daeron Posted March 16, 2007 Share Posted March 16, 2007 most of us have to run high octane fuel to avoid pinging, but you should run as low an octance as your engine will tolerate without detonation.. Pinging happens most under full throttle, at lower RPMS, under load. In other words, find a hill, drive up it in fifth gear, with the pedal floored. If your engine makes some strange noises and seems short on power, you are pinging, and you need higher octane. I cannot describe "pinging" any better than that, and honestly I wouldn't mind a better description of the symptoms myself.. I never knew what it was, until I found myself in that EXACT scenario one day and it thundered into my brain that if I ran high test, that "odd stumble" would be gone.. sure enough, I was right...

"pinging" happens at any and all RPMs. Run high test for best results, unless it was de-tuned by the previous owner. Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted March 18, 2007 Share Posted March 18, 2007 This is not a true RX. This is a GL turbo coupe which are fairly rare. You could get a coupe with all the same options as the RX but it wouldn't badged an RX but just a coupe. Subaru_styles has a G55 turbocoupe which is an RX but like I said, not a true RX...
