M1 ATF Discontinued?

Guys,

I saw that Advance Auto Parts had Mobil 1 ATF on clearance for $1.75. They were saying it was discontinued. I now see that Auto Zone has it on clearance for $6. Is this product (the Dex III ATF that has been around forever) truly being discontinued by the manufacturer?

I've used this since my first ATF drain/fill on my 2002 Toyota Tacoma that I bought brand new 20 years ago. I have 252K miles on it now and do a drain/fill every 50K. So I bought enough on clearance to have enough for my 300K mile drain/fill. I'm working from home these days so at that rate I may not put another 50K miles on my truck for 10 years, so I didn't want to buy more than that.

Anyway, if M1 ATF *is* being discontinued and there are others out there with older vehicles that call for the Dex 3 spec that have been using it, what are you planning to switch to? I may or may not ever need to switch to something else myself at this point, but I'm curious! Maxlife? Some Dex VI?

I used it a lot back in the day when you could get a "deal" on a case of 6. But then I switched to DEXRON-VI since it was a little cheaper. But then I switched to Maxlife because it was a littler cheaper still. The Mobil 1 product seemed like a good one but the cost was ridiculous compared to the alternatives that seem just as good. Yes I am a Maxlife convert.

Looking at your signature, I can see you have older (and higher mileage) Toyotas than mine, so that's good to know! :) I know Dex VI and Maxlife are both lower viscosity than the M1 ATF so it is good to know you've put lots of miles on it.

What about Mobil Delvac 1 ATF? Carries the TES-295 spec for Allisons and used to be licensed for Dex III. Also the same as Castrol TranSynd.

Been running it in two higher mileage 4L60E, a 4L80E and in a mid-2000s GM Hydroboost with great results.

So does anyone *know* if the M1 ATF *is* being discontinued? Their website still shows it--I'm only basing this on some auto parts stores' clearances.

Unless someone works for Exxon, most comments will just be speculation. It could be as simple as they're releasing a revised/improved version but that doesn't seem likely for an older-spec product. Does Mobil 1 offer a multi-vehicle ATF ? If so, they might supersede the ATF you're talking about to it.

Essentially they have these 2 ATFs:



What's strange is that if you look at the parent page (https://www.mobil.com/en/lubricants/for-personal-vehicles/our-products/automatic-transmission-fluids) they show the wrong bottle for the old (non hp) version that I'm asking about.

I tried to send an inquiry through their website but it is just clocking when I hit submit. Looks like it isn't going to work.

For someone who is a stickler about approvals, this seems like an unusual departure from your usual position.

Which approvals am I disregarding?
In the OP's case, none. But I was surprised that you used it in your Tiguan since it does not carry any OEM approvals:

I got a reply from Mobil and they said:

"Our Mobil 1 Synthetic ATF is an active product."

So their official position is that it is not currently discontinued.

It could be as simple as a packaging change. That SKU might be discontinued, but not the actual product.

Our GM approved bulk motor oil changes part numbers a lot. On the 0W20 I have an older number memorized, but it changes to the new number when I bill it out.

Well, most OEMs don't have an approval for transmission fluid, unless I'm mistaken.

Well with all the oil companies trying to make a ATF/CVT combo fluid it kinda seems they are pushing out the other fluids. I know CVT from many parts stores isn't in a dedicated shelf spot anymore or at all. I scored lots of 0w20 Castrol Magnatec and CVT fluid because most cars weren't new enough to need it or didn't bother self servicing so it was liquidated.
