5w30
5w30 is a multi-grade oil so at different operating temperatures, it has the viscosity of different grades of oil. It goes something like this: At low temps or cold startup the oil behaves like a 5 weight oil at that temp. At high temps or normal operating range, the oil behaves like a 30 weight oil.
Just for your information, oil viscosity is measured at 100 degrees? I think. Correct me if I'm wrong, could be higher.
So this means that 5 weight oil at "100 degrees" is a whole lot thinner than 5 weight at 40 or 50 degrees.
