Hi guy,
I don't find someone talking on this (Or maybe I missed some post). I have a question about "W" number. As we know that it was rated for low temperature viscosity and I don't need to care about this number if I live in hot country. But, I would like to know what kind of chemical/additive they add to lower W number.
And if they add it. In my opinion, it should be something that affect oil characteristic at high temp too (Or not?). It might look too serious to choose an oil but I'm new to this role and would like to learn about this.
