Switched from Blackstone to OAI for this sample. I forgot to tell them the previous fill of Castrol Edge Euro 0w-30. I'll be sticking with Mobil 1 ESP 5w-30 going forward. Car has catless downpipe and currently on MHD stage 2 e30 tune.

I finally got my second report back from OAI. Currently running MHD Stage 2+ flexfuel tune. I usually mix to e50.
