When i asked the mopar master tech why they were not running 5w40 oil such as rotella t6 in the hemis, he said they would probably set an incorrect viscosity code. But that seems to be nonsense and i suspect it would greatly reduce the number of motor changes he does.
That would be the P1521 code. It can be set for other reasons as well. It's my understanding that the ecm monitors the signal from the oil pressure sender and compares it to a programmed value in the ecm. It can tell if the oil is the correct viscosity, probably by the oil pressure signal the sender is providing. I've never actually had that code nor did I ever work on a customer vehicle with that code in my years at the Chrysler dealer or in my own business.
I had a comment from a friend lately talking about someone he knows who has a Ram as were were talking about what he thought of his own ford f150 with the 5.0 engine, as he made the comment that this person with the Ram is on his third engine with only 85000 miles on the truck. I have no idea if that was the same engine being rebuild or reman engines etc so the quality of what went back into the truck was the unknown to me or what happened to cause the first two engine failures. I have seen on youtube as per mechanics that have zeroed in on blaming lack of oil flow from the stock pump and using a pump used for certain Chrysler applications that has more flow. Also have heard just as you are doing as per using a higher viscosity oil or trying different oil brands and finding some cause the noise and some brands much better so the claim goes. Sad but true, it seems all the big three have created engines that have issues with rockers, lifters and therefore wiping out cams. Its very disheartening to look at the price of new vehicles and how unreliable far too many of the engines are and we the consumer suffer financially for the crap they create. By the way as per the T6 oil, I was looking up the API ratings and of course as its geared towards diesel engines it has a CK-4 rating and as for the gasoline rating, API SN. Does your Hemi ask for an SN rated oil or the current SP rating ?
Great comment! What I looked for in the Rotella was that it is MS-6395 compliant, and it is, which the Hemi calls for. I have no worries using this oil in my engine and so far it's been excellent. They say you can go 10,000 miles between changes but I tend to change mine every 5000.
@@SteeveeDan I am not familiar with that Chrysler oil specific designation and in reading just now its basically become a somewhat obsolete rating in that most oils meet/exceed it years back already and formulations have changed since then to meet current standards. As to how often to change oil, so much depends on climate, how long or short the trips are and if pulling loads vs driving empty etc. Since some of that "oil monitor" so called technology has come out and the environment nazis pushing for fewer oil changes, I am pretty sure that has been the early demise of a lot of engines out there as per owners who drove way too far with short trip driving and sludged up their engine because the "oil monitor" told them they could. I'm with you on that, 5000 miles at the most and in more severe conditions cutting back to 3000 mile oil changes, most engines will thank a person for changing it more often rather than pushing the limits. And if a person doesn't mind doing your own oil changes, you KNOW what oil actually went into the engine as well as choosing the filter of your choice, and that the filter won't fall off or the drain plug fall out ! ( and owning a grease gun with good quality grease for those vehicles that do have suspension/ujoint etc grease zerks )
@@charlesb4267 I tow very infrequently these days and when I change the oil at around 5000 miles in the Hemi, it still looks much better than both of my previous 5.9 Cummins and my Ecodiesel I had that were changed at around 3000 - 4000 miles with Rotella. I get it that the soot from the diesel fuel plays a part in the oil appearance, but like I said, several Rotella oil changes in the Hemi, zero valvetrain noises and pretty decent mpg for what it is, I really couldn't be happier! I agree, the dash mounted oil minder is a really bad idea. The owner needs to monitor the type of use that the engine experiences and change the oil/filter in time/miles based on driving and usage accordingly.
@@SteeveeDan Definitely the soot plays a big part in why a diesels engine oil becomes black much sooner on within a proper oil change period but how its being used and condition of the injectors, the technology of the injection system ( higher pressures tend to equal a cleaner burn ). Unfortunately when they decided to put EGR on diesel engines, that was a giant step backwards with forcing carbon particles past the rings into the oil ( it would be like a human eating your own ... well you get the idea ! ). I have one tractor on the farm that has EGR on it and within one days use from a fresh oil change the oil is black as black can be, its just maddening and I change the oil on it well before the recommended drain interval to do what I can to help it survive. Just curious, what area do you live to get an idea of the humidity and temperatures year around that you have. By the way if I had not mentioned I live in more the northern part of Alberta which means cold winters and block heaters on engines are a must ( and the right viscosity oil for those conditions )
I would use a euro spec oil M1 0w30-ESP is a thick 30w, Royal purple 5w30 and several 0w40, also qusker state 5w40 is a great euro spec oil. Cold weather will matter. Also dont worry abour being half a quart low, I actually remove a quart jn cold weather. I do agree that 20 weight is too thin, because oil breaks down and breaks down fast because of alcohol in gasoline. Remember that 5w40 rotella is thicker than a euro spec 5w40, so you still have room. But I agree its better to be too thick than too thin.

18.1 in a Rebel!? Wow! I'm lucky to get 15 (or slightly less). Is the oil the only thing you do differently? I would love to get 18 in my 2024. I'm not sure I want to go with the T6 though I have been considering a 0W-30 instead of the 0W-20 that is called for. I did that with my Ecodiesel, until it blew up (crap engine design).

@@Michael-B41 not sure if older was better. I imagine the mds is problematic, I've got a 2016, I run a little heavier on the oil. I run full synthetic pennzoil platinum running 5w30 in winter and 10w30 in summer with a quart of Lucas. I don't want to jinx it.

Believe it or not, coming home from work last Tues night it was chilly and I was about 26 miles into my drive home pulling a hill and thought "lets check my oil pressure". Flipped through the settings and saw that at about 50 mph I had 51 psi. Other than that, I really never think to check it.
@SteeveeDan thank you what about at idling I get the same while driving I always keep an eye on my oil pressure it's like the heart from the car great video by the way thank you
Strangely enough, I started the truck this AM, 24 degrees and after about 5 minutes of idling, I had 53 psi at idle. I did take a pic but guess there's no way to add it to this post.
@@SteeveeDanis that good or bad? What should it be doing during various circumstances? I have a wife and two teens so four cars to maintain so always trying to learn and save a buck diy
@ That's a good idle pressure. Compared to other vehicles I've owned that had 20 psi or less at an idle, this is good. Cold oil pressure will typically be higher than a fully warmed up engine. Oil pressure drops when the oil gets to operating temperature due to it thinning out somewhat. I'd be happy with 45 or 50 psi cold and 30 to 40 psi hot at an idle. Psi also tends to drop as the oil gets old because it breaks down over time.
I use 20w50 amsoil fully synthetic

Why aren't you sticking with an oem filter?
Truth be told, it's my understanding that Mopar oil filters are made by Wix and/or Purolator. If I have the opportunity, I prefer Fram.
I would use a euro spec oil M1 0w30-ESP is a thick 30w, Royal purple 5w30 and several 0w40, also qusker state 5w40 is a great euro spec oil. Cold weather will matter.
