ah I get it so a UOA determines how the oils performance held up.
Long intervals are not meant for track use or gunning 24/7.
isnt synthetic oil supposed to keep its properties for a long time?
just gonna run it 8k.. T6 has high zinc which will protect bearings or so I've heard.. fuel dilution is not an issue because it's a 5w40 not 5w30 which is on the cap. I bet I could run it for 12k taking it easy and it would be fine. having a tune doesnt mean jack.
- over maintaining something...
im considering running t6 for like 8k miles in my WRX as my tuner did and the UOA came back good.
some guy said its a bad idea..
Someone else said metal particles get caught by oil filter especially at extended OCI as it gets clogged, and hence would not be detected in the analysis. i know UOA...
