[QUOTE="jhenderson,
Kinda like John Deere HyGuard. A lot of oils claim to meet that spec as well as many other manufacturers specs all in the same jug. Ask a JD mechanic how many transmissions he’s repaired that had someone else’s fluid in them vs the ones who only run JD hydraulic fluid.

I am pretty sure John Deere's jug says the same thing as everyone else's jug. I use this in my John Deere's, Case/IH and customers tractors and don't look back.

Pretty sure don’t cut it. You’re installing oil that meets JDM J20 specs. Hygard meets RES 10060 specs.
 
Two things.
This Might actually be meaningful if the fluids in question were synthetic. The vast majority of OE specd fluids are conventional.
Second, I wouldn't be so quick to give credit where it isn't due. Companies like Mobil and Shell have done more to advance the oil industry as a whole than a boutique company like Amsoil ever has or will.
That's not meant to be condenscending, biased or emotional. It's just fact.


Please tell me who is it that were producing Synthetic oils in the early 70's for the automobile industry.

RAM/Cummins trucks diffs and engine are filled with synthetic oils. Isn't ATF+4 synthetic and AISIN fluid also?

Dino oils are simply not just Dino oil any longer.

Try Schaeffer's. Been around since wagon wheel grease was still a thing (no joke).
Supplied products for the US military for a World War and Desert Storm. Amsoil is far from the first to do it, but since we are talking large manufacturers Mobil has also been in the synthetics game for more than 40 years. Who do you suppose has bigger pockets of the two?

As to your 15k mile OCI, conventional oils are more than capable. Look at any Ag or commercial engine. 500 hr intervals on fleet spec oil. Without looking at my UOA I've done 13-14k mile intervals off of Mobil Delvac 1300. Regarding wear and metals my UOA looks very similar to yours. The difference is I'm paying $6 a gallon for my oil :D
 
Did you not see the HY-GUARD trademark on the spec table on the bucket? That tells me that whatever the HY-GUARD fine print is/says, Napa fits.

Copied from the current HY-GUARD brochure in the online parts book, it says in part:

"Note: Hy-Gard should be used in all applications calling for JDM J20C"

Since the brochure is current, I would say so is JDM20C.
 
That doesn’t mean that spec is current. It probably also says it’s equivalent to 303 hydraulic fluid which is 50 years old. Backwards compatibility is nothing new. Try looking up hygard specs.
 
For anyone freaking out about ensuring everything is perfect for warranty, do you change your AISIN fluid every 24 months? Or just every 30K miles?



As far as UOA, I wished fewer people used Blackstone.... In my experience their reports aren't even worth the money. They charge extra for TBN, they have horrible descriptions, and have criteria that doesn't match published OEM criteria. Every time I called them I was overly disgusted with how little their "experts" actually know. Reminded me of talking to WIX and listening to them explain why it was OK that their filters didn't meet OE spec, since microns are really small and 1 or 2 off isn't a big deal. Long story longer, I don't put any stock in anything I see with a Blackstone label... good or bad.

I got my last order of Mobile 3309 fluid from Summit Racing at a good price. With shipping and tax 6 quarts cost $40.78.
I had a few quarts left over from the 30K service., so I am ready for the 60K service.

I was looking at a few different '18 Tradesman 2 were SRW 2500, 1 was SRW 3500 all 3 have been on the dealer lot for 12-14 months, was thinking they should replace the fuel filters and dump the oil and filter, trans was that 24mo deal, it for sure is a concern of mine. Not quite sure they are game for doing that, but they are fine starting the warranty on day delivery.. I've gotten 5 or 6 vehicles from them so they might do it for me. On the fence about it in general since they have been sitting so long how would that affect the longevity. 2 have the AISIN but 3.42s, 1 has 68RFE w/ 3.42 I was doing some comparison on my 6.4l 66RFE RPMs which is same as the 68RFE ratio wise but I have 4.10s now.

I doubt they do much to them sitting like that.
 
Here's my last two UOA. Delvac 1300. $6 - $7 a gallon after rebates which Mobil does several months out of the year with all of their diesel oils. Price point is not my main concern for these type of purchases, I'm just showing that modern conventional oil is more than adequate. Note the 9 and 10 month intervals:eek: :D

Modern conventional oils are quite good. The gap between conventional and synthetic has really been closed. I still run synthetic for a couple of reasons, but can’t see anything wrong with conventional for most applications.

AMZ/OIL ATF is listed Mopar ASRC on their cut sheet.
Houston, we have a problem: the MoPar part number listed on the AMSoil advertisement doesn't purport to cross reference to the newest MoPar part number (05189966AB). The mention of ASRC doesn't cut it because it may be refering to the older *68 Aisin versus the newer *69 Aisin. If there is any doubt, it is my policy to err on the safe side. So, I won't be AMSoiling mine any time soon.

ASRC was not used before the AS69RC came out, it was called AS68RC fluid and when the AS69RC came out the fluid name was changed to ASRC to incorporate both transmissions. It's the same fluid.

05189966AB and ASRC are the same thing, so yes it does cross reference to it.
