VRP with Moly E.P 132

[Cmobile]

Here in the U.S., VRP 5w-30 is the highest viscosity i see.
Would like to run a little higher viscosity in a 3.0L turbo, Volvo T6. While staying with VRP for cleaning. More specifically, I'm interested in a slightly higher HTHS more so than viscosity at 100C.

So, right, wrong or indifferent, I added 1 bottle of Schaeffer's Moly E.P. 132 to the sump which holds 8 qts.

My question is, will the Moly E.P. 132 increase HTHS my a measurable amount?

I could add 2 qts of 132 and be in the treatment range. 16oz to 4-5 qt. Sump.

Thoughts?

1 pint of EP to 5 qts oil will usually thicken the visc 1 to 2 grades. 1 pint to 8qts would be in the 40grade range. I don't know about hths increase but I wouldn't worry about it. EP is about twice as thick as Lucas and is in the ~ 200visc range at 100°c, iirc. You would be fine with just the one bottle. You can find a visc calculator if you want to do the math properly.

250-290cst @ 100°c

Sent an inquiry to Schaeffer Manufacturing about an increase in HTHS by adding 132. I received the following response:

""Yes, the 132 will increase the HTHS viscosity as well as standard viscosity values.""
From a technical support engineer.

I think I read that Valvoline Restore & Protect has an HTHS of 3.2.

Wlk,
Thanks for your response and provided info.

Probably not gaining anything by adding it, other than to curb some OCD.

I use it in my vehicles, it cured a valve tap in my lawnmower & my buddies Kabota and I would recommend it if needed.
I have thought about doing the same thing in my latest vehicle as you did. Wish VRP would come out w 10w40 but so be it.

It will increase HTHS quite a bit I suspect.

Just realized I had a typo.

This should read pints. Two pints (1qt)
Sorry

So if I'm running 15w40 on my 8.9 quart system and use one pint of that Moly it would raise it to a 25w50? Or maybe a 20w50? I used it once in my car and had 15w50 in there and it lost power. I wanted to try it again I guess. Idk I just feel does it actually protect more w antimony or is it snake oil. I don't see an issue with running one pint of this with 15w40. It falls for 0w40 on my engine but it's hot Texas weather and I rarely see cold temps

It will take it to an xW50 at least. Google visc calculator and you can plug in the numbers to find the exact cst if interested. If you have a 9qt capacity and really need a thicker grade 1pint may take it to the lower end of a 50grade, depending on the xW40 you start with. Or run M1 15w50 if you want to just grab something from the shelf. Not snake oil either, lots of interesting info on here about it, especially from years ago.
