Funny enough I am going through the same discovery process atm. Going through allot of the forums, youtubers tests and keep finding that 8100s seems to have the better anti wear properties across the range
I wish I wish i could get the X-Cess Gen2 5w40 here as its a nice medium between their 5w30 and 5w40.
Eg. Project Farm, youtuber and found that the testing method is iffy, doesn't produce the same results. His choice for winner is kind of off as he only takes the mass loss not the % of starting mass, and the reported oil specs are grossly incorrect.
The metrics, with % values.
Look at that % diff for Pennzoil between the 2 tests
Anyways the link where i pull the stats from.
Did have a look at other youtubers and it seems a tug of ware between Motul, LM and Ravenol. The oil type they choose from the brand (version ie. x-clean vs x-max, ect) does seem to make a huge difference.
