Synthetic Oil

[U&A]

My 6.4 did it 2 times yesterday. I told the dealer last night just to have it on record and am taking it in for another oil change Saturday and will make sure they know it is happening. now every time i start the truck I stand at the door with it open and hold the phone over the hood, recording video, and then start it so if it happens I can prove it with the video and vin number in the video.

So I figured I would jump in on this. These two pictures are of the oil from the manufacture. First shot is at 70 MPH, and the second shot is sitting at a stop light.

Not sure if this helps, but I guess it could give us a baseline of what it comes with from the factory? I have almost 2700 miles on the truck now.

EDIT: Oh and the oil temp has never got above 212*.

Road: smooth asphalt hiway, flat, no load

2. OAT: 90F
Ground speed: 55 mph
Engine speed: 1600 rpm
Oil temp: 228F
Oil pressure: 52 psig
Road: smooth asphalt hiway, 6% uphill constant grade for 7 miles, no load

3. OAT: 99F
Idle: 700 rpm
Oil temp: 212F
Oil pressure: 43 psig
Ground speed: na

4. OAT: 104 F
Ground speed: 70 mph
Engine speed: 1600 rpm
Oil temp: 217F
Oil pressure: 52 psig
Road: smooth flat hiway, 500 lb payload
Note: 5w20 QSUD all measurements

LOL , I trust you sir

Can you provide a link to your trucks evic for us....... That would be great

@ raven3 , Sir your #1 cenario is almost identical to my current fill with 3ea 0W -40 + 4ea 5W -30.

I've read the Redline is thin for its weight though .

I'm starting to think there's two different oil pumps going into these engines. It seems most of us are either approx 44psi at idle or approx 33psi at idle no matter what viscosity oil is used. I find it hard to believe that's just differences in bearing tolerances...

 

[R.L.K.]

My truck on the factory fill and the free dealer bulk oils was approximately 28 psig at idle .

Oh ok never mind then. It's weird thats what mine was on any 5w20 I ran with the exception of RL 5w20 which was around 31. Now with 5w30 it's around 33. But cruising at 60 it's exactly the same as yours and everyone else's, 53-56.

I'm not really concerned it's just interesting to me that we all have the same engine thats supposed to be built to the same tolerances and yet there's this much variation in oil pressure...

 

[raven3]

All oil pumps have an over pressure spring loaded relief valve.
Maybe the relief valve could get stuck open affecting idle back pressure but not running back pressure measured upstream of the filter

Does anyone know the product code for a royal purple oil filter for a 2014 ram 1500 hemi 5.7?

Product code ?

Here's the P/N RP10-48

Hope this helps !

Redline is much thicker compared to other oils in the same weight.

at 40c RL 5-30 is 71, at 100c its 11.9 ,,now compare that to Pennzoil plat
at 40 c is 56.9 and at 100c only 10.3 . Quaker state UD is thinner than that at 40c 55.3 and 100c at 10.3 I could go on but of all my research redline is the thickest of any brand I checked with only Castrol edge black bottle being on par with it at 40c 12 and 100c 70 the RL 0-40 is even much thicker than the 5-30

I've seen the #s here and elsewhere, but my pressures are within a couple psi Cold start HIGH idle or @ 200+° idle or driving 55-65 mph , whether I'm running PYB 20wt , 7ea RL 5W -30 or what I'm running now 3ea RL 0W -40 with 4ea RL 5W -30?

Speaking only on the eyeball and shake and feel factor Redline 40 wt oil feels and looks the same to me as pyb 20wt oil ? Trust me I was verry suprized when I seen it myself .
I had convinced myself to go 2ea 40wt & 5ea 30 wt RL ( mostly based on the #s you and others had posted in the past ) , Untill I seen and felt by shaking the 40wt how thin it looked and felt , ultimately I went 3ea &4ea for my latest fill .

As to oil pressures I think its all in the oil pressure sensor being electronic they can be off or could be even a different part on older or newer trucks. I did replace my royal purple 10-48 filter reason being at start up with the amsoil 5-20 and previous PP 5-30 I would get a very slight faint valve train click on start up not a problem it just was annoying and I had 3 fast click start ups so switched to the wix-xp and I can tell you the noise is gone, fast quite starts every time now and I have 1-2 lbs more oil pressure readings than with the RP filter , the rp may filter better but it doesn't flow as good and these hemis need flow to keep oil moving imo so I'm done with RP

 

[R.L.K.]

What type & p/n filter are you running now Sir , instead of the RP ?

 

[RodRam]

All oil pumps have an over pressure spring loaded relief valve.
Maybe the relief valve could get stuck open affecting idle back pressure but not running back pressure measured upstream of the filter[/QUO


Oil filters also have a over pressure by pass valve if you run too thick a oil that it cant push it thru the filter at a safe psi rate it simply bypasses the filter element same as it does if a filter is full of contaminates and cant flow the required psi it bypasses, this could be happing and it would still read whatever psi the flow rate was. This is why I suggested to guys who run the thicker mixtures to check the SRT oil filters that have a stronger bypass spring to run he 0-40 oils

These are my normal stats for my morning drive to work .
I'm using Redline oil 7qt fill consisting of 3ea 0W -40 & 4ea 5W -30 oil. With a Royal Purple 10-48 filter .

This photo was in route to work this morning .

View attachment 72237

This was at idle at work with oil temps up to full operating norms for the conditions at hand .

View attachment 72236

And for anyone wandering if a higher wt oil drastically effects mpg ? Well I can't tell , so I'd say maybe just a tiny bit ?



For those who believes in the oil weight sliding scale my cocktail of oil would be 2.8W-31.4 RL.

My oil temp seems to heat up a bit quicker than my previous 30 weight and the free bulk oil from the dealer .

My oil pressures are very consistent with the PYB 20 weight oil with a paper pureoilater filter I ran in the past .

In closing , for those just tuning in at this point in this syn oil thread .
I've ran a 30 + weight oil for a smigg over 10k miles now and have Zero MDS problems and my 5.7L Hemi has no " hemi tick " ( never has had ) no abnormalities at all and runs smooth and quiet at all operating ranges .

Hope this helps .

I think RLK's gauges are messed up, how can you get over 26mpg with a 5.7 you must have a super high geared rearend??

 

[R.L.K.]

LOL that was a short trip

Don't let him fool you, he drives like a Granny!
