Brad Penn says; As a matter of fact, the issue is compounded when used oil is left in the crankcase during lengthy cold ambient temperature storage conditions. Our BRAD PENN®
Penn-Grade 1® High Performance Engine Oils should not be considered for use with E85 fuel. Prior to the very latest PCMO ILSAC GF-5 / API SN (Resource Conserving) classification, most motor oils were not specifically designed to handle E85 fuels.
As flex fuel vehicle (FFV) manufacturing is expanding, so is the range of available ethanol-containing fuels. As you may know, (FFVs) are capable of operating on gasoline, E85, or a mixture of both. The latest ILSAC GF-5 /API SN (Resource Conserving) specification addresses improved rust protection and emulsion retention with E85 fuels. Since alcohol fuels tend to attract and hold water, motor oils meeting ILSAC GF-5 / API SN (Resource Conserving) are formulated to prevent phase separation (free water) of the crankcase oil due to fuel dilution. The technology developed for ILSAC GF-5 / API
SN (Resource Conserving) engine oils was designed to prevent both premature and catastrophic
engine failure by keeping oil, ethanol, and water in one phase.
Bottom line….we recommend motor oils meeting ILSAC GF-5 / API SN (Resource Conserving) requirements for FFVs utilizing E85 fuel.
Im currently running amsoil dominator 10w-30 on 100% E85 and will be submitting my UOA is a week or so.
Another popular oil is rotella. AND its CHEAP! but it only comes in a 10-40.
E85 dissolves cork and corrodes brass, neither are in our fuel system. A factory flex fuel system uses the same fuel lines as us. I dont know about the stock pump, but e85 doesn't play nicely with a few aftermarket pumps. I've HEARD aeromotive pumps are not recommended with e85. Walbro 485 works great.
There are a few on here that have been running E85 for thousands of miles with no issues but ill let them comment.
As far as water in the oil goes if you run an oil cooler on the street it should be thermostatically controlled and i always support a VTA catch can. That should help with moisture in the crankcase. Now moisture in the fuel system is a different problem. So far i havent had any issues.
