A 10:1 compression ratio is relatively high. 87 octane fuel is not sufficient to prevent detonation (knocking) at that compression level. Detonation can severely damage your engine, potentially leading to cracked pistons, damaged connecting rods, or even a catastrophic engine failure. You'll need a higher octane fuel, likely 91 or 93 octane, depending on the specifics of your engine, climate, and driving style. Consult your owner's manual or a qualified mechanic to determine the appropriate octane rating for your specific setup.
