Engine oil viscosity in centipoise?

Recommended Posts

Hi all,

 

Not strictly a car related a question but here goes anyway. I've got a viscosity meter down in the lab at the moment which I need to calibrate before I can use. You can buy viscosity standards from laboratory suppliers but they're hugely expensive, so I was thinking . . .

 

Is there a way I can convert from engine oils grade (ie 15W/40 etc) to poise or centipoise (the metric standard unit for viscosity), which is what the machine reads in.

 

Alternatively, if someone has a bottle of multigrade sitting next to them at this moment, could you search around on the label and see if it has any viscosity readings on it in poise, kilodynes, anything really. I'd check myself but I don't have any oil with me and I'll have to order the standards today if I can't get any oil info . . .

 

Cheers!
