- Hemi 5.7
With the hemi, my opinion is to follow the noises of the engine. I know some guys go crazy with this, which is not my intention, we have guys so scared about hemi tick they think any noise is a sign. This was the downside of all of this talk.
But, I would run 5w30 redline as much as possible if it were me, in the 5.7 and 6.4. The most proven tick killer and guys with hemi tick have smooth engines that have lasted a decade in a lot of cases, including mine which was silenced in 2011, so soon to be a decade. Very low miles, but many other guys also came on board 2011 and 2012 with this strategy and knock wood so far so good.
The only time I would consider anything other then 5w30 redline (my opinion only on this) is if you get cold piston slap. Then I would go to whatever worked even 0w20 as long as I don't have warm idle tick and if possible kill cold piston slap. Also, don't forget the other options if you are in the cold, engine block heating or sump heating. I forget who put theirs in first but they both did it, kyle and corey, so how is it working guys?? hopefully they chime in because they both are in snow and both had cold piston and both had hemi tick.
According to Hammers chart 0w30 is a very short swing at the issue of cold piston slap, whereas 20 weight anything would be a larger one. If 20 weight keeps piston slap and hemi tick away but 5w30 has cold piston slap, I would use 5w20. I had good luck with 5w20 redline personally, I was one of the last guys to move to 5w30 of this group.
Either choice 20 weight redline or 0w30 comes with a risk, pick your poison. 0w30 redline has been a proven tick killer even in rams that ticked on 5w20 redline- IE corey's truck, proven and backed with audio/video, and also in his truck was "better" at cold piston slap. To be honest, he is the guy you should be asking. In theory one will be better at cold piston slap and the other one will be better at hemi tick. It's a judgement call, what works in Corey's truck might not work in your truck, what works in mine might not work in yours. Corey and I have had completely different results with same redlines. Hope you make the right choice and save yourself from wasting some oil.
Thanks for the response. I'm leaning with trying the 0w30 first and seeing how it goes. Also going to run my first oil analysis since I'm almost done on my second change of redline.
