My 2008 LTD AWD [17k] has never, ever whined fwiw...

I've got the same problem with an 08 LTD AWD here in Austin. My neighbor bought an 08 LTD FWD at nearly the same time and we have roughly the same mileage [16k/17k], but the neighbor's engine purrs like a kitten while mine pings/ticks like crazy. It's worse at a cold start [its hard to say 'cold' start here in Austin anytime of year, considering I lived in Minnesota for two decades], but continues to ping/tick like my old 81 F100 at 90k, and my old 88 Bronco at 110k, in sub-zero weather. I can understand that this type of engine may have some ping/tick issues as mentioned in the manual, but why do only some have persistent issues [as mentioned by others above], while others do not ping/tick at all [like my neighbors--we start them up together side-by-side, sometimes a couple of times a day!] ? I recently also had a 08 LTD FWD rental [9k] in Chicago that also had no ping/tick compared to mine that is persistent. For what it's worth, only Shell 87 octane has ever been used and has been maintenanced as per manual ... I would love to hear if others are out there with this issue, or how it's been resolved.

Maybe, Im curious...what are the effects ? [08 LTD AWD]
