Ok, so for my current homework assignment I need to find a brand of motor oil that is a 10W 20 grade with specific gravity 0.91. The internet has failed me thus far.
Please help!

This might help, there's no such thing as 10W20
try either 0W20 or 5W20. I know nothing about oil lol

Hydraulics Lab Technical Memo. We had to measure the viscosity by timing how long a sphere took to fall in a graduated cylinder of oil and based on the density of the sphere and the speed we calculated the viscosity (to some massive degree of error I might add due to wall effects). Anyways, we had to report it in a technical memo and describe the type of oil based on the information we discovered (sg = 0.91 and vn = 7.998E-05 m^2/s)
Yeah - basically evil.

And that, gentlemen, is why I'm a biology major - spending my labs looking through a microscope
