As the title says I added 8oz of MMO to the crankcase last night. I have been using the recommended dose in the fuel over the past couple of weeks and just decided to experiment with it in the crankcase. I only have 1000 miles to go on this change so it won't be in all that long. BTW, we are talking about an 03 Neon 52k miles. Anyone else use MMO in the oil?
