I can say with over 60,000 miles on an 18 LT2 2.0t I have only 91 octane a hand full of times. We get around 23 mph on Chevron 87 octane at 70 mph. I had spark plugs changed at 50k and they looked good a little sooty that I was told from running 87 octane. But plugs easily would of gone 60k no. That's my experience. On 87 Oct I raced a small BMW SUV and all he saw was equinox taillights. At 100 mph I started running away from him. That's my experience with 87 octane.
