Not to get into the constant oil debate...haha but I was wondering if everybody was shortening their oil service interval if they were using e85 here and there. Thanks in advance.
I would shorten it up if it's not a daily driver. E85 is hygroscopic and you WILL have moisture (like way more than normal) in your crankcase if you aren't getting the motor hot every day. I go 5000 on normal DD oil changes, I would go to 2500-3000 on straight full time E85, however, I recommend running 93 until you need E85, like going to the track. Treat it like race gas, IMO.
