Greetings all,

I bought my 2022 Ram 1500 4x4 5.7 new. I have talked about the lubrication of the 5.7 at LENGTH with my local dealership as well as anyone else who claims knowledge of the Hemi 5.7.

I use Wix filters, and the Penns Ultra Platinum Synthetic oil. I recently had a conversation with an actual chemist who does oil analysis and works for a company that makes cam shafts. My query for him was, is the OW-20 good enough for use in AZ. We typically get triple digit summers and that oil seemed off to me and I asked what would be best as I have read many people switch to 5W-30 which makes sense. He advised moving to OW-40 and that would may also help with the dreaded tic.

It is claimed that moving to the OW oils is due to closer tolerances being used now to both save fuel and for emissions etc. I don't know that is true but manufacturers are pushing for economy and smog reasons. Honestly I could care less about either issue, I just want to maintain my engine as best I can. So the correct/best suited lubricants and a reasonable change interval makes sense. I do not abide the whole change the oil when and if the light comes on mentality, and the new trend of NO dipstick is beyond reason for me anyway.

I spoke to a performance engine builder who builds and races Mopar's and his advice was to replace the oil pump with a higher flow unit as the system was not getting enough flow during idle periods. That causes wear, that in turn leads to the tic. I also heard that the oil pump from the Challenger I believe is a better unit and could/would solve the issue.

I have watched HOURS of oil tests and comparisons, as well as for oil filters and it is easy to get off into the weeds. There is apparently no simple answer to these issues. I get oil needs to be able to flow in various environments/temps, and that the oil pump as well as the oil filter do affect that ability to lubricate the engine.

I don't know that this will help find the solution, I just wanted to share what I have found to date, in hope that someone else may have found more information or something that makes good sense.
 
I would only listen to manufactures on oil if there is an engine failure and the shop does a oil analysis and finds out its not the recommended type/viscosity you may be on the hook for the engine
 
First thing I would do is check the exhaust manifolds to make sure the ticking is t coming from there.

As you have found there are many different OPINIONS out there as to what is best, and it all depends on who you talk to.

The 0W oils are designed for better flow when cold and have nothing to do with engine tolerances. The second number is the "weight" of the oil and that's where tolerances come into play.

I get my oil from a guy who custom blends oil as a job who is a certified tribologist and has the degree to back it up.l, and is also a Mopar guy and owns several modern Hemi vehicles. He sends me 7.5w-23 oil.

This subject has been beat to death ever since there have been vehicles that use engine oil. You will never find a general consensus for what is the "best". Use what you are comfortable with. You will rarely ever change anyone else's opinion.

This is false. 0W-20 oil is 0 weight oil that has had modifiers added to it to make it perform like 20 weight oil at 180 degrees.

Race engines have nothing in common with daily drivers. They use the thinnest weight oil possible to gain the tinniest of margins at extreme cost to longevity.

Synthetic motor oil is made from the same crude oil as non-synthetic. The difference is that hydrogen gas is added during the cracking process to fully saturate the hydrocarbon chain.

0W-40 oil has less oil and more modifiers than 0W-20 oil. You decide.
 
the number before the W is the "winter" weight so this will be the viscosity when cold. the number to the right is the viscosity at operating temp
 
Like I said you can never go wrong by putting in what the manufacturer recommends but can get screwed for doing otherwise

We have a certified tribologist here I see

As you mentioned, many opinions on this topic. I would love to hear from any 5th gen HEMI owners that have used the 0-20 oil its whole life and have well over 100k miles on the clock. What would they say? Any engine problems?

I have 5,300 miles on mine and plan on changing oil for the first time at 7,500. Anyone changing oil sooner than that with full synthetic is just a waste of money and time in my opinion.

I came from an F150 2.7 eco boost. Ran synthetic and changed it every 7-10k miles. Also used the factory recommended viscosity. Using either Mobil-1 or Pennzoil Platinum. It had over 120k miles when I sold and zero engine or turbo issues.

Bottom line, I will ALWAYS use the viscosity the manufacturer suggests.

here is a thread dedicated to oil viscosity

JBV

Thread '0w 20 oil, to my surprise'

i decided to do my first oil change early, around 2000 miles and to put in Penzoil Ultra Platinum with a Napa gold filter. did some research here and elsewhere, checked the manual, bought the oil and brought it to my fav oil change place. he said that you got the wrong oil. i said pardon? impossible. i look at the filler cap and it says 0 20. i was shocked. he said this was the case more and more with newer trucks. so i called the service dept at the dealer and they confirmed, 0w 20. so thin!

despite the manual and everything else i've read, my 2022 Ram Big Horn 5.7 takes 0 20 oil...

I believe 0-20 started in the trucks in 2022 so unless someone drives a ton there may not be any with 100k, at least on this forum.

Thanks. I didn’t know they started 0w20 in 2022 since the truck was redesigned for model year 2019. Good to know. I’ll still follow OEM suggestions.
 
My 2019 5.7L 710 cap says to use 0W-20 oil. I gave it its first oil change at 800 miles, switching to 5W-30, and drove around the country for about 7000 miles, then changed the oil again and put in a remote filter kit. Always 5W-30 and every 3000 to 5000 miles. Frequent oil and filter change is a small price to pay for this excellent engine that was absolutely quiet until exhaust manifold bolt broke at about 85,000 miles.

I like that remote oil filter setup! I switched to 5w 30 at 6k im in AZ and we get triple digit temps and i am now towing 7k pounds with Toyhauler. Not gonna use that thin oil in the enviroment im putting this truck in .

Totally agree. Seen some high oil temps crossing the mountains. I don't know how thin 20W oil is at 237 degrees, but it can't be good for this engine.
