What will you be doing differently from the maintenance schedule?

[BoisetheCat]

Because Jeep says run 5W-20 in the same 3.6 engine in my JK. It's all for CAFE BS. OW-20 looks thinner than water and it gets really hot here. I'm not sure what I am going to use.

I wish that The GreatGrapeApe would give his opinion. He is very knowledgeable and I value his advice.

idk what to say to that. its been said countless times this pentastar is re-designed..

First, it is not the same 3.6 as in the JK. It has been significantly redesigned, with 0w20 in mind from the start. Secondly, check the flash point on different oils. Mobil 1 0w20 Annual Protection has a flash point of 468 degrees, which is outstanding. Compare that to, say, Pennzoil regular yellow bottle 5w30, which is 421 degrees. So, in that case, the 0w20 will give you the best of both worlds....fuel economy and high temperature protection. I'll be running Mobil 1 AP in mine, and will change the oil once per year. (Probaby 7,000 to 10,000 miles per year).

That flash point for 0w20 AP is even higher than the Mobil 1 5w30 AP, so when the 5w30 goes up in smoke at 450 degrees, the 0w20 will still hold together and have almost 20 degrees margin before it does the same. Folks, that's an amazing oil. That's why I'll run it.

dan what does that mobil 1 0 20 ann prot recommend for mileage intervals?

Get this....Up to 20,000 miles! Or, one year. Their best group IV base oil is in this formulation, and it has been tested to handle turbocharged direct injected engines, which are MUCH harder on oil than the 3.6, which has been shown to be very easy on oil. If I were to go 20k on an oil, it would be in this engine. (I won't do that.)

Good stuff. Great info. Just recently joined. Glad I did.

wow thats impressive. what is a decent plan you think? 7.5k? give or take a bit..

I'm going to do my first oil change around 2000 miles, or maybe 3,000. I'll do a used oil analysis (UOA) with Blackstone Labs, just to see how the wear metals look. They'll be pretty high because it is the break-in oil. I'll go straight to the Mobil 1 0w20 AP, and will do 5000 miles on the second run, then do another UOA when I drain it. I'll then see how the oil looks, especially the TBN level, then I'll go to once a year or when the oil life monitor tells me to change it. I won't exceed the OLM, due to warranty. However my money says this oil can be pushed beyond 15,000 miles with little worry, in the 3.6. Certainly 10k should be easy for it.

I'll publish the UOA's on the forum when I get them, so you guys can see what's going on inside the engine. I already received my kit from Blackstone. It has 4 bottles in it for 4 UOA's.

For extended oil changes, I'd recommend Fram Ultra Guard filters. The filter media is backed by metal mesh, so they are set up well for extended oil changes. They are also rated to 20,000 miles. Mobil 1 I think now certifies their oil filters to go 20k, as well. Overkill? Yes. For my $50k Jeep? Well worth it.

Exxon Mobil tested a Chevy Silverado with a 5.3 V8 on the AP oil, I think 5w30 (which doesn't have the etreme pour point or flash point of the 0w20) and ran it on 20,000 mile oil changes for 520,000 miles. They let an independent mechanic tear it apart and he said it looked no more worn than an engine with only 50,000 miles. They simulated a good bit of towing in that test, too. I believe they wore out a transmission along the way, as well, but the engine did just fine.

The Chevy 5.3, like the 3.6, is easy on oil, but it tends to have high iron in Blackstone UOA's. While that looks like more wear, in reality, Mobil 1 goes with the Chevy 5.3 like chocolate chip cookies go with milk. I had a 99 Chevy Silverado with the 5.3 and sold it to my secretary. Her family still has it, and has continued running Mobil 1. It now has well over 300,000 miles on it and has never had an engine issue. They went with the oil life monitor for oil changes, and it typically ran out to about 7,500 miles between changes. That's on oil not marketed for extended drain intervals. I've run all my engines since 1987 on Mobil 1. I've got high confidence in it. I've run 2 Jeep Wranglers past 100k on Mobil 1. Currently, I'm running Mobil 1 high mileage in my JK, at 121,500 miles. I go 6,000 miles on each change, again, due to warranty constraints. Otherwise, I'd take it out to 10k, no problem.

That's great info. thanks. so your 1st change is pretty early, what's the thinking behind this? just to start using the superior m1 oil earlier or a combination of things?

 

[Hughesonthenet]

Really basic question, not really Wrangler specific but...

With an eye toward proof of preventive maintenance on the recommended schedule, do you use the dealer, or do it yourself? If yourself, what records do you maintain to prove on schedule oil changes, etc.?

Dan pretty much covered this in his two posts. I have faith in the 0W20 at both ends of the temperature spectrum and for longevity.

I’ll just add my revised plan to the info.

I will still do what will be extreme for most people, and change my oil & filter by 1,000 KMs / 650 miles, but as mentioned before, that’s my expensive attempt to flush out residual mfr debris. Afterwards I will stick close to the schedule... although 20,000 miles is too far for me regardless, maybe 20,000KMs... but still... oie!). At even 20,000 KMs we’re talking about about a year’s worth of driving for me (or a few weeks in the occasional summer like this year), and I think in that case, I would definitely change the oil in the fall again if it needed it or not.

I know the FCA schedule isn’t that high but if it were to change to anywhere close to that, I think I’d still be chronological more than distance.

20,000 miles / 32,000 KMs would take most people about 2 yrs or 18months to do, so I don’t think I could let it go that long especially knowing that ~2 yrs worth of debris etc was collecting in the filter.

Myself, only because it more convenient. I can’t stand sitting and waiting at the dealer, and dropping off is a hassle. I would also never (again) use a quick change place.

I use Blackstone Labs for oil analysis, and use that as my proof (along with receipt for oil and filter).

A couple of years ago I bought one of these: Fujitsu ScanSnap iX500 Color Duplex Desk Scanner for Mac and PC https://www.amazon.com/dp/B01G3JYVYM/ref=cm_sw_r_cp_api_qR7CAb88ZQG3T

Life changer. Scanning receipts (and everything else) is sooo easy. I keep a folder for each car, kid, pet, etc. with all relevant scans, oil purchase receipts from Wally World included.

Same reason as Ape said. I want to get the crap that comes from break-in flushed out of the engine, but also as you said, to get the superior oil in there. Right now, I'm leaning toward 2,000 miles. I'm taking it up to Michigan in two weeks for a snowmobiling trip, so I'll put some highway miles on it pretty quickly. Weather also might make me wait a bit. 2,000 is the target, but it could slip past there. One great thing is that I don't have to stay under the Jeep for more than draining the oil pan and putting the plug back. No farting around with messy oil filters while laying on my back. That makes the change quick and easy. I'm looking forward to that.

Why no messy filter? Because you’re not changing it at 2000 miles, or because it’s located where you can reach through tire well or engine bay and not get messy? Maybe a dumb question, but this will be my first Wrangler.

Because it is a cartridge and I can get to it standing up. It is front and center on the engine. It won't pour everywhere like when you unscrew a can filter.

This is my first jeep too and planning to do all maintenance. i've looked at a lot of jk's tho and the oil filter is accessible through the engine bay in the jk, so i'd imagine the JL is the same

Yep. My JK, though, is a 3.8. The filter isn't in a bad spot, and is easily accessible, but I have to do it from underneath, and it does drip all over the axle housing. No way around that.

Hey, another plus I just thought of...The 2" lift and 35's will give me LOTS more room when crawling underneath to loosen/tighten the drain plug! Again, the JK isn't bad, but this one will be much better.
