I run E85 in the summer and E10 91 octane in the winter. I read that if running straight E85, you want to cut your oil change interval (OCI) in half, which would be 3750mi. I did my last oil change with 5000mi on the oil, probably a 60/40 ratio of E85/E10. My oil analysis came back great, with a suggested interval of 7000mi. That almost the same as the factory recommended 7500mi with no E85! Of course there are a million variables involved in a achieving a proper OCI, and I guess the numbers don't lie.

Anyone else running E85 or part time E85, and what is your OCI?
