wow, that's new to me, ThX Neo...

edit: btw i really dont see it being harmful for the engine to use higher octane, but a huge waste since there OEM ignition system is pretty weak, the lower octane can help deton. occur at the right time. I only see octanes really mattering with huge compression ratios and F I'd vehicles where the cylinders have enough pressure inside to get knock...
