Same here, brother. Amsoil also came in the #1 spot in ELEVEN major oil filter tests in terms of micron size particle filtering, durability & construction. I only use Amsoil products for my car's lubrication system, because it constitutes a much more important amount of protection from wear than the difference between 0w40 and 5w40, which is non-existent unless you're driving in -20° weather.
Pennzoil is recommended by Ferrari for their US cars. Fiat owns Ferrari. Fiat also owns or owns a good chunk of Chrysler. Pennzoil wins... Manufacturer aside, I'm still at a loss on the whole 5W vice 0W grade debate...BTW, my oil cap alreadys states 0W-40. But my dealer used 5W-40 for the first oil change :dunno:
IMO, it's all "marketing" and corporate "business".
As long as the oil meets the mfg's spec and is the recommended weight, I'll use whatever brand is on sale, or whatever I'm in the mood to buy and try.
I've never had an oil related issue with any engine in over 40 years of driving my cars hard.
Right now I'm using Castrol Syntech in my R/TC. For the winter, when it gets more down time, I'll go back to a non synthetic.
For some reason, many of my cars just seem to "use" less Castrol than other brands. Probably due to the additive package in their oil, but I just prefer Castrol.
That being said, I have no problems with Penz or Mobile One. I don't like Quaker State............................I don't like "green" LOL
Manufacturers contract with suppliers that will meet their spec and the price the maker is willing to spend.
Since every SRT vehicle comes down the line with 7 qts. of (fill in the blank) oil, that's a lot of product purchased during the year (for all SRT: Chrysler, Dodge, Jeep and SRT-only models).
Its similar with tires - sometimes a different supplier will have a more favorable bid and if it meets the mfgr's criteria, they use it.
The engine oil specification for the 6.4L is full synthetic API grade SM or SM/CF (or higher). API grades are now at SN (higher then SM). Mobile 1 satisfies this specification every bit as well as Pennzoil.
Here is some actual information on SN as comported to SM: Linky.
I just ran into this earlier this morning. I took my car into the dealer for an oil change and checkup. The local dealer lets you bring your own oil in, so I told the guy I bought my own oil.
"What kind?"
"Mobile-1 Synth"
"Why?" (the accompanied look on his face made me think I had just told him to put River Water and used Coffee Grounds into the engine)
He then proceeded to give me a five minute lecture on how Pennzoil Synth was better because blah blah blah and Mobile-1 was "ok" (which the look on his face then changed to disappointment...like I was a toddler who just flushed dad's new cell phone).
Look Pal....this car has 140,000 miles on it, I've been running mostly Mobile-1 in it for almost 9 years, and it runs like a top.
I have nothing against Pennzoil (that was what I was originally going to buy when I was at the store, but they were out of Pennzoil Synthetic 5W20...so I bought Mobile-1)...but this "Hard Sell" crap is just taking things a bit too far.
Ill use whatever they want. Now days if there is an engine issue they want receipts and documents showing service. They will void the warranty on any technicality. If u change the oil regularly there will be no issue with whatever u use. I use the pennzoil they suggested but I also get a nice discount too so that puts it about $7 a quart. Not to shabby
If you change your oil often and use a good name brand synthetic oil you won't have a problem.i have the Dodge dealer use there best synthetic oil and I change my oil every 3 to 5 thousand miles.
The clincher for me is the $$$. I can get Mobil1 at wallyworld for essentially $5 a qt. The Penn is $7 almost $8 at wallyworld. And the damn auto parts stores are $10 for each.
Doesnt the new SRT Penzoil 0w-40 have more moly in it, like 250 PPM vs 100 for Mobil 1 0w-40 and that is claimed bt SRT engineers to be a benefit for the 6.4 for the cam phasing?
Not sure in the real world it would matter that much.
Not sure how much benefit the Moly is, but I believe that Shell specifically had to bring 0W40 Pennzoil Ultra to the market because of a cam phasing problem with the SRT engine. There was a problem using 5W40.
So I think the critical aspect for the cam phasing is more to do with the oil weight.
