The RVP is based on a test that measures vapor pressure of the gasoline blend at 100 degrees F.

FORBES: Why Spring Means Higher Gasoline Prices

Butane, which has an RVP of 52 psi, can be blended into gasoline in higher proportions in the winter because the vapor pressure allowance is higher.

FORBES: Why Spring Means Higher Gasoline Prices

The gasoline must have the proper octane, and it must have the proper Reid vapor pressure (RVP).
