Wondering if anyone else has experienced this. When I change my plugs in the spring for the season, I hand tighten them in, then give them another half to three-quarter turn in to tighten them up. By fall, they're loose enough that it only takes about an 1/8 turn or so to bring them out by hand.
No performance issues found at all. I just wonder if these motors are seriously turning the plugs back that much - or if it's just warm motor (new plugs installed after warming up for oil change) vs. cold motor. Next year I'm going to index and count the turns on a few plugs for documentation later in the season.
