1st Oil Change

[Jeepstin392]

A little write up of the first oil change.

1. Completed at 3000 miles, 52% life remaining.
13mm drain bolt with the stamped steel oil pan.
Factory installed filter spun off easily with minimal effort.
Oil still had a honey color. Dirty, but still some gold in there.

2. “Oil Consumption”
I observed none. Drained and measured the discarded oil at 6 Qts 28 Oz. Assuming there’s some in the motor creeping around. Or, the 4 Oz. Difference from full was negligible. Still yet, expected due to initial seating if the rings to cylinder walls.

3. Oil Filters
The MOPAR SRT filter “MO-041” o-ring matched up perfectly to the stock filter.
The MOPAR MO-899 and the K&N 2010A, the o-ring is slightly wider set in diameter than the stock. I didn’t trust this, so I went with the SRT filter. It fits, no leaks, and allows for more surface area, less resistant flow, etc.

4. 7 Qt. Refill. I used Mobil 1 0-40 with Marvel mystery oil. Yes, I drank that kool-aid after a few engine tear downs that had used it religiously in oil and fuel.

5. Slightly cooler coolant and oil temps observed. Only 3-7° less, but a reduction nonetheless. I compared the temps on the same day, same conditions, etc.

6. Filter removal/oil drainage
Like many designs, oil will get on components. Such as the track bar and steering linkage. The factory steering stabilizer will harbor some drained oil from the removed filter. After a thorough wipe down, there’s visible drips specifically from that part (stabilizer) and nowhere else.
I left the little janky plastic oil diverter in place. Helps to direct the oil flow but I can see this possibly coming off.

I hope this helps anyone who’s looking for some intel.

Thanks! I have a stock filter and a 899 on hand and had noticed the gasket on the 899 was a little larger than the stock filter. I guess now I will have to find a 041 but so far no luck.

I have the same. I think the 899 should work better with the tiny bit of difference Larger? I’ll post when I do. Because I couldn’t find a 041 either, next time…

I wasn’t willing to risk it.
Take a close look at the filter seat. It’s tapered on each side of the gasket plenum.

I dont want to risk it either but every time I looked at Amazon the 041 was unavailable. I find it on a a few enthusiast sites. Ebay has it for $46. Actually they are out of stock at that price also.

899 worked on mine. Not a drop leaked as of yet. I didn't look close enough to notice the difference in gaskets..... it does look like some places have 041 in stock if you do a google search. I ordered 4 of them and will see what happens. Will post up if they ship or change to backorder.

 

[Viking Jeeper]

041 seems to be out of stock everywhere. My dealer says they can get me one by November. I have a 339 and a 899. When I have it on the lift I will take a very close look to see how well the 899 fits. I plan to change at 5000 miles so maybe the 339 will be just fine.

 

[hardhat]

My dealer can get the mo-041 oil filter for $35.........Ridiculous price.

There has got to be a better aftermarket oil filter out there. Mobil-1, Royal purple, amsoil. I saw mobil 1 makes a mo-339 and mo-899 replacement. I'm about to give up on the mo-041. I know I'm overthinking this and could just run the recommended 339.....the filter just seems tiny to me.

This is a premium vehicle and I would like to run a premium oil filter with a good anti drainback valve on it. Anybody weigh in on this....maybe we can do a little research and come up with a consensus on the best oil filter to run on here. I would run the mo-041, but $35 is crazy. Mobil-1's premium replacement filter is cheaper than this and I don't know if it is better or not.....

I'm gonna do some research when I get some time and will post my findings, maybe some others can do the same...... or if one of my fellow gearheads out here knows off hand, it might save us all some time.....

I order Wix 57060 or the bigger SRT Filter 57063. I have run them both and prefer the 57063 larger filter. They are available on Amazon if your parts store is out.

They CANCELLED MY ORDER..... backordered so far that they just said forget it....

Hey Jeepstin”I too am a fan of Marvel mystery oil did you go with 6 quarts of Mobil 1 and 1 quart of the mystery oil.
I’m getting close to 1000 miles on my 392 and am going to do it myself using 6 quarts of 0-40 Amsoil and a Wix 57899XP filter and 1 quart of mystery oil.I’ve been supplementing Marvel Mystery oil in all my vehicles for years I have a 1972 Pontiac with 260,000 miles on it and have added 1 quart of mystery oil at every oil change since I got it 48 years ago.I usually checkout the forum everyday and remember reading your post.

Hi
Thank you!
I am a little nervous to put in a full quart. I scale back to 24 ounces.
My thinking is just enough to reduce any deposit build up but don’t want to take away from the benefits of synthetic oils. I doubt the 8 oz. Difference truly matters. But it’s in my head.

Thanx Jeepstin392”I’ll also go with the 24 oz and see what I think after running it awhile.

Some discussion in TRX land about oil filters. I run the SRT filter because I was fortunate to build a stash...wish I had bought more.

*47* RAM TRX / HELLCAT OIL FILTERS CUT & COMPARED

To my knowledge this is the largest compilation of it’s kind as far as filters for this application. Obviously all of these fit the TRX as well as the Chargers, Challengers and even Hemi Rams (without EPS). This is not meant to be an argument for what’s best (although I’ve included a poll so you...

Great write up and suggestions! Do you think the first oil change at 500-1500 miles to be too early? I’m considering that since the manual says “…break in occurs mainly during the first 500 miles”….and to “avoid high engine loading…” in first 1500 miles.

There’s a lot of good info on this forum that’s why I check it out everyday. I’m going to go ahead and follow my brothers recommendation to (if you can trust your dealership)to just take it there at around 1000 miles and tell them to change the oil because your getting 3 supposedly free oil changes from JEEP Wave”. I’m going to just do it myself it’ll probably be closer to 1200 miles cause we took a road trip for Easter.by the way my brother is a mechanic and total gear head.

 

[SCARd4Life]

I changed all oils (engine, differentials, and transfer case) at 2500 miles on my TRX. Rear diffs, as reported by many TRX owners, have the most metal paste on the drain plug magnet. Plan to do similar on the 392.

I know the OEM fill has a blend that permits proper seating of the rings to the cylinder wall. According to many manufacturers and independent reviews,, putting synthetic in too early will contribute to the process not completing properly. That’s what I go by. Working for a manufacturer for the last decade+, I’ve learned there’s always a reason engineering performs certain tasks or set ups.

as you identified, that’s also why they say 500-1500. Various components break in at various intervals. Most of what I researched, the cylinder walls and rings are pretty much done by 1500 miles.
