When you hear it youll know. It sounds like a very very large sewing machine is under your hood.Interesting. I am not familiar with the "hemi tick".
LOL!...I love the last line of your post. By all means let's not have any difference of opinion on an oil thread...LOL!My choices are as follows:
(since switching to valvoline, the famous hemi tick disappeared in ALL my hemi vehicles)
1) Valvoline SynPower 5w20
2) Pennzoil Ultra 5w20
I only choose valvoline first because i`ve ALWAYS had great luck with it.
Years ago i use to use pennzoil until they had some issues with it sludging up, BUT,
like i said, that was years ago when that happened, pennzoil stepped up an fixed it.
I`ve used pennzoil many times the last couple years, never an issue anymore with it.
Either oil is plenty good enough to use with no worries today, especially being synthetic.
Its been a good day, now watch some dumb bastard come in here and fugg it up...lol
I have had the tick since new with three different oils, it's worse now running mobil1. Think I will try pennzoil ultra next. If this never goes away I will trade it in as I find a ticking new truck embarrassing every time I go through a drive thru.
