Really? And there was me thinking that the number preceeding the W refered to the oils kinematic viscosity at 40*c, and the number proceeding refered to it at 100*c.
If anyone here can actually explain how the measurement of viscosity actually works and what the units are then please do.
Yes mate, but I'll leave you to wonder whether it's 10 degrees fahrenheit, celsius, kelvin or whatever.Andy wrote:Eek! Does that mean next time I'm out and the temp drops below 10 degrees I have to walk home?!
