrench yet i really like my ICON ½ inch 40-250 lb. Split Beam Torque Wrench. It's accurate, dead simple, and perfect for things like Jeep tires where you need leverage for a 130 lb. setting. I've got a couple fancy digital torque wrenches that cost 5x more but I reach for the cheep simple ICON split beam when I'm doing tires. A Milwaukee 2967 ½ impact makes it almost fun.... almost.

I still have the dealer do the oil, it's not that hard and they don't charge that much. I use a $20 off coupon on the MOPAR site available here and it's usually $125 out the door with tax for Pennzoil Platinum 0W-40 SRT oil and a MOPAR OEM oil filter.

Retired driller of 35 years. I've dealt with dealerships for most of those years with our company trucks—nightmare stories of damaged trucks. Body damage, loose filters and drain plugs, improper greasing, I've even had a dealer employee take my truck home. Another time, I watched a kid run my work truck into a bollard while I was picking it up. Now I have the most expensive vehicle I've ever owned, and the thought of handing it over to GenZ or millennials for service is not my favorite thought. I do most of my own work, other than major drivetrain or software issues. I'm tossed on the free rotations and service. Thoughts?

I think you have your answer.
I personally don't care if I have free rotations and oil changes. I'm not taking it to the dealer for primarily the same reasons you described. I don't trust them. This vehicle is too expensive to be swayed by a "coupon" worth a couple hundred bucks just to have snowflaked children with green hair fling their disrespect and "don't forget how important I am" excuse of a work ethic around my rig.

end of rant...enjoy this wonderous gift of a vehicle.

I have always been a DIY guy for most, if not all, my own oil changes, repairs, etc. I had 4-free oil changes with my RAM (new from Texas-they get 4-free, not just 2) so I gained a comfort level with letting the dealership do it. So, when the 392 joined our fleet, I figured I would take advantage of those 2 free oil changes. Now I'm done.

From here on out, I'm back to changing the oil/filter/tire rotation myself. We have 7 vehicles, so I'm pretty proficient at doing my own maintenance. My retirement gig will be mowing the yard, washing vehicles and changing oil...HA!

Great Answer! Thanks

 

[OldVetteGuy]

Great Answer! Thanks

HaHa, we all have such great confidence with the experts at our local Jeep to do quality work. NOT!

If Jeep wants to do us a real favor, offer to give us the oil/filter and let us do it ourselves if that's what we want.
They save the labor cost, the oil gets changed. It's a win for everyone!

Ok, so having read this thread, along with others, including the thread where the guy lost the engine at 2k miles, but was past the 6 month interval, so no coverage from the OEM.....what about this: With the new Moab 392 pricing structure, and a good number of leftover '24 and '25 392s, what is a prospective buyer to do when all that are on the lots that are older than 6 months are in breach of the warranty requirement, so would a new prospective buyer, such as myself, be SOL when it comes to any warranty coverage on one of these leftover 392s? Or does the 6 month clock start when I take possession? If the latter, is it unreasonable to ask the dealership to change the oil before leaving the lot to get the clock started?
