Sensors malfunction and fail. Keep on being a miser, though. You're the type of guy who runs Motorcraft synthetic blend oil for the full duration of the computer indicated OCI just because it's "ok" to do so. I feel sorry for the people who buy your cars second hand.No we are talking about compression, and timing, and physics don't change. Honda also ran over 11:1 in an old Prelude and still ran on 87. High compression engines can easily run 87 if they are tuned for it. The fact the manual says that 87 is fine on our engine means it IS FINE, have a problem? It's a warranty issue, or bad tank of fuel. Not a "it's to high compression, you should run 91+ ignore what Ford says" issue. People used to think you HAD to run premium in the Taurus SHO v6 with its "high" 9.8:1 compression. Yet people still ran 87 and even 85 on that just fine. Why? Because it had properly done timing curves. It didn't even have Knock Sensors to keep it alive.
This isn't the 60's or even 80's or 90's and we have smart ECU's now.
