I recently purchased a new RXPX. I have excellent quality 87 fuel with no ethanol, and run this in my current RXP 255. I can also get 91 octane from a gas station, however this has some ethanol content. My 255 claims to require 91 octane, but has never had any issues since I purchased it new, however I was wondering if anyone has run a new rxpx 300 on 87? Any thoughts are appreciated.
