Is there a summer blend gasoline?
Summer-blend gas has a lower RVP to prevent excessive evaporation when outside temperatures rise. That evaporation can cause vapor lock in an engine on hot days and contributes to unhealthy ground-level ozone and smog levels. Summer-blend gas contains 2 percent butane, but that percentage is higher in the winter blend.
Why is summer blend gas more expensive?
Summer-blend fuel is also more expensive to make than winter-blend fuel. First, the production process takes longer and, second, the overall yield of gasoline per barrel of oil is lower. These complexities add as much as 15 cents per gallon to the cost to produce these higher-grade fuels.
What is summer blend fuel?
Summer Gasoline Refiners reduce the chance of gas evaporation in your car during the summer by producing gasoline blends that have lower Reid vapor pressure (RVP), or lower volatility. These blends vary from state-to-state, region-to-region due to RVP state regulations. They also vary by octane level.
Does summer blend gas burn faster?
In terms of gas mileage, you get better mileage on summer blends than winter blends because the summer blend gasoline has about 2% greater energy value than winter blend. So the gas you are using now most likely has a lower energy value than the gas you used in the summer.
What cars use E15 gas?
What vehicles may use E15? Model year 2001 and newer cars, light-duty trucks, and medium-duty passenger vehicles (SUVs); and flexible-fuel vehicles (FFVs) are allowed by the EPA to use E15.
Is there different gas for summer and winter?
Despite those higher prices, summer gasoline contains about 1.7 percent more energy than winter gasoline. Warmup times aside, that’s why you could measure reduced fuel economy outside the summer months. Winter gasoline varies widely in volatility throughout the season.
Is summer gas different than winter gas?
Under pressure A primary difference between winter- and summer-blend gas is their Reid Vapor Pressure (RVP). RVP is a measure of how easily the fuel evaporates at increased temperatures. The higher the fuel’s RVP, the more easily it evaporates. Winter-blend fuel requires increased RVP.
Does winter-blend gas reduce mpg?
Refineries switch to winter-blend fuel in the fall, which evaporates more easily at low temperatures to aid in starting. It also helps the engine run more smoothly in frigid weather. Unfortunately, winter-blend gasoline contains less energy than summer-blend gas, reducing mileage.
What’s the difference between summer blend and winter-blend gas?
The main difference between summer and winter gas is that winter gas has a high Reid Vapor Pressure, or RVP. Gas with a higher RVP evaporates more quickly at a given temperature.
Does summer blend gas reduce mpg?
In fact, the Environmental Protection Agency says summer-blend gas contains 1.7% more energy than winter gas. Winter-blend gasoline contains less energy than summer-blend gas, reducing mileage. In fact, the Environmental Protection Agency says summer-blend gas contains 1.7% more energy than winter gas.
Can you use summer gas in the winter?
Can I use summer gas in winter? It’s best to avoid using summer blend gas in winter. That’s because summer gasoline is less volatile and doesn’t evaporate quickly, and these factors can cause trouble starting the engine in colder months.
Is E15 better than 93?
With E15, the extra ethanol boosts the pump octane rating of the fuel several additional points compared to 10 percent ethanol gasoline. The pump octane rating may be as high as 98 with E15 if it is blended with a high grade gasoline, or as low as 91 to 93 octane if it is blended with a low grade gasoline.
Will ‘summer blend’ gas prices balloon again this summer?
AAA spokeswoman Jana Tidwell says summer travel and the annual upcoming switch to ‘summer blend’ gasoline will balloon prices again.
How much does summer blend fuel cost?
Cost for your wallet: According to NACS, higher-grade summer blend fuel can add up to 15 cents per gallon to the cost of your fill-up. This excludes the increased cost due to summer fuel demand, which can vary between 5-15c/gal, depending on the region. More stringent requirements (like California) can mean an even higher cost.
When do refineries switch to summer blend gasoline?
March through April is the transition season at refineries as they switch over to summer blend gasoline. In case of a supply shortage and more demand for summer blends, refineries often produce more.
What is winter blend gasoline and how does it work?
Winter blend gasoline has a higher RVP which means it evaporates more and allows gasoline to ignite more easily to start your vehicle during cold temperatures. It’s much cheaper to produce which is why gas prices are less during this time of year, which is usually September until April.
