3.6 l Engine Oil Type

[Caleb75]

I started off using 0w20 as the manufacturer calls for. I did a couple of oil analysis. I then read some articles about 5w30 being the optimum weight for the majority of all water cooled automotive engines. So, I switched from Amsoil 0w20 to Amsoil 0W30. Then I had another oil analysis ran, my wear numbers went down. I eventually, put Amsoil 5w30 in and haven't looked back. My wear numbers are lower using the 0w30 and 5w30. No issues with the engine. I use Amsoil because I tried it, I liked it so I started selling it. I have it in the Jeep from the motor to the differentials and every where in between.

How can you be certain that the wear numbers aren’t lower because the engine is simply getting past the break in period?

I just changed to Penzoil 5w-30, full synth, for the first time. Around 25,000, and I am tire of the engine clatter, when fully warmed up. I immediately noticed the engine was quieter., after the change. Then again it is always quiet after a change. Time will tell.

I am certain some of the first analysis wear reduction was due to the final break in period but half of the oil analysis were done after 20k miles. It was a impressive difference the first analysis going from 0w20 to 0w30.

Well the good part is that they're not up. The naysayers will always find something to pick at. In the end, the quality of the oil will be the determining factor. Added Viscosity will just provide some temperature/load buffer.

I have a 2021 Grand Cherokee with a 3.6 and use only 5W-30 like my 2.0L JL uses.
On Avengerforumz in 2013 a FCA engineer mentioned to use 5W-30 in the 3.6 V6.
He said going to 0W-20 was a corporate gas mileage move and 5W-30 provides more protection.

One of the lead Pentastar designer on BITOG said use 0w20 and gave many reasons. And remember, the famous 625k mile Pentastar did it on 5w20, which at operating temp is no different from 0w20. I think you'd be fine on either, but I'm going with the 20 weight. I had a Ford F150 that is at about 200k with its current owner. All on 5w20.

That said, 5w30 is barely thicker at operating temp than a 20 weight. Should be fine.

There was nothing scientific in his tests either and the people on BITOG that debunked are far from ignorant. Exactly what in your UOA has shown that M1 has poor performance and coincides with Rat's findings?

Sir, 99% of BITOG members including their moderators are trolls. I wouldn't trust a thing they say. I think the website receives fat checks from companies like HPL to speak good about them. My VOA of HPL 0w20 has over 20 ppm of Aluminum, Blackstone said don't use that bottle. HPL is snake oil, horrible quality control. I will use nothing but Pennzoil and Mobil 1 going forward

Scamsoil, no thank you. Scamsoil dealers are worse than car dealership salesmen, a bunch of pushy crooks.

Using AMSOIL is never a waste of money. In addition to extending oil and filter change intervals, AMSOIL has been shown to improve fuel economy saving money. "AMSOIL Signature Series Synthetic Motor Oil provided 75 percent more engine protection against horsepower loss and wear than required by the industry standard, extending the life of vital components like pistons and cams." "Signature Series Synthetic Motor Oil achieved 100 percent protection against LSPI1 in the engine test required by the GM dexos1 Gen 2 specification - zero occurrences were recorded throughout five consecutive tests." "protecting the turbocharger 72 percent better than required by the GM dexos1®Gen 2 specification." It also provides 90% better protection against sludge in the Sequence VG Engine Test. Limits oil consumption with lower volatility. Easier cold starts. Allowed only 0.1% of the allowable viscosity increase in the Sequence IIIH Engine test Chrysler* 3.6L Pentastar* engine and 40% cleaner pistons than required by the standard. AMSOIL products also have the best warranty in the business. More information on the above at https://amsoilcontent.com/ams/lit/databulletins/g2880.pdf?zo=1181889 .

I'm not aware that Project Farm has performed "4 ball tests". Please provide the link. Also provide proof "Dawn dishwashing liquid will perform as well as motor oil in that test".

This may come across as the wrong way, so apologies in advance, but...

This is more than laughable coming from you, who changes his mind about what oil, what oil change frequency, and what oil filter to use more than the wind changes directions in a 24-hour period.

While there are some trolls on the site, the moderators there clear them out quickly, and I can easily say the vast majority of the members on BITOG are more knowledgeable about oil and oil related topics than the vast majority are here.

You would likely be ridiculed beyond belief if you posted on that site what you do on this one. You could learn so much about your favorite topic on that site.

Last, but not least, you need to change UOA companies. The last time that I checked Blackstone is not ISO 17025 certified, does not use all of the latest ASTM testing methodologies, and uses a highly subjective flame test versus gas chromatography for fuel dilution. Their "notes" are anecdotal and typically very amusing.

He WAS a troll that was banned from this site...

I change when I learn. I learned that HPL's quality control is horrendous, they look like tree shade blenders. Despite that, the dishonest BITOG people keep pushing it.
I resigned from that forum, asked them to delete my account. Too many trolls and the mod himself acted like a troll.

Not sure why I am going to ask this, but...

What objective and third-party verified proof do you have "that HPL's quality control is horrendous"? I hope your claim is not based upon a single Blackstone VOA. I have not used HPL and have no horse in the race, but that is a highly speculative claim you are making with nothing to back it up.

As said, I am sure that you would be ridiculed on BITOG and it sounds like you likely were which can come across as trolling. However, there are many tribologists, engineers, and statisticians on that site that 1000% know what they are talking about--which is likely 1000% in disagreement with your perceptions.

So Blackstone is wrong and HPL is right? The VOA was done next to two other oils, the other two looked normal. It was HPL with over 20 ppm of Aluminum.
Also, tribologists and engineers don't have that kind of troll language. Those guys don't even have basic decency, no wonder threads get closed all the time. They say that empty vessels make the most noise, they are empty vessels. Real engineers have better things to so than to troll around on an online forum.

Believe what you like...in all of the posts you have made here, little has changed your stance.

You need to learn what a VOA/UOA can and cannot do. If you were basing the quality of an oil on a single VOA then you are drawing a completely invalid conclusion. You need other third-party data and MUCH more in depth testing to validate your claims about HPL or any other product. A one time $40 oil analysis from a lab that is neither certified or uses current ASTM methodologies is NOT something that I would use as a basis for anything.
