What's a good way to test viscosity in oil samples? (other than using bbs or bubbles)?

I'm doing an engineering project on sampling and testing oil for viscosity. I was wondering if anyone knew of any other good methods other than dropping ball bearings or blowing bubbles through it? Thanks in advance :o)What's a good way to test viscosity in oil samples? (other than using bbs or bubbles)?
Get a viscos meter, which works by your placing a drop of oil on a glass screen which is then viewed through a prism, done a microscope tube and the viscosity can be read of against a clearly visible scale.


Easy peasy, used all the time in drawing down machinery to ensure consistency of the lubrication and preventing unecessary shutdown and lost production...What's a good way to test viscosity in oil samples? (other than using bbs or bubbles)?
A quick trick I use in the field is to insert my pencil half way and time how long it takes to drip off of the tip. I can sort out viscosity quickly with that for simple comparison.
Use a viscosity cup. This is a calibrated cup that looks like a small plastic funnel, which you fill and record the time your fluid takes to pass.
