5.7l hemi oil.....

I think the hemi is easy on oil-- 7 qt. sump and an engine that lopes along at 1500-2000 RPMs most of the time. I believe most any oil will perform well in the 5.7 hemi--I currently use Valvoline RP 5w-20.
Which is NOT recommended in the manual for that vehicle.
Since I'm the one that paid for it, I'll run what I choose.
How's it run on the Valvoline Restore and Protect ? Notice a difference?
If it's on the internet or in the manual it must be true .....lolol
Just don't tell anyone it's well maintained. Doctor says use Vaseline and you use Wesson Corn Oil. Love this forum. Better than Comedy Central.
0 W oils are good for close to -40*F
My go to for the last few years has been Valvoline Extended Protection in my Hemi. Before was Pennzoil Platinum and is still one of my favorites.

on the two that i service regularly one gets Valvoline Extended Protection High Mileage 5w30 and the other (at request from the owner) gets royal purple 5w30.

Good Plan for the Cheesehead State.
I love the ep/hm ....running that now with 1 qt of restore and protect 5w30 of course
And what the heck do you think is the reason that choice would be bad? Lol. Your comparison is not even close to the same thing.
No differences that I can tell. This engine has always run smooth and get's 5000 mile OCIs, so I expect the innards to be fairly clean. It also has never used any oil between oil changes. . . I don't expect that to change. The real test on the Valvoline Restore and Protect will be in the wife's GDI Hyundai Santa Fe. I have some oil in my stash to use before that happens. . . probably next year sometime.
For those running a 5.7 Hemi, does your choice of 0W-40 influence your OCI interval (say, over a 0W-20 or 0W-30 oil?
I understand that the better way to assess the OCI is laboratory testing of the used oil but what, in particular, is the thought process to increase the oil grade?
Extended OCIs? Hemi tick camshaft wear prevention? Shear strength of the oil itself?
Educating replies/ links are requested. Thank you.
I am thinking of switching my 2022 Ram 1500 5.7 Hemi from HPL Preminum Plus PCMO to HPL Supercar 0W-40 for purposes of “best” cam lobe wear protection.

Oil won't prevent any catastrophic failure. Your 2022 should be outside of the years where the cam-lifter issue was prevalent.
I use Mobil 1 5w20, very quiet engine no lifter noise, and good oil analysis results.

This. If you've got some of the metallurgically compromised lifters, no oil is going to prevent their eventual failure, but 2022 should be outside that window, using the updated German lifters.
