Some how or another I did a quick search on here a while back and messed up and bought RL 5w-20 from Nick . Would it make sense to order 5w-30 and maybe substitute a few qts of 20 with a few qts of 30wt to create a mix . The truck is always in a heated garage , maybe gets 3500 miles per year here in Jersey . I do have a tick almost every start up if sat for an hour or so with Pennzoil synthetic 5w-20. Im due for a change by my standards not Rams gauge and figured I would ask the experts before I commit to all RL 5w-20.
I had 5w20 kill my tick, which was a bad tick. Oddly enough, it seams like the worse the tick is, the additives are all that matters, and that pressure will likely plate and kill the tick.
Now, guys like hemi395 as recorded has lesser ticks, well then 5w30 is key. From the little you said, my guess is you would land in this category. Less pressure ticks seam to respond to additives and viscosity, and 5w30 redline is the gold standard.
I'm not in like with your thoughts of mixing, or just using the 5w20, and here is why; because when someone first gets tick they get frustrated and they really want to hear a result. It doesn't mean you wont use the 5w20, because you will, but I'd rather give you best chance to kill the tick first before you start playing around. The hemi395 example which has been a phenomenal help to the forum, showed that in some rams 5w30 or 0w30 kills the tick, and 5w20 doesn't, but during the 5w20 run the tick is substantially better, just not as good as 5w30.
So here's another thought, is that a cold state? I know you are near water which usually means no, but do you see low 40's? One thing about 5w20 is it is prefect to avoid cold piston slap if possible. So you can make an argument to just go for it since winter is approaching and it will be cold soon.
I hate that it gets this confusing trust me, but we have witnessed in cold states stuff gets complicated. The sun belt ram owners just need to nothing but 5w30. And part of me is geared to try and get guy on one weight of oil for year round service if possible. Thanks to the work of hemi395 and others, we have found out that 0w30 redline is almost as good as 5w30 at tick killing, but way better at avoiding cold piston slap.
So if you are asking what I would do if I were you, one man's opinion, shelf the 5w20 just for now, we will come up with a plan later, but go get you some 0w30 redline and a RP filter, and maybe wait til it get's cold before you change the oil. As for what to do asap, go get some lubegard biotech "poor man's redline" and dump it in asap. I say wait a bit for 0w30 because the oil is at it's strongest at stopping cold piston slap or hemi tick when first used and vii's are at full strength. In cold areas guys need to realize this, the greatest need is to have the freshest oil in the cold, not the summer. If you oil is 2 mos old when winter starts, your oil will simply not have the same cold performance as if it was fresh oil.
Just a suggestion, you can make an argument to just go for it and use that 5w20.
