I have a Ford Asspire lol, that also pings unless I use 93octane. I checked the timing but can't rely on that because someone may have changed the timing belt and was off a few teeth. As long as I use high test, it's fine. Better power too for a 1.3L. They may have advanced the timing for that reason. Little thing has no hp stock. I figure they squeezed out some more by advancing the timimg.
