That's how we roll at ram forum, everyone has some value to add. Huge development from another ram member that has transformed everything we know about hemi tick, I would encourage you to read last ten pages of sun thread, and pay attention to uncle tony's video.
So yes RP/Amsoil ea filters are still in favor with me, and so is 5w30 redline in warm regions, but I defer to
@Hemi395 and
@U&A for cold state testing because of some piston slap issues first validated by ram member Justin and then confirmed with these two guys.
So I believe 0w30 redline would be the ticket, and as long as that keeps the tick away, I'd run that all year. If you are on a twice a year interval, 5w30 in summer, 0w30 in winter. Regardless of tick condition this is now what I recommend simply from what I've seen in uncle tony's video. These hemi's need the types of things in the redline formula whether they tick or not. Those lifters have perpendicular force, as in all of them, so high moly at a minimum and ester will be more then helpful. Ask q's anytime bud
