Couldn’t find this addressed anywhere else, so if it has been, please direct me to the appropriate thread.

I’ve heard that the 392 comes from the factory with Penzoil Ultra Platinum in the crankcase. Just wondering if anyone knows the actual difference between the “Ultra Platinum” and the “Platinum Euro”? Both are offered in 0W-40.

I’ve never been a big fan of Penzoil motor oils in general. Any thoughts?

There are probably different certifications in the fine print in each bottle, the one on the left in your post is for the SRT engines and the other certified for European cars. Now, other than the certifications, the oil may or may not be the same and it can get debated for pages here without clear evidence of a qualified answer. The Ultra Platinum is available on Amazon, I have not found it anywhere else.
 
I’ve never bought 0W-40 before and it does seem to be much harder to find, thus my question. Is the $54 for 6 quarts of the Ultra Platinum on Amazon about the best price that you’ve seen? I can’t seem to source it anywhere locally.

I’ve always preferred Mobil-1 or Valvoline to Penzoil and Walmart does carry the Mobil-1 in 0w-40 in 5-quart jugs (for around $26 as I recall). I may just run Mobil-1 unless there is a convincing reason to use the Penzoil.

Lots of opinions when it comes to motor oils of course. Any insight is appreciated.

You get the first 3 oil changes for free at the dealer. That's 15,000 miles or 18 months. It may become more available in the next year or so??
 
I have the same thoughts. All my vehicles have run Mobil 1 except my LJR with the straight 6, it started a rear main seal leak there. I have seen the Mobil 1 EU 0-40 but have already bought two 6 packs of the Penzoil, each for under $50 with taxes. The price jumps around.
 
These manufactures just love coming up with new viscosity formulations it seems…

My daughter‘s 2020 Toyota RAV4 uses 0W-16 motor oil. Really, 0W-16…

0W-15 and 0W-20 just weren’t sufficient I guess…
 
Just depends about your warranty. There are not a lot of brands that have been certified.
Like all thing’s 392…. Is it worth a few bucks not to do exactly the right oil or octane etc…??

How many of you guys are like me and would want to see the 7 empty quart bottles of the Pennzoil Ultra Platinum 0W-40 after a. dealership oil change?

I guarantee ya there’s more than one Jeep dealership out there that would be more than happy to dump in whatever brand they have handy non-synthetic 10W-30 into a 392 and call it a day.

I guess I’ll just make sure to verify up-front that they have the correct oil in stock before I show up for that first dealership oil change. I’d still like to see those empty bottles though!

Totally agree… I plan to stick with synthetic 0W-40, just curious as to whether to go with Pennzoil or what many consider to be a more reputable brand such as Mobil-1.

A good friend of mine rebuilds engines for a living and he tells me that after 30 years of doing it, he seen more residue buildup and/or engine wear in engines that have used Pennzoil than any other brand.

Now this is kind of an apples-to-oranges comparison, because he’s talking about non-synthetic Pennzoil. So I doubt the analogy holds.

For now, I will definitely stick with Pennzoil Ultra Platinum 0W-40. Just ordered four 6-packs.

I Understand more than you know. Last week I bought a jug of euro 0w-40…. Then realized my mistake and returned it…. Thought maybe it was the same…
 
walmart.com has 0w-40 for 8.93 a quart and free shipping, i looked all over here and no one had it. Went to dealer to get oil filter and they had oil in stock but was way more expensive than Walmart.
 
The parts department at my local Jeep dealer sells Pennzoil full synthetic 0w-40. Might as well stick to what the factory recommends.

It's been a while since I read about this topic, but the summary of all the readings I did...change oil at the recommended intervals and with the recommended viscosity. That's it. From what I can remember (I don't know if it's still the case) Europe has stricter regulations regarding engine oils than America.

This website has some simple information.


These certifications make those two oils different. A3/B3/C3 are Euro certs. Is that better? Maybe. Better enough to choose it over A1/B1? Maybe not

To quote and repeat what @Viking Jeeper said:

Car manufacturers have many reasons why they choose the oil they use and it's not a single or simple reason. Many factors are considered when making their choice: cost, contracts, availability, etc.

Good info. From reading this (and other) articles, it sounds like the U.S. and Euro. are almost identical formulations. As the name would imply, one is created for the European market.

Worse case scenario, if a guy couldn’t find any of the Ultra Platinum and had to do a full oil change with the Euro. version, your engine probably wouldn’t suffer significantly in any way.

No reason to preferentially choose the Euro. formulation of course, although ironically enough, the Euro. version of both the Pennzoil and Mobil-1 seem to be more readily available at big box and auto parts stores (lots of imports running around of course).

This is why I have Penzoil in my garage with 600 miles on my 392. I'm unlikely to use the free oil changes.
 
No dealer oil change is free…. My first of 3 “free” oil changes on my dodge truck cost me the oil pan as they air ratcheted the plug through the pan and had to pull the engine to replace the pan…. That was the last “free” oil change I ever got.
I’ve heard of similar nightmares with both dealerships and Jiffy Lube-type places.
 
I have never owned a Jeep (yet) but my F250 is high enough that it requires minimal effort to change it myself. I don’t see myself taking the 392 in to let someone that has no skin in the game change the oil and filter.

What dummy uses an air gun on an oil plug. I did on a car once, lesson learned.
