Interesting statement on 5W-30 oil being used in the 6.4 instead of 0W-40

[Hootbro]

Yeah, you guy are going to like this. Below is a video with the Ram director of marketing and Ram director of Engineering taking questions on the Hemi truck engine family.

At the 13:42 mark, there is a question poised to them on why Ram 6.4L requires 0W-40? They go into detail that the Ram 6.4L truck engine DOES NOT require 0W-40 and can use 5W-30 and even a non-sythetic 5W-30 at that. Also, all their durability testing was done with 5W-30.

I do not advocate deviating from the manual but gives food for thought that the call out for 0w-40 was more to align with the SRT 6.4 than any need for the RAM truck 6.4.

This should make some guys here happy because I know that 0-W40 grade synthetic is expensive.

Regardless, it is still just a video and I would not recommend deviating from anything that is not called out in the owners manual while in warranty. Seems FCA looks for anything to deny a warranty and pulling out receipts for 5W-30 oil changes instead of the correct MS-12633 spec'd 0W-40 can cause complications.

"...yes I realize you are denying my warranty claim because I used 5W-30, and yes I see what the manual says.....but here is a YouTube video of your boss's boss's boss's boss saying it was OK so suck on that OK?"

Or stick to 0W-40 for now......lol

Deviate from the 0w40 and get a CEL. Not worth it to me since that disables command start and MDS and fiddles with the timing a bit. Good to know that if you are in a bind though, you can use it.

Is that for sure it will throw a CEL? I had my last oil change done at the dealer ($100.00+ freaking robbery). When I picked it up the slip said 5W20 on it, I question the cockroach oh I meant service writer about it and he told me it was a typo and lined it out? Not sure what to believe on that one (saving that slip though)

That was 3500 miles ago and no CEL yet.

Yup. If the viscosity is not within the specs in the system (whatever the hell that is) it will throw a check engine light and will produce a code. I can't remember the code unfortunately but the tech showed me the print out and it said "incorrect engine oil viscosity detected" or something along those lines. When I bought my truck it had 5w20 in it rather than 0w40. As soon as the oil was changed and the start cycle was done twice, the CEL went out. Pretty sure yours was legitimately a typo otherwise you would have seen the CEL by now.

Holy crap these trucks are advanced.... Thank god my wife doesn't have the same ability or she'd be able the pull the "stopped at the ***** bar on the way home code"

The CEL code for incorrect oil is P1521.

Wouldn't WD-40 work the same as 0w40?

Um. No?

I don't know how I would spray all that in there without making a mess either.

My question was rhetorical...

I was playing on it being a typo. My bad.

I remember having a heated discussion with the tech lady at my first Oil change on my 2014 6.4 Ram, I had to open the hood and show her the writing and that it was synthetic. Like SouthTexan says the price of each oil change is wow but the 1500 5.7 oil change light came on at 5000Kms every-time, where as my 6.4 goes more then 10000Kms before oil changes so still works out cheaper. So far I've changed the oil on my 6.4 at or before 35% each time... wonder how far the truck will go if wait till something like 5%?

my second oil change.. I sent the monkey at pep boys to grab me a box of 0-40 ultra penz... it wasn't sealed and I told him I only needed 7.. checked the first two and called it good." Mind u I was 600 miles from home".. put the oil in the back of the truck. 4 days later at about 7 o'clock when it was just getting dark started changing my oil.. Not really paying attention got done pouring the last one in.. and noticed the ******* bottle said 5w-30.. looked identical to my 0-40. pulled he rest of the bottles and it was 4/5-30 to 3/0-40.. .. well **** me. Called orielys locally and waited a week for it to show. It was 100* days at the time so I just made sure I let it warm up. Put 100 miles on it then changed it out. It never through a cell, I did notice at start I did seem to have more oil pressure... But I am sure it didn't hurt anything. I love letting some kid who makes 8$ a hour tell me/ give me the goods for my 40k truck.

No typos here...

 

[reb0957]

I always see that our only option is Pennzoil Ultra but I just looked it up and Redline and Amsoil see they meet MS-12633. I could have sworn my owners manual said Pennzoil Ultra 0w-40 but it doesn't. Just lists the spec.

Anyone using redline or Amsoil?

This is off topic, but does anyone why they call it WD-40 without Googling it?

Water Displacer, version 40. Anti-Corrosive surface treatment for warheads IIRC.
