Hi,

My apologies if this is in the wrong forum.

I will be building a refrigeration system for my PC. Pics can be found on www.silverplatinum.tk, under "Gallery" and "Xtreme Frosbite".

Now I will be using propane (R290) as a refrigerant. I have had a bit of a problem finding some cheap/small quantity oil for the system. But I managed to find some (today)

It is called Suniso Mineral Oil 3GS, which has a viscosity of SUS150, am I right? SUS 100 - SUS 150 is what I am after.

Now my two Questions:

1) Does 3GS=Sus 150?
2)What does add a charge of 10 psi static mean?
