i give you guys using such low weights credit, considering 10-30 in summer is like water!! thats why i used thicker weight in summer, started back with my first rotary in 1998, and every rx7 since then.

I believe Mazda has more experience then anyone or nearly anyone in the world on this topic but the engineering data is trade secret. I'm sure the compromises are really the limiting factor for longevity

Ah, I thought your were talking about effects of film shearing on the lubricated parts, not the oil. In that case, I think we're thinking along the same lines. If we have to make a compromise, go with that which favours the rotor seals, which means thinner oil.
