Re: oil thicknesses?
We do have oil experts on here, But I have not seen well oiled post for some while.
Viscosity is a funny thing, it is a measure of the shear forces required to allow movement of the fluid.
The method we used was to time the decent of a ball within a measuring tube. and I seem to recall the unit of measurement was the stoke or centistoke
