I did several searches...but here's my question. '99 Trooper just hit 100K and valve ticking becoming more noticeable. I will try Mobile 1, but not sure if I should start out 0W30, 5W30, or 10W30...or if it even matters.

Reason for my question is the hot, humid climate here and several posts I read about TSB and starting off with 0W30.
Thoughts anyone?
