What is the best way to rid the crankcase of oil that has been diluted with E85? I am working on getting the tune straight on my car after going twin crew and E85......incorrect tunes have caused fuel to really contaminate the oil. I will drain the oil before any sort of driving, but should I change the oil twice or just once? Just want to know the best way to rid all the contaminated oil before I strap it on a dyno and run it through the rpm's?
Thanks
