I have a 2003 Outback 2.5 4-speed purchased new in Los Angeles that has had pinging problems since new. Not bad at all in cold weather, but starts knocking above about 60 degrees. Car is now in Portland Oregon. With windows up it is not that noticeable, but windows down - WOW! It's warming up here, so I'm headed to another dealer tomorrow to see if they can troubleshoot it. I have always used 87 octane (various brands) and the last dealer said to use 89 or 92 - whatever stopped the knocking. It did help, but I think that's crap - one of the reasons I bought this car was because it's a 4-cylinder that's supposed to use regular gas. I'll report the findings when the dealer is done with it.
