Okay to mix Swepco 201 with Specialty Formulations

[Nitrox]

Since Specialty Formulations wasn't selling at the time, I bought some Swepco 201 tranny fluid. I still have about a quart of SF MTL-R in the container. Can I mix it with what's left of the Swepco gallon I am using?

Is it Porsche 911 ? I can tell you not to put any synthetic in a 915 transmission (I think years 1974-1986. Later year probably ok.) Swepco only according to the people that know in this application.

Ask me how much my lesson cost me.

It's for a Miata. The Spec Miata guys swear by the Swepco, but I've been using SF MTL-R. Almost out of MTL-R, so I got the Swepco. About a quart of the SF stuff left and wanted to know if I could pour it into the Swepco container and mix the two.

Why not PM Molakule?

I would just guess that it wouldn't be a problem - but that is just a guess based on most chemistries out there....

I emailed SF and didn't get a response. I'll PM Molakule next.
