Have you thought of getting a couple UOAs performed to establish a trend? That’s the usual recommendation for safely extending the OCI. Stick with the Amsoil Signature Series. One of the best PCMO to be had.

yes i was tempted to do UOA ..
but kept thinking all metals are gonna be
( normally high ) because engine still in breaking in period ... iron , aluminum, copper ,
(+silicone even) etc .. are all gonna be high
.. thought maybe id start UOA after 20k
establish a "trend" .. then run with it ..

It’s perfectly fine to wait, but earlier UOAs can spot the downward trend to indicate it’s past the break in period; while still determining if the lube is suitable for continued use or not. It gets you the data sooner.
may i ask another question please,
during my search found out that
HONDA OEM 0W-20 ( full synthetic)
has 10.3 Cst@100 viscosity !!!!!!
A- how come it's still classified as 0W-20!??
( Way over the 9.2 cst !!)

you're absolutely right !!!
im kinda regretful i didn't!!!
didn't know better then ... and knowing what i know now i would've done it !
Seeing that we have gone off-topic, maybe best to create a new thread on this subject. Doubt that their oil is out of grade.

What has you thinking that it is? I am genuinely intrigued. Trying to decide which oil to go with on my wife's '24 Mazda CX-5 after the second free dealer oil change.
I also see that the Dexos license # is the same with the new SQ data sheet. In fact, going back to at least 2022, the data sheet shows the exact same license #. I assume this means the oil has not changed? All other properties of the oil listed are also identical (flash point, viscosity, etc).
It’s not really a big issue because as others have noted it’s probably the same formula. Just wish Amazon would be a little more specific. FYI if you contact Amazon customer service chat they will offer a partial refund to compensate for the different bottle.
The ones that say 20k were discontinued 1 year ago I think, I'm guessing it's old stock. Though a year isn't gonna do anything to reduce the service life. Was is directly by amazon or a third party? Must've been a third party unless amazon was processing stock first in first out.

Amazon direct and delivered in one day. No big deal just noting so.
Later I can look for the date...
$28 no big deal with subscribe.
The old stock pile must be hugeeeee
. Some folks report even Walmart has been shipping some old bottles too sometimes. Even though it was discontinued maybe Castrol kept using the old labels/ bottles on an attrition basis and slowly rolling over to the new style depending on the weight. Either that or they simply have the EP as lower priority. Due to the fact that the black Edge bottles almost instantly overnight have been new style with no lack of supply.

As much as everyone loves the convenience of ordering things from Amazon, in cases like this you’re better off buying this oil in person so you know exactly what you’re getting. I know that most people on here enjoy having the latest formulas of oils.
I have an order of 6 jugs coming tomorrow from Amazon. FYI, the listing does say that you may get the 20,000 mile OR the 25,000 mile bottle. Do your 20,000 mile bottles still list the MB 229.71 spec? Castrol has conflicting data sheets, as not all of the sheets spec 229.71 but every bottle I’ve seen with API SP, even the older 20,000 mile bottles, do have the 229.71 spec.
EDIT: never mind, I see you bought 5w20. I bought 0w20. Although some have still reported recently that they also got old stock of the 0w20. Must be a slow-moving product. Castrol changed their logo over a year ago! On the opposite end, I was looking at bottles of PP at Walmart the other day, and all of them were from this past December or January.
The 0w20 EP is unobtainium in person, unless you want to pay auto parts store prices. It’s even out of stock often online, or priced super high.
