Don't run 87 in it for much longer. The compression ratio on these cars requires high octane. The knock sensor is also very rudimentary on these engines and does not pull timing like a modern car. You can have pinging/detonation and not even hear it in the cabin. Will it cause catastrophic damage in the short term? Probably not. But long term engine health will be compromised.
