I took it through the rpms a few times to see what actually happens, and I didnt have any detionation or any problems of pinging either. I personally feel if your gentle to it youll be fine. Even acura states in a service news article it is okay for you to use 87 if only excessible and can use for awhile without seeing a problem other than egr clogging problems. Perhaps ill run 87 for 2 weeks and see what happens and review it every few days.

Maybe 2 weeks won't do anything long term to your engine, but why risk your investment like that for an experiment?
