Amsoil 75w85 for 2019+ ST PTU

[boostededge]

Since the 2019+ ST's call for 75w85 has anyone tried the Amsoil for a decent chunk of miles?

That is all!

I have never used AMSOil products so I can't say.

 

The PTU calls for Motorcraft XY75W85QL  ( Synthetic ), which is ridiculously expensive.  

 

As an option, you can use either one of these.  I use the Motul.

I went with the Amsoil SVG 75w85 in the PTU. The guys on Bobistheoilguy said the 85w would run ever so slightly cooler than a 75w90. And it makes sense to put a better than factory fluid back in.

 

Theres a big Gear Oil Test thread where they test all the popular 75w90 gear oils on the market and the Amsoil came out on top of everything for the most part. Flash point, 4-ball wear, etc.

About 5 years ago I switched all my vehicles over to Amsoil SVG.

 

I did this based on the widespread independent reviews that included lab results.

I agree. When it comes to parts you can't go wrong with OEM. It's a no brainer.

But when it comes to lubricants, in many cases there are better options. 

And there are some good ones: Amsoil, Red Line and Motul are by far the best. 

The key is Full Synthetic. I plan on going with Red Line for my PTU/RDU. 

Any suggestions from you guys on the transmission fluid? That's the one I haven't done any research on.
