I use this oil in my air-cooled junk engines (lawnmower etc.) It is good for what it is. I have some data on hand that may be out of date that shows the pour point at -33 deg C, the kinetic viscosity at 40 deg C as 82 cSt, and the KV at 100 deg C as 10.3 cSt, all of which show the oil to be a rather thin straight 30-weight.
