mPAO, who is using it in their formulation?

[zfasts03]

What engine oils are using mPAO in their formulations? mPAO is supposed to be superior to conventional PAO, but significantly more expensive. Superior in regard to film strength and viscosity index.

I am aware of Driven and HPL No VII using mPAO. I believe Mobil 1 does in some of their upper tier lineup. Any others? Maybe/hopefully Amsoil sig. series?

Any downsides, beside the higher price?

go to synthetic base stocks then to formulation guide

Driven and mPAO are the only two I'm aware of that use it. It's usually used as a VII as the KV100 of mPAO is 65-300 cSt with a VI of 180-240. The oils that have it contain less than 10%.

more likely to find it in industrial lubes like for heavily loaded gear boxes - expensive and much of it a bit on the thick side

So it’s more of a garnish than even a main flavor. Even though it’s expensive, do you know if it’s more expensive than VII? Is it because it seems like it would be more miscible with PAO?

Or is it used because it has other crossover benefits that make mPAO more financially or operationally beneficial?

/flame suit on:
Hot Shots Secret FR3 supposedly contains mPAO (in unknown quantity) and Lavon Miller is their celebrity cheerleader testimonial so it can’t just be marketing… can it?

MPAO is used when you need an oil to be rock solid in terms of shear stability where a conventional VII polymer would otherwise fall short or to replace VII for an application where that VII may have a negative impact on the machinery or the rest of the formula. For example, VII will not solubilize in ester but mPAO will.
