Amsoil's Base Stocks, who supplies them?

[donnyj08]

Do we know who Amsoil purchases their basestocks from? I've heard in the past that they purchase them from Exxon/Mobil.

Do they still purchase from Exxon/Mobil or do they also purchase from Sopus, chevron, or other Refiners?

Some of the Specs for SS and PU SN are very similar in the 5w30 and 10w30 grades. Is Amsoil still using mostly PAO or are they possibly purchasing some GTL stock also?

I chatted with a jobber for Amsoil who told me they still get a lot of their base stock from Mobil. Since they now have broadened the line to include Group III blends, I would suspect they get base stocks from others as well. I am pretty sure the SS stuff is primarily PAO. The XL line I believe is a PAO/Grp III blend, and the OE line is primarily Grp III. But they also have different levels of TBN and other additive formulations as well in each of those product lines.

I was under the impression that OE and XL used the same base stock, but XL had a stouter Additive package.

The one I'm wondering about is the SS oil

Pablo? Any insider perspective on this?

It's secret...and apparently not (all) Mobil.

Well not many actually make synthetic base oil, but Mobil doesn't supply all the base oil (Common internet myth). Amsoil purchases from various sources. Both base oils AND additives make an oil.


By not having API certification, they can shop around.

If you're talking about the old Pennzoil Ultra (which I don't believe was GTL), I can see some similarity to Amsoil SS in the 5W30 grade. Not so much for the new Pennzoil Ultra Platinum, which has a higher NOACK % than the new Pennzoil Platinum.

To me, that means that their formulation can and does change on a regular basis. How do you know what you're getting?

I would guess that the Mobil SN formulation from 2011 is the same as the Mobil SN formulation from 2015.

Yes, the old "low NOACK" formula, had similar specs.

Also if you look at PQIA. Amsoil OE and MSS could be interchanged. Add pack and NOACK are nearly identical within statistical error.

I believe this is probably correct.

They do tweaks. You can guess by looking at when the MSDS was updated.

Amsoil OE actually looks incredibly similar to Super Tech in that 5W30 testing!!!
I think the one big difference is that ST had no moly.

A little

here (what bitog thread isn't!

), but for a brief period before the re-branding/re-labeling, Pennzoil was indeed using GTL base stocks circa 2013 and confirmed this in a Q&A.

Very true. The MSS is almost the same. It even contains the same concentration of moly. Both ST and MSS are Dexos oils so definitely great lubes.

Are they still using GTL basestocks in their conventional oils?

These two look very similar.

I have experience with Amsoil OE, I mainly was curious about the SS basestock. I realize from a performance standpoint it really doesn't matter as group III oils perform excellent.
