Here in the U.S., Valvoline Restore and Protect 5w30 is the highest viscosity i see.
Would like to run a little higher viscosity in a 3.0L turbo, Volvo T6. While staying with Valvoline Restore and Protect 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 and 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 Valvoline Restore and Protect would come out w 10w40 but so be it.

It will increase HTHS quite a bit I suspect.
 
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.

I currently have about 3300 miles on Valvoline Restore and Protect with 2 pints of Schaeffer's #132 Moly E.P. in an 8qt sump.

No promises here, but once I move to Texas in the coming weeks, I hope to find a shop that will change my oil and take a sample I can send off for UOA.
Won't mean a whole lot as I don't have UOA history on this vehicle, but maybe it will give an idea of viscosity.

Won't have a place to change my own oil upon arrival to TX.

Which Analysis co? Speed D, or Polaris Labs?

The volvo 3.0l turbo will be transported via truck transport. So the OCI may be around 3.6k- 4k miles by the time I can get it sampmled.

I was yet to see a UOA with a decent oil and the Moly EP. What was the data that backed up it's additive properties? I'm all ears. Want to learn about the stuff. I like running a slightly thicker oil than 0w40 in my twin turbo V8 which is heavily modified. I was running straight 15w50 in it which is fine but I like the characteristics of the 15w40 full synthetic diesel oil I'm buying as it's cheap and I did a UOA on it and it's great oil. That's super tech 15w40 full synthetic diesel oil btw.

As of right now I have been adding 2 quarts of Motul 15w50 high zinc and phosphorus 1800+ PPM in my oil as an "additive" but I'm happy to dump that idea and add one pint of this instead of it has extreme friction and protection properties

Here is a screenshot of what's in it and here is the link for the thread it came from. It will raise the viscosity a grade a good bit, so just do a google search for a viscosity calculator and you can figure out where it will be for your oil.

Part of the magic with 132 is the carrier oil.

Any updates on oil analysis?

But do we add the one pint per 4-5 quarts per Schaeffer's recommendation? Like I'm running a tuned twin turbo V8 Mercedes and it calls for 0w40. But I run 15w40 or 15w50 mixed with 40 and it is fine. But if I added the whole quart of Moly it got to the point where engine felt sluggish especially at low roms. Turbo spooling was sluggish imo. I didn't risk it and drained it. I was running 15w50 with 2 quarts of 20w50 VR1 FS in that OC and added the recommended Schaeffer's 1 quart. It was way way too thick. Prob a 25w60 or more. Engine hated it. So I run now 15w40 supertech FS diesel oil and it's a nice flowing oil. Runs fantastic. I was adding motul classic 15w50 2 quarts to my oil as an additive. It has high moly and zinc. 300 on moly and 1800 zinc. I did an oil analysis and came back fantastic. Blackstone said. Run it 6500 miles and we will come back to it. I ran it 5k miles and that oil is fantastic btw. Supertech is excellent oil.

That's quite the fine-tuning of oil grade (including winter rating), and going from "hated it" to fantastic.
