Silicon up a bit since previous test. Fuel is there & visc is still reasonable. 1/2 qt of added oil is great for 7.5k. Quite a chunk of Magnesium & Moly in this HPL 5w-40. Not a bad run but double check the air filter box unless this is an anti-foam HPL additive? 2 more PPM on the silicon & it would have been triggered. Thanks for sharing!
