Engine oil addendum.
"The manufacturer recommends the use of a full synthetic SAE 0w-40 engine oil or equivalent"
2012 model year SRT 's equipped with the 6.4 liter Hemi engine
" the user guide and tip card for your vehicle VIN xxxxxxxxxxxxx incorrectly stated the use of SAE 5w-40 engine oil instead of the correct oil which is SAE 0w-40 full synthetic engine oil"
Interestingly, I went to my dealer's 'Customer Appreciation Dinner' last night, got a coupon for a Free Oil change and had the work done while I ate dinner. Sweet!
There was a bit of a faux pas, though; At first, they couldn't find the 0w-40 oil that they were supposed to have in stock...
They finally found it after 45 minutes of searching.
I got complimented for having one of the nicer Challengers that they have seen;
I think my switched Footwell LEDs impressed them the most.
I was told by my dealer than they switched to Pennzoil Synthetic for 2012 (I know, from Mobil1 to Pennzoil, really??) and then at the last second they switched back to Mobil1. No idea on viscosities, but 0w40 makes sense since that is what it used to be ("back in the day" of the LX SRT8s). I was told my Challenger (custom order) sat on the lot in Canada a week longer because they had to drain the oil and refill with Mobil1. Something about a bad batch of Pennzoil coming through during final inspections of the first 2012s, so they yanked them all and had to do the drain/flush/refill using Mobil1, hence the delays... *shrug* Who knows if it's true, I can't hardly believe anything my dealer says... but this one is beginning to sound like there is some truth to it... ???
i have a 2011. had the oil changed about a month ago at the dealer. they put in 0w-40. didnt think that much about it at the time. ive got a case of 5w-40 in the garage. still use it? probably
When I had my Viper Truck (2006), it required 0w-40 Mobil.
Mine is up for a change... so I will have to ask....
Seems odd, since Pennzoil is (maybe was now) the official oil for Ferrari and Maserati F1 Racing, and part of the contract what that ANY Fiat owned company had to use Penzoil products on their first fill.
My dealer has been putting in PZ 5W-40 Ultra Synthetic.
But even if they switched to Mobil I dont mind that either...
I wonder if these 392's blowing up was actually not a bunch of BS...........I havent seen any but have heard a rumor that the 392's were having piston problems. Chrysler was changing the oil to 0-40 for a "fix"........HMMMMM.
OK, my limited understanding about oil numbers was the numbers translatted to weather temps. the first number was for the low temp range and the second number was for high temp range.
like 10w30 = 10 is for climates where temps get down to 0 degrees and the 30 was summer temps get up to 85 degrees.
I used to run straight 50 weight on one of my race cars.
The 10W number is rated at -20C for viscosity, 5W is rated at -25C for viscosity and 0W is rated at -30C. The viscosities of 0W, 5W and 10W are nearly constant at these temperatures.
The higher number is different, the viscosities are all determined at a constant 100C and the lower the number, the lower the viscosity.
I don't plan on driving my 392 at -25C; 0W-anything is for fuel economy, nothing else, unless you are talking a cold oil engine like a drag engine.
yeah, its a rumor I heard. I also heard there was a shop in South Florida with several 392's getting engines replaced. Who knows. I still say its just a rumor.
Hope we get this figured out...I am quickly approaching my 1000mi first oil change and if I need to run 0W-40 that's fine...as long as Royal Purple makes it...
I haven't received any letter...but I have only owned about 3 weeks...my book also says 5W-40 Pennzoil synthetic but my last SRT I ran Mobil 1 0W-40 the whole time I owned it...
Picked up my car about a month ago and there was a card in the owners pack of papers calling for 0w-40. If I remember correctly the car was manufactured in November.
Well, going to have to find another dealer. The service advisor at grapevine dodge refused to put in mobile one, said dodge stopped using mobile one because it caused catastrophic engine failure :soapbox: obviously they are oblivious to what is reality
What a pack of B.S. Then if that was true, all the other car mfg's that factory fill with Mobil 1 would also be having engine failures as well.
Sounds like the Chrysler dealers where your at are as stupid as the ones around me. I love my car and the only reason I would sell it would be because of the lousy dealerships making my warranty almost useless!
