I'm looking for some thoughts and opinions on the 6.4 Hemi oil spec I'm reading about. I'm new to Hemi engines, but always thought as long as I used an API certified oil with the right SAE viscosity, I was good to go no matter the engine. I have a Power Wagon on order so I don't have the manual in hand, but I've read parts of the download when checking for oil capacity and so forth. It is stated in the maintenance section: "We recommend using Mopar® API Certified SAE 0W-40 Full Synthetic Engine Oil which meets the requirements of the manufacturer Material Standard MS-A0921. Equivalent full synthetic SAE 0W-40 engine oil can be used but must have the API Donut trademark". After researching this material standard I found out the previous two year models fell under the MS-12633 specification. I'm not into oil chemistry and not familiar with these standards, but after more searching it appears that Pennzoil Ultra Platinum 0w-40 is the only oil meeting the MS-A0921 standard? I think that Valvoline, Schaeffer's, and maybe Amsoil began to include the MS-12633 spec to their formula meeting Chrysler's requirement, but then it changed to MS-A0921 so they are no longer are "approved" with the new spec? Not sure.
Now I realize this is only a recommendation, but I read about the unfortunate few having a severe engine "tick" with subsequent engine damage. In at least one case the dealer's service department asked what oil was being used and requested receipts. It was also said the engine oil was lab tested to check for the material standard. At first this seemed a little far fetched, but then I recalled one of my dealer service repairs and thought yeah this could happen.
So why not use PUP 0w-40, keep a record, and not worry about it? I have no problem paying a few extra dollars for the Pennzoil product, but it's not the most convenient oil to find in my area. Also, the last oil purchase I made on Amazon came with a leaking 5 quart jug. I've used the Castrol brand, easily found at Walmart, over the years and never had an issue. One truck I own has almost 200k miles and still going without any problems, so I'm considering going with that.
I hate to be negative, but it sounds like they are pushing people toward Pennzoil because of their partnership, or they're trying to formulate a special oil to reduce the tick instead of re-engineering the engine to reduce the tick. I don't think that the 6.4 Hemi is a particularly unreliable engine, but I do have a considerable amount of bad luck. I'm trying to identify a potential problem before I create one. Not to mention with supply chain issues, and this rapidly decaying economy, I'd like to keep enough oil stocked up for at least a few oil changes.
I searched the forum and found this older thread Mobil 1 or Castrol 0W40 for 6.4? that touched on the subject, but I was wondering if anyone here has looked into it or could point me to some more information. Also, do you have any experiences with the Hemi tick as it relates to oil brand? Any experiences at the dealer service department involving engine oil? Where do you buy Pennzoil online? Do you know of another brand with the MS-A0921 spec?
