May not run as well, but how long will a tankful last? Really.

Don't sweat it. Treat it to some 91 octane the next time around and she'll forgive you.

 

I always run 93 in my bike but was riding in maine and could only find 91 didn't think it would make much difference but boy did it ever run like **** i couldn't give it more than half throttle without it pinging real bad.

 

Best advice was already given. Ride it out and don't lug it. Had to use regular several times. Out West, sometimes just finding gas is a pleasure. If you have an octane enhancer, use it, but you don't need it. The ECM will pick up the difference and correct some.

 

Run it and don't worry about it. At least you didn't screw up like me. I am so used to hitting the premium button for the bikes, I pulled my Ram 1500 up to the pump the other night and hit premium, a $100 later and it still wasn't full. DOH
