What is winter mix gasoline?

Winter Gasoline In winter, gasoline blends have a higher Reid vapor pressure, meaning they evaporate more easily and allow gasoline to ignite more easily to start your car in cold temperatures. This blend is cheaper to produce, which results in lower gas prices at the pumps from late September through late April.

Does California use winter blend gasoline?

Every year refineries across California switch to producing summer blend gasoline in the spring, then winter blend gasoline in the fall. This switch changes the Reid Vapor Pressure (RVP) of California’s gasoline. RVP is a measure of the evaporation rate, or volatility, of gasoline.

Is summer gas different from winter gas?

Despite those higher prices, summer gasoline contains about 1.7 percent more energy than winter gasoline. Refiners constantly adjust their RVP to as high as 15 psi—higher than sea-level atmospheric pressure, which is 14.7 psi—to help the gasoline ignite more easily in colder temperatures.

Can you mix E85 with regular gas?

E85 gas is suitable for use in any vehicle designated as a flex-fuel vehicle by the manufacturer. Cars.com reports that flex-fuel vehicles are capable of running on both ethanol-gasoline blends and regular gasoline.

When to use winter blend gasoline at the pump?

Winter Gasoline In winter, gasoline blends have a higher Reid vapor pressure, meaning they evaporate more easily and allow gasoline to ignite more easily to start your car in cold temperatures. This blend is cheaper to produce, which results in lower gas prices at the pumps from late September through late April.

Can you blend butane with gasoline in summer?

Generally, the lower the RVP of a gas blend, the more it costs. For example, in winter you can blend butane, which is relatively plentiful and cheap, with gasoline. But butane, which has an RVP of 52 on its own, can’t be used in summer, when it would immediately boil off as a gas.

Do you use low volatility gasoline in the winter?

In frigid temperatures, higher-volatility fuel is essential and does not cause the smog effect it would in the summer. Using low-RVP fuel is a nonstarter in freezing weather; the engine won’t turn over or might misfire.

How is winter blend gas measured in California?

California might start using winter-blend gasoline early in a desperate attempt to bring down gas prices. But what is winter-blend gas, anyway? The different grades of gas are measured on a system of RVP, or Reid Vapor Pressure, which is measured in pounds per square inch (PSI). The higher the RVP number of a particular gas blend,…
