At What temperature will air get a larger kinematic viscosity than crude oil?

Please explain step by step.

I believe we have compare the viscosity of air and the oil using the formula: kinematic viscosity = dynamic viscosity / density

2. Relevant equations

inematic viscosity = dynamic viscosity / density

density = pressure / RT

3. The attempt at a solution

so what I did so far was make the kine viscosity (of air) = kine viscosity (of oil)

dynamic viscosity / (pressure / RT) = dynamic viscosity / (pressure / RT)

NOW I AM STUCK!!! I do not know what values to use for dyn viscosity, pressure, R. I know I have to solve for T to get the answer.

(the answer is greater than 7 but no clue how to reach there w/o those values)
