My v6 runs terrible on 87 but of course it does because it has a premium gas tune in it. Like Chibi mentions up above the low octane tables are horrible. If I put regular gas in the car runs so bad you never put it in again.
My Subaru calls for regular but there are times I can hear it pinging and pulling timing. you can feel the reduced power. The Camaro on the other hand just flat out won't go it pulls that much timing on 87.
