Anybody hear about Group III 10 cSt ? What will be the major application for this base oil?

Insulating fluid in transformers, maybe.
motor oil
Thank for the answer. But to what extend a group III 10 cSt can be used in motor oil (for monograde) or industrial lube ? Blender will be using lower price 500N from group I and group II base oils. Any typical application for replacement of PAO 10 cSt ?
Your confusing me. I hope you are not thinking that by mixing Group I and Group II oils you get Group III oil, are you?
what exactly do you want to know?
a 10cSt oil would work well for a PCMO aswell as a HDEO.
it is to thick for insultating oil and to high dollar for most "industrial" oils.

Dear People
First of all, you should clear the temperature value for viscosity.
When you say 10 Cts, are you refering to 40 °C?, or are you refering to 100°C???
If you are talking about motor oil, it is very probable that the complete referece should be 10 Cts to 100°C, but if it is motor oil, you should indicate the viscosity in SAE Grade.
Maybe you would like to say SAE 10, or may be it is a monograde SAE 25W (equivalent to 10 Cts to 100 °C).
Please, see the table in

ASTM D 3487, Standard Specification for Mineral Insulating Oil pretty much govern in this industry field, and its tables list viscosity for both Type 1 and Type 2 oils at max. 12 cSt @ 40 degrees C. However, Group 3 oil might not be the best solution for transformers if its VI is more than 80, which I think it is. And also, the solvency might be deficient as well (too high Aniline Point).
It is common to call out PAO and GPIII in vicosity @100C that is the standard vis temp for them as a base oil.
Example a GPIII base oil maybe 4,7,or 10 cST @100C that is how they are called out so a 10cSt oil @100C is perhaps a ISO VG grade 100 at 40C way to high in vis for most common "insultating' oils

Thank you for all your answer. Base on the above reply from all of you. The conclusions is as follows :-
Usage of Group III 10 cSt (100C)
- Motor Oil 15W/40
- HDEO (higher grade)
- Insulating oil
- Tranformer Oil (not a good choice)
- Industrail oil (to expensive)
Any nichie product that can be product with Group III 10 cSt ?
