E85 oil change interval

Yes, I searched and came up snake eyes. Is there a consensus on how far to go between changes using E85. I think I saw 3000 written somewhere but not certain. I'm about to drop my 0w30 Mobil 1 at 4,000 and get analysis, but I just started using E85 so all that will change next time.

It's deep in one of either the E85 or OFT threads here, but some have recommended more frequent oil changes because the E85 can thin the oil.

Others have supposedly gotten Blackstone reports that show they're good to go for normal intervals. So... who knows?

You should be fine for regular interval if you use API SN Resource Conserving, which is formulated for use with ethanol
