I wouldn't worry about it. They recommend 93% for efficiency but it should be ok


It's not critical. The computer will adjust timing, etc to compensate. Switch back to the recommended grade at your next fill, or if it makes you feel better you can blend in a few gallons after you burn off some of the 87.
