So I accidentally filled the tank with 87 octane gas (I think, but need to find my receipt to verify). So now what do I do? I put in about 10 gallons with Stabil to top it off for winter storage. Do I have to drain the tank? Or can I get away with adding a bottle of octane booster? My ZL1 says Premium Required (not recommended unfortunately for this instance).
