Yep, it was the best performer in it, with no consumption between drains and fills. It drank Amsoil AZO 0w-30 like water, which was bizarre, and that was over multiple test OCI's to see if the consumption would go down. I also ran M1 5w-20 (once), Delvac 1 5w-40 (twice) Duron-E 0w-40 (twice), M1 0w-40 (twice) and Pennzoil Ultra 5w-30 (once) in it. All other OCi's were M1 AFE 0w-30.
