As posted above and many other places all these 5.7s do seem to operate and respond a bit different to mods and oil types .
I do think the oil filter has as much to do with startup tick or noises as the oil type you choose to use .
Seems to me after a significant amount of reading here on the forum and abroad , the same 3 things come up over and over that the experts and some that people consider experts through personal experiences / experiments.
What I'm posting below is simply from my reading here and abroad . I'm posting up what has been determined by many to be either the most favorable option or an acceptable option though discussion, experience, research and experiments .
#1 oil filter type .
A quality anti drain back valve "ADBV" with silicone sealing . FULL synthetic filter media material .
This is why I ultimately went with the Royal Purple 10-48 filter.
#2 Oil type .
Good or high Moly , zinc and a robust claening/ additive package . Ester base also seemed to be very sought after .
These reasons above is why I ultimately went with Redline oil.
#3 oil specs / oil wt.
This one really seems to ruffle a lot of feathers ... I could write a book on all the discussions I've read here , other forums , lab test results discussions and through Google searches on the 5.7L Hemi MDS and what Chrysler Corp has to say as well .
I'm not gonna elaborate much on all of that ..
The above info is why I ultimately went with a 30wt. Oil . Spacifically Redline 5W -30 oil
I've never had the "hemi tick " @ startup or @ operating temp ; however, I did always think my 5.7 was a loud running engine .
I can tell you this with absolute certin knowledge of my personal experience with my 2014Ram 4X4 QC 5.7L with a 6 speed .
When I installed the RP 10-48 Filter with 7 qts of Redline 5W -30 wt oil my 5.7L has never ran smoother or more quiet in the previous aprox 26k !
In my garage with doors shut I can here my radiator fan blowing . Never heard my fan before .
I've pulled up beside other 1500 Rams with the 5.7L at a stoplight with my window down and I hear their hemi over mine .
I've got a little over 3k on this oil & filter and I've had Zero issues no drop in mpgs , no codes and MDS works like a champ . I'm **** as hell and I watch Temps , pressures and mpgs like a hawk . I believe I have a good set up for my 5.7L.
I checked my oil a couple days ago while gassing up and on the dip stick it looked like the day I put it in .
As alluded to above on Burla's post , I'll be experimenting with 2 qts of Redline 0W -40 added to 5qts of Redline 5W -30 on my next oci , this mixture will give me aprox a 3.5W-33 weight oil .
The advantage I'm hoping to get by adding the 2 qts of 0w -40 is a more robust additive package , a slight increase in viscosity and a slight increase in film strength.
Sorry for the long post , remember these are my opinions and experience / experiment. I won't tell anyone what they should or must use , just putting this out there for the read and to help others make their own informed decision.
Hope this helps !
