0w20 more engine wear?

Remember duralube? The commercials where they used it then drained the oil, ran it dry and threw sand and water on it? I wondered what happened to it. Thanks google

https://www.ftc.gov/news-events/new...ers Dura Lube and,in violation of federal law.

Yeah.

People get all bent out of shape on the 5 quart, 6 quart thing. It’s not going to hurt a thing to add a quart extra. Now if you went two or three, then maybe you’ll have an issue. The 6 quart 3.6 could take 7 quarts without issue. If people were this literal with all the specs, then we wouldn’t have all of these wonderful oil viscosity or octane for the 2.0t threads. Lol.

So what is it about the super charger that ups the oil capacity? Is it oil cooled?

My understanding is the biggest issue is to pick an oil that meets FCA Material Standard MS-6395 for the V6. There are many weights and brands that meet that criteria.

From the owners manual for the 3.6: We recommend you use API Certified SAE 0W-20 Engine Oil,
meeting the requirements of FCA Material Standard MS-6395

For the 2.0: We recommend you use API Certified SAE 5W-30 Fully Synthetic Engine Oil, meeting the requirements of FCA Material Standard MS-13340

Notice in the owners manual it says RECOMMENDS but does not say REQUIRES. I am fairly certain 0W20 was picked because it offers slightly better fuel economy and is a 6395 oil. Also notice that it does not state fully synthetic for the V6 application, only for the 2.0 application.

The GDMFing FAD was added for fuel economy standards as well.

MS-13340 oils: can't find list yet

0W20 vs 5W20: https://oilsadvisor.com/0w20-vs-5w20/

I believe there is a Penzoil 10w30 that meets the spec also. Have just heard that Penzoil guys run Mobil 1 in their vehicles...

Per that list, Pennzoil Platinum Full Synthetic 10W-30 is supposed to be MS-6395 spec.

I'm out of warranty and have switched to Mobil 1. The Jeep seems to run better with it. 5w30 or 10w30, I forget. Hot climate here.

Mobil 1 finally changed their packaging sometime last year and the label finally says "meets or exceeds" the Chrysler MS-6395 specification, at least for their 0W-20 EP variant for the v6. It's not reformulated and has always exceeded that spec, but it wasn't until mid to late 2022 that FCA completed the testing and approved the certification (according to Jim at Mobil 1).

Shouldn't be any warranty issue with using it now, afaik ?

It's not oil cooled. It's mainly because the pistons don't have a blower ring and the case pressure is much higher, so there's more blow-by and more being pushed out the PCV valve. The extra quart allows it to always have enough oil throughout the oil change cycle. The consumption isn't crazy or anything, but it is measurably more.

Gonna run a catch can again?

Because from a psychological perspective, people like to feel in control of their fate. Rather than accept the reality that the random chance of the variation in manufacturing quality will determine how long their particular engine lasts, people would rather obsess about oil because it makes them feel like they can partially control the outcome.

Well I suppose people can, partially. But when you’re consistently ramming at 6K rpm trying to crawl up a rock ledge with engine temps in the upper 240° range, something has got to give. I’ve seen the videos.

Absolutely. It’s been on there since the blower install.

You do you. As for me I have the turbo, I love ripping sand at high RPMs and climbing rock walls which at times require a lot of skinny pedal. I'll stick to psychologically fooling myself into thinking that my 3k oil changes are worth it.

This thread was talking about oil weight, not mileage intervals. No need for psychology as to how often to change -- have your oil analyzed and you can get a clear answer.

OK fair enough. But weight does matter, if it didn't there wouldn't be so many.

A lot of it has to do with manufacturer changing things in order to meet federal mpg standards. Many questions have been raised as to if these changes come at the expense of longevity.

Look at all the issues created when try added the ESS to the JL. Take a quick trip around the forum at all the problems people have with the aux battery and the ess.

"they" also tell us the transmission never needs serviced with fluid changes. It's a lifetime transmission fluid. Yes, correct, and the lifetime of your transmission will be much shorter. Ask those who have had it changed hiw filthy it is at 50k miles.


All of this to say, the manufactures don't necessarily recommend the ideal maintenance or install the ideal parts. Regulations and costs always have factor in.

I just pose the question if it was potentially more damaging or not than alternatives.

Fair points you make, all of them.

But I don't believe that is the case with oil. Just one persons opinion.

 

[CarbonSteel]

Oils of the same viscosity will have more or less wear. Factual testing shows the Amsoil have the least wear.
The question is the reduced wear justify the increase cost and the hassle of mail order purchase.

Would love to see what ASTM or SAE test parameters were used to quantify that statement as well as the results. This would apply for any oil where a statement like that is made (not singling out Amsoil--though they are probably the forerunners for that type of rhetoric).
