Run what you like or what's available. Yes, there may be issues, but then again don't know until you try. IMO, ethanol blends aren't as damaging as when they pulled the lead out of the gas. Yes, seals MAY dry out and leak. However, running up to a 10% ethanol may or not be an issue.

I personally haven't had a problem with it, unless it was a 30 yr old seal that may have been marginal at best. Aftermarket vacuum caps however....
