Does anyone know what is kinematic viscosity in gm goodwrench 10w30 oil? At 40c. and 100c.? thanks.

GM should.

Most 10W30's are 68-70cSt @40*C and 10.5-10.8cSt @100*C

Even if an oil is listed as being XcSt @40 or 100*C, there are still differences in final viscosity between batches. Use the number the manufacturer gives as an estimate.