I just got back from the dealer and they put Penzoil Ultra 0W-40 in my 2011 392. I showed the dealer my owners manual and oil cap which shows 5W-40. He showed me a service advisory from Chrysler that states to use 0W-40 on the 6.4L (no model year shown). Te 2012 392 on the showroom floor oil cap also shows 0W-40. I was thinking they switched to the thinner oil for the MDS available on the 2012 model. Since I have a 2011 manual trans, I have to now wonder what oil I need? Do you guys know if any tolerances were changed between the 2011 and 2012 392 engines because of the MDS? Am I OK with the 0W-40 for a mild to hot climate in CA?
Here is what I know about switching to 0 weight. Honda switched all of their cars to 0W-20 in 2011 model year. I am told the ONLY reason was emissions and carbon footprint. And a tiny bit of gas mileage efficiency.
So I am only assuming that Dodge is switching to help them meet some government requirement with regard to emissions. And they probably had to wait until they had a supplier in place that could fulfill the order until they made the complete switchover. There are some very hefty CAFE regulations looming for all the manufacturers.
My 2011 has 5W-40 on the oil fill cap. But when I had my oil changed yesterday the Dodge store told me that I should be using Mobil 1 0W-40 moving forward.
The oil cap on my 2011 392 says to use 5W-40 synthetic engine oil. If continuing to use the recommended oil type both on my fill cap and the owners manual caused engine failures, improper emissions operation or MDS malfunction, then you'd think they would issue a recall or something along those lines with a new fill cap and updated portion - or "revision" to the owners manual.
Otherwise, there's nothing legally Dodge could do if you had problems caused by the oil type that's recommended. Dodge would be responsible for any failures caused by the oil...maybe the 2012's are different from the 2011's...
I'm not saying that your dealer didn't say to use another type of oil, but my dealer/service rep didn't know that the door handle TSB applied to Challengers either. He showed me an older TSB that covered everything but the Challengers....I had to show him an updated one before they'd believe me....is there at least a TSB or anything official that anyone has found on this??
I think everyone knows engines won't fail due to switching from 5W to 0W oil. But my point was, if there's nothing official that comes from Dodge, they certainly couldn't void any warranty's based on not using the rumored "0W" oil....but I certainly appreciate your reply.
Agreed have not seen a failure do to that type of change....but if you dont and Chrysler finds out AND you have a problem it would give them grounds to deny a warranty....just saying someone with personal knowledge of their warranty handling history

And that would be a great point if I got a note in the mail, or I was enlightened as to the change somehow. I've seen nothing in my mail about it. So -if I were to change my own oil (which I do) - and I continue to use what is in my owner manual and printed on my oil cap...and Dodge did not notify me of any changes, I'm responsible??? I think not.
I called Chrysler yesterday and asked for clarification. They said that they had indeed switched the viscosity from 5W-40 to 0W-40 for all the 392 engines. They plan to mail owners a notice and 0W-40 stickers to place on the oil cap in July. I guess it takes a while to print them stickers...

According to MC88 it's officially 0W-40 for all 392s, according to him none of the 392s actually shipped with 5W-40. They drained them and refilled them with 0W-40 before they went out but didn't get all the caps changed out.
The 0W viscosity in a 0W-40 oil only means that it is the lowest low temperature viscosity currently defined by the industry standard SAE J-300 specification for motor oils. It's an arbitrary scale defined a number of years ago. It does not mean zero viscosity. Also, the wider the multi-grade, the more chance it will contribute to engine deposits. The low-temp cranking rating for 5W is -30 degrees (as in below zero) Fahrenheit. For 0W it's -35. I don't know about the rest of you guys, but I can't recall the outside temp in my neck of the woods dropping to under 30 below zero....recently:spineyes:
Funny you should bring that up, I was talking to MC88 a couple nights back and he was telling me about the testing procedures they put these cars through, and one one them was driving it through deep slushed snow in almost 0 degree weather (I'm assuming they add water to make the snow slushy) and then pulling it into a chilled enclosure that is -30 and leaving it there for 24 hours. (to simulate a driving through a blizzard and then parking the vehicle) After 24 hours they then go in and attempt to start the vehicles (all SRTs) if they start they pass, if not they figure out that they need 0W40 instead of 5W40 :icon_biggrin: (the 5W40 part is a joke, the testing procedure is for real)
