This OCI was Mobil 1 5w30 with a PUREone filter, it was put into the car in October and just changed out this past week (the car was garaged from the oil change until April). This car's only purpose in life is autocross and it gets drove rather aggressivly at any other time as traffic permits. This is a Turbocharged DI engine running 340/290 tq/hp (vs 260/260 stock) on the GM performance tune.
I was surprised to see the low fuel dilution since I let it idle alot during events to cool the turbo. Everything else looks good.
