After oil change where I previously had 5W-30 with valvoline dino, I changed with a different brand 5W-30 (Peak brand). Ticking noise started immediately from engine area usually only after it got up to temperature. So I pulled out a quart from the diptube with my suction device and put in a quart of 10W-40. Almost immediately PROBLEM GONE.
Pros: problem gone almost immediately
Cons: ticking noise started immediately
