I was using the 10W-30 Valvoline Synthetic or Mobil 1 Synthetic with wix filter. After recommendation I switched to Valvoline 10W-30 dinosaur oil with quart of Marvel. The noise seemed quieter at first but came back just as loud. I don't think it's detonation because the sound is only there initially, goes away, and come back when warm. I don't think the lifter tick is very mild... The car has been going through some weird problems lately too. The headlights stopped working although sidemarkers still come on. The interior heat and ac control pod lights are working poorly. The lifter tick. Just a couple weird things like that.
