Anybody ever use nitro methane oil as an additive????

I think I'll limit any comment to "that's fantastic." I can't think of a single good reason to spend $9 like that. Oil doesnt average its protection. Your greatest protection is only whatever the lowest level oil you put in is. So if you combine 70wt with 30wt, you dont get 50wt protection. You get 30wt protection. Think of oil molecules like golf balls. If you take 100 white ones, and then add 20 orange, the whites don't get an orange tinge. You get whites witha few oranges floating around...
