Unknown Jiffy Lube filter.
3000 miles on RedLine HP 5W30 following JL's engine clean & flush service performed by previous owner prior to sale.

Loosened soot residue was dry and flakey. Had it occurred to me, I would have checked on and likely changed the filter after 1000 miles and every 1000 after until the oil reached 5000 miles.

Replaced with Fram XG8481 and Valvoline Restore and Protect 5W30.

Did they mention how long the cleaner was in the engine for? That is some very thick soot, I think I've ever seen on here.

No, it was just stated on the paperwork. Couldn't have been too long. It was a $59 add-on at Jiffy Lube. I think it is from the PAO in the RedLine HP.

Holy 💩💩💩💩💩

That is a LOT of gunk/whatever in pleats
 
I'm having doubts about jiffy lube ever changing the oil filter after running a flush through the engine. Redline oils are not known to actively clean engine internals. Glad you caught a glimpse of that loaded filter and changed it.
 
The oil wasn't changed in that 320. My daughter had a 99 and it ran great at 300k miles. It had Mobil1 0-40 its whole life. The first 160k had 8-10k oil changes and then every 5-7k miles. All the keys broke or quit working and she was down to one metal parking lot key. I think she lost that. She ended up donating it after letting it sit for several months. It used a little oil but ran great. Smooth and solid. They were the first MB sub's and were probably the best. You've got a great suv if you can rehab it. I wouldn't run it too long on R&P because that doesn't meet the requirements for that engine. 229.5 oil will clean that engine with short OICs.
