Base Number was a tick low but considered acceptable.

What was the previous oil on June 8 that gave you 7.23? Any changes besides oil/filter manuf. and weight?

Wouldn't their claims also be confirmed with the oil analysis done?
:LOL:

Sorry, you can attribute that to any number of things, including the oil he uses, the reduced miles between changes, HOW the thing is driven, the RPM and engine loading involved, the fact that some engines will just show less wear than others because of what we call a stackup of tolerances where some wear earlier than others, some will show the crosshatch pattern in the cylinder walls for 100,000 miles or more while for others it will be gone by then.
Way too many variables.
I have never had a startup rattle in any of my 3.6 engines, none of them. OTOH, I've had startup rattle in more of my other vehicles over the years simply because lash adjusters - lifters in other engines - may bleed down over time. How much is also a factor of many things such as oil, wear, temperatures, valve spring pressure, whatever.
I would bet that if every Jeep owner did an oil analysis, we'd find some others with the standard setup with very similar results.

For example, taken on a per thousand mile basis, some of my numbers come out awfully close to his - aluminum, for example, is identical per thousand. My copper is a bit less than his, my iron was higher, but all I can find at the moment is the analysis done at less miles than he has on his so I'd expect some higher results there as it was still in the low miles, breaking in period. Still, as the report said - it looked good, no worries, no alarms.

Is it a bad device? No - solidly made, gets rid of any chance of a brittle housing cracking at 80,000 miles, which is about the time many report they simply go bad. You can get filters pretty much anywhere, a bigger choice of filters, there are advantages to them. I don't talk people out of them, I see the allure, just don't rely on the marketing and the "dry start" stuff, or that it's going to absolutely prevent cam failure. There's no study, no data, to support anything either way, for one thing, cam failure isn't a given, and many millions of these go without a cam failure, all with the stock filter.
There is no way in the world to prove anything or disprove anything.
Do what you believe feels right - if you want one and it makes you feel better about it - go for it.

Plus the extra 1/2 quart of oil capacity.
Question for you on that............... 5 quarts, and that is an exact 5 quarts minus what won't drain out of a jug, puts my oil OVER full on the dipstick. It has done that on every JT I've had - 5 quarts means over the aluminum bit onto the cable itself, by at least 1/8" or more.

If you put in the 5 quarts, and an extra half quart (since these call for 5, and you say it adds an extra half quart capacity) where does it end up on your 3.6's dipstick?

Yeah, thats what I kinda guessed.
@Hootbro also making it not so easy because the oils:giggle:
I will likely change it before the plastic one fails 😇 2020 but with only 22k miles 😋

I talked to my sales guy, who drives an FCA vehicle with 3.6 and it has about 80,000 miles and he made a comment about how his oil filter/cooler just started leaking - no one had touched it for a while and he was honest - "it cracked and started leaking like most of them do at that mileage".
He came right out and said it - it's probably going to go just due to age. Sounds like they keep them in stock.

Hootbro keeps us on our toes, keeps us guessing, maybe one of these days he'll formulate - and write down or remember exactly what he did - some oil concoction that we can demonstrate is a real Holy Grail for these engines. But he keeps moving the target!

A 2020 with only 22K miles? Man, both of my Overlands had more than that when I traded them off.
Keep the miles low and documented and if it's still under 30K in 20 years, it could be worth some real $$$!
No, probably not..............

Nah, doubt it (also).

Pretty much already nice and corroded :D all doors and hood. Was meant to be a vehicle that gets used, not collected. We work IT and a lot of home office or 7 miles to the office. Also gets used for the dog training and going to the forrests, some search and rescue, as well as offroading. We still have a Grand Cherokee 2005 CRD, that was the vehicle eating miles :like:
I asumed the age plus heat cycles can't be that great. Will get a unit through family sent to us in Germany.

I do enjoy the mystery of what @Hootbro is cooking.
It also keeps the labs on their toes, as we can see if they catch things like the mixing :rock:

Stock, 5 quarts after waiting 5-10 minutes, level is at the top of the cross hatch section barely kissing the upper bulb part.

With the Baxter Performance oil filter adapter, 5 quarts lands right middle of the cross hatch section. With the recommended compatible size can filter, an extra 1/2 quart brings it right back to the top of the cross hatch section.

My drain time is also probably 30-45 minutes before I close it for refill.
