Pretty sure it was SM. 10w30 with 3.5-4oz of VSOT used. Oil change is 3.5 qts, no makeup oil added. Mostly highway driving, I’m pretty easy on it, but am not afraid to redline it. PP is 10.37@100 and using 74.6 for VSOT, the blend should be ~11.1 cst, so it held viscosity. With a small sump and cheap synthetic oil stashed up; I like nice round numbers around 5k OCI. When I went 6k+ before the HLAs started getting noisy – they like clean new oil it seems. Oh, and I’m using a K&N clone air filter on a home-made intake.

They only test Moly in the add pack??? I’ll have to try calling them to see what’s up. Previous analysis at 149k was by Blackstone.
