OZ AKA Fleece tuned Cruze 2.0 Diesel with the Opel A20 DTH engine and Aisin AF40 automatic. 200 bhp and 320 lb/ft. Fuel Economy averages 38-41 MPGs per tank on 18" wheels and 225/50R18 Z-rated tires.
Slowly pushing this oil to 15k miles is my goal. Always with AcDelco filters.
-Silicon is likely from the oil pan RTV re-seal after the oil pump pickup seal was replaced with an aftermarket solution. The pickup seal failure is common and will kill the engine. Major design failure by GM on an otherwise awesome powertrain.
-Manganese and low soot @ < 0.1% is from Amalgamated TDR-FL. This tune burns super clean with quality CARB diesel + additive.
Viscosity increased, interesting considering the oxidation value is the same as the virgin sample.
Otherwise, boring UOA.
Refilled with RLI Biosyn HD SHP SAE 30, next sample in 14K miles.
