70W oil is what weight after a run? (1 Viewer)

Anyone ever figure out the weight of 70W oil after a run? It'd be interesting to know how much the nitro dilutes it.

Doh! W is for winter, not weight. I read a wikipedia article that states it really is viscosity that the number indicates, according to a SAE rating system. So it goes in viscous and comes out less viscous. The real question is "how much does the viscosity change?"
