2017 Porsche Cayenne w/3.6 VR6 - 81830 mi
At 4300 mi/half year into a run of HPL PCEO 5W-30 Euro and completed a oil filter change yesterday. Like many others here it was catching crud, and I'm happy a new filter is in service.
Back story: Bought the Cayenne w/55k mi and it consumed oil at 1qt/4-5k mi - not a concern for me. However, after changing spark plugs at 74k mi, the consumption started to increase, and it used 1.5-2 qts in 3400 mi ahead of the change to HPL. Also, it began making a mess around the oil fill cap, presumably from blow by. Previous oil changes on my watch were a couple different flavors of liqui moly and redline, all good VW502 rated or recommended oils. Checked the PCV and it was working properly and not showing the typical symptoms of failure. My diagnosis was oil rings were gummed up. There is not a lot of info on it out there that I could find for the VR6, but it's common enough among VAG vehicles.
After changing to HPL it consumed 1qt in the first 1000mi. As hoped, the past 3000mi I've only had to add 1qt. Also, the oil fill cap is not an oily mess anymore. Exhaust tips are less sooty as well nowadays. Looking forward to further improvements.
Pictures:
A little grit in the filter cap:
Dirty housing - previously, it has been super clean when not using HPL
:
Cleaned housing - please be forgiving of this cleaning job, the pictures don't illustrate how poorly accessible the housing is. I got what I could.:
filter did some work:
Filter is wrapped in paper towels and I'll cut it next weekend for a better look.
