Sent in another sample out of curiosity. This sample was with Castrol Edge 0w-40 with 3k miles, but was in the crankcase for over 2 years. The FiST is clearly not my sole means of transportation. I’m planning on wringing the motor out soon and felt it would be best to have fresh oil in there and not risk it. Good to see the results with Titanium, Magnesium and Zinc in the additive package.
