Re: Marine Lubrication
BTW, you can get the ° symbol by holding alt and pressing 0176. Or run "charmap" and insert it from there.
How do you determine what temp a particular weight oil is good down to?

Ever since Mobil lost their lawsuit against Castrol (they objected to the fact that Castrol "synth" was made from Group III base stock instead of being truly synthesized), and the court decided that the word "synthetic" was related to oil performace, not exactly how it was made, most manufacturers of "synthetic" oils switched to using Group III base. Mobil 1 was one of the last holdouts.
