If you read the mileage on evic and test mileage by hand, you will see two vastly different values, so how can you trust anything that comes through evic. I barely trust mph, lol. We all know we should idle as less as possible, but sometimes it is necessary, so just live with it. Plus city driving comes with a lot of idle, are we supposed to switch to neutral and rev engine at every stop? Put a good oil with high additives to protect metal more at idle and dont worry about things we cant control, bump up idle if you have the desire to.

-54 oil is a Popsicle, by the language my guess is -54c, which is -65f. Seams like many different sub zero temps posted, but I'm not sure what we can do with this as I don't speak that brand of jibberish.
Interesting video for us oil nerds. Youl likely enjoy it more if you can speak russian but the visual is still interesting. Its mobil 1 fs 0w40 pour point testing from the russian oil club. Mobil lists it as -60c and they deep freeze it to -70c and see at which temp it flows. Obviously even if it flows under its own weight at -66c like in the video it wont do much protecting inside an engine as its thicker than caramel. Still an interesting video none the less for us oil nerds.

Just an interesting visual is all was intended. Ill delete it
That's been my experience with Mobil 1 EP 5W-20 vs. Mobil 1 FS 0W-40. RedLine 5W-30 may have added another PSI or two at hot idle as it's got a thicker base and less VI than M1 FS 0W-40. Ergo, none of the lube manufacturers publish accurate numbers, that's why they call them "typical properties" that can vary from batch to batch.
That's a pretty ignorant statement to make as the gentleman in the video speaks Russian, and he is searching for the pour point of Mobil 1 FS 0W-40.

No idea. To me the EVIC is just another black box created by out of control coder dweebs.

The oil psi on the evic does match what the pcm sees for oil pressure. I've seen this with a scan tool. Since VVT and MDS require precise oil pressure, I'm going to say what's on the evic is pretty accurate....
The EVIC gets its info from the PCM.
You were 100% correct. Sorry about that. The system is analog, driven by a... spring. It reminds me of a Maxitrol gas pressure regulator, lol, as they adjust gas pressure, precisely, I might add, with a spring. Though said spring can be adjusted if you have the right tools.
You are correct. It's a real-time reading, with a minute delay induced by the analog to digital conversion. However, it's barely noticeable.

Might have time to check with HPtuners beside the evic tonight.......good to see some intellect on this site.....LoL
This site has over 120K members. I'm pretty sure none of them feel, even a little bit, insulted by your statement.

The whole point of this is to not idle unnecessarily, or out of habit. i.e. - don't leave it idle while you're out looking at something, or filling up with gas (illegal anyway), or whatever.
I just mentioned the EVIC out of curiosity my proximate idle % - not some precision data number. I haven't trusted software since they started using it in controllers at work. I saw how out of control those people were.

I'm very interested in reading more about your experience regarding the above statement. Thank you.

Yep, I agree on avoiding idling as much as possible from what I've learned here in the forum from you folks.
I've owned the newer HEMI powered trucks from 2009 to 2017, five in all and didn't read much about the lifter/cam failure and exhaust manifold bolts breaking off, etc. until I started reading about these things here in the forum.
I'm fortunate I've not had or have these issues with any of them and hope that that by the oci's I've done at ~ 3000 miles was what might have been and is a good thing when I was using Pennzoil Platinum 5W-20-30/ MOPAR/PUROLATOR BOSS oil filters?
I've made the change over the last part of August to Red Line 5w-30 and still use the PB oil filter with extremely impressive results.
My current HEMI had the occasional cold morning dry start ups on the PP oil/MOPAR oil filter and noisey upper valve train ... I'm at ~1600k now on Red Line and all is good.
It looks to be that my oci's will be once a year now as for this HEMI RAM sits under my carport alot since my retirement.
I hope this truck will last me for awhile ...

Yep I retired several years ago and don't drive much anymore either. How many miles were on your other 5 Hemis?

The mileage on my previous HEMI's were ~ 25-30,000k as I traded them off for a newer one for some type of new gagit or different color ... heck, I traded off one for another in just a little over a month's time because I decided I didn't care for the color ...
The current HEMI is a 2017 Express RCSB that has afew more options on it than the last four fourth gens. It's apparent that I'll be have to replace the tires on this one.

anyone grease their wheel bearings through abs sensor? Seams like some guys on eco diesel forum do so.

I haven't.
I had thought that that the wheel and rotors (on the front) were one combined part and when the rotors we're worn down to replace that whole thing because the bearings are sealed? Idk ... I'll read up on it.

Ive thought about but just havnt attempted it yet. Seems like a good idea to me
The best way to disable your MDS altogether and induce cam phaser delays is to run thicker oil, it seems. As stupid as that might be, it also seems to me that the PCM is married to 0/5W-20. So unless you get a custom tune, the 5.7 HEMI doesn't work correctly with higher viscosity oil.
You don't have to believe me. Just get any decent OBDII Bluetooth scanner and a JSCan ($23.99 per VIN license) and monitor your MDS and cam phaser.
Of course, people who get custom tunes with upgraded HEMIs probably no longer desire MDS. Cam phaser operation is another issue, though.
So much for "just run RedLine 5W-30, it'll be just fine." Or Mobil 1 FS 0W-40, for that matter. It won't.

Wait, the bearings aren't "sealed for life"? :-D
