Did you know that summer blend gasoline can reduce smog-forming emissions by up to 15% compared to winter blend gasoline?
Summer blend gasoline is a type of fuel specifically formulated to perform optimally during the warmer months. The main difference between summer and winter blends lies in their volatility, or the fuel’s tendency to vaporize.
Summer blend gasoline has a lower Reid Vapor Pressure (RVP), which means it is less likely to evaporate into the atmosphere, reducing the amount of smog-forming emissions. In contrast, winter blend gasoline has a higher RVP to ensure the engine starts easily in cold temperatures.
Understanding Summer Blend Gasoline
The summer blend gasoline has a lower RVP, typically around 7.8 to 9.0 psi, which measures how easily gasoline evaporates at a given temperature. A lower RVP indicates that gasoline is less likely to evaporate during hot temperatures, making summer-blend gasoline perfect for hotter months.
You might be wondering why is summer blend gas more expensive. Well, the answer lies in its manufacturing process. Summer blends contain fewer light hydrocarbons like butane, which are more volatile. This makes the fuel less prone to evaporating, which helps reduce emissions of VOCs. To compensate for the reduced amount of lighter hydrocarbons, summer blends may contain higher levels of aromatic hydrocarbons, which are less volatile and contribute to the fuel’s energy content.
It also contains additional detergents and additives that help keep the engine clean and running efficiently. These additives improve combustion and reduce deposits in the fuel system.
The Environmental Protection Agency (EPA) typically mandates the switch from winter blend gasoline to summer blend gasoline from June 1 through September 15. When does winter gas start, might be your next question. The onset of winter blend gasoline starts from around mid-September, but the dates can vary between states.
Many people don’t know what states have summer blend gasoline, even though it’s required in many US states, including California, Illinois, New York, and New Jersey, to reduce air pollution during the warmer months.
Using winter blend gasoline during the summer months may result in increased evaporation due to its higher volatility. This leads to reduced fuel efficiency and engine performance issues like vapor lock, where the fuel turns into vapor before reaching the engine.
Although the difference is slight, summer blend gasoline’s higher energy content can lead to better fuel economy compared to winter blends. The lower volatility and slightly denser fuel provide more energy per gallon.
Top Tips for Using Summer Blend Gasoline Efficiently
Tip 1: Maintain Proper Tire Pressure
Under-inflated tires have increased friction against the road while generating more heat, known as rolling resistance, which requires the engine to work harder and consume more fuel. Correct tire pressure ensures optimal tire performance and improves handling and braking performance while extending their lifespan. Tires with the right pressure also provide a smoother and more comfortable ride.
Steps to Check and Maintain Tire Pressure:
- For the most accurate reading, check tire pressure when the tires are cold, typically before driving or after the vehicle has been parked for a few hours.
- Unscrew the valve cap from the tire valve stem.
- Press the gauge firmly onto the valve stem and hold it until you get a reading. Note the pressure reading.
- Compare the reading to the recommended pressure.
- If the reading is lower than the recommended pressure, attach the air compressor nozzle to the valve stem and add air in short bursts. After each burst, check the pressure with the gauge until the tire reaches the recommended pressure.
- If you accidentally over-inflate the tire, release some air by pressing the center pin inside the valve stem with the gauge.
- Once the tire is at the correct pressure, replace the valve cap to protect the valve stem from dirt and moisture.
- Repeat the process for all four tires, including the spare if your vehicle has one.
Tip 2: Regular Vehicle Maintenance
Maintenance includes oil changes, air filter replacements, and spark plug checks.
The oil change frequency depends on the type of vehicle you own, the load on the vehicle, and how many miles it has run. However, the general recommendation is every 3,000 to 5,000 miles.
Next up, we have air filter replacement. Replace your air filter every 15,000 to 30,000 miles, but this schedule can vary depending on driving conditions (dusty environments may require more frequent changes). A clean air filter allows for better airflow into the engine, optimizing the air-fuel mixture and combustion process.
Worn-out spark plugs can also misfire or cause incomplete combustion, leading to reduced fuel efficiency, which is why it is important to replace them every 30,000 to 100,000 miles.
Other essential maintenance tasks that contribute to overall vehicle efficiency and performance include:
- Regular inspection and cleaning of fuel injectors
- Properly functioning brakes
- Ensuring the radiator and coolant system are in good condition to prevent overheating.
Tip 3: Use the recommended grade of motor oil
The right oil grade contributes to the engine’s longevity by providing optimal lubrication, reducing sludge buildup, and maintaining proper engine temperature. It provides the right balance of viscosity and performance to protect engine components from overheating and wear and tear.
Here’s how to find the right grade of motor oil:
- Consult the owner’s manual.
- Visit the manufacturer’s website.
- If you’re unsure about the right oil grade, get advice from a trusted mechanic who can provide recommendations based on your vehicle’s needs.
- Decide whether you need synthetic, semi-synthetic, or conventional oil based on your vehicle’s specifications and driving conditions.
- Ensure the oil’s viscosity rating (e.g., 5W-30) matches the recommendation. The first represents the oil’s flow at cold temperatures (W for winter), and the second represents its flow at high temperatures.
- Choose high-quality motor oil from reputable brands that meet industry standards (e.g., API, SAE).
Tip 4: Drive Smoothly
Aggressive driving, characterized by rapid acceleration and braking, involves operating the engine at higher RPMs (revolutions per minute), which consumes more fuel.
Moreover, it stresses engine components, transmission, and other parts, leading to more frequent repairs and reduced vehicle efficiency over time.
- Accelerate gradually and maintain steady speeds.
- Look ahead and anticipate changes in traffic flow or signals. Gradually adjust your speed rather than making abrupt changes.
- Apply the brakes gently and gradually to avoid hard stops.
- If you’re stopped for more than a minute, consider turning off the engine.
Tip 5: Reduce Excess Weight
For every additional 100 pounds of weight, fuel efficiency can decrease by about 1-2%. This reduction in miles per gallon (MPG) means you’ll need to refuel more often, increasing overall fuel costs.
To reduce the likelihood of such circumstances, you will need to reduce the vehicle's overall weight.
Start by regularly cleaning out your trunk. Avoid overloading the vehicle with luggage and other items. While it’s important to keep enough fuel in the tank, carrying a full tank always adds weight. Consider filling up to half or three-quarters of a tank if you’re driving locally and can refuel easily.
Even though carpooling is generally good for fuel economy, be mindful of the number of passengers and their belongings.
Tip 6: Minimize Air Conditioning Use
Running the A/C can reduce fuel efficiency by up to 20%, depending on driving conditions, outside temperature, and vehicle type. This means you’ll need to refuel more often, increasing overall fuel costs.
Of course, the A/C is an essential component of your vehicle and is added to enhance your comfort while driving. You will inevitably use it while on the road, but you might as well use it more wisely.
Avoid turning on the A/C immediately after starting the vehicle. After you have switched on the AC, switch to recirculation mode to keep the cool air inside and reduce the workload on the A/C system once the interior is cool enough.
Whenever possible, park in the shade or use a car cover to keep the interior temperature lower. Use sunshades on your windshield and windows to block direct sunlight and keep the interior cooler.
Check refrigerant levels and have the system serviced regularly to prevent it from working harder than necessary. Keep the cabin air filter clean to ensure maximum airflow and cooling efficiency.
Tip 7: Plan and Combine Trips
Running errands efficiently can save time, fuel, and stress. Start by listing all the tasks you need to accomplish, then organize them by location and priority. Here are a few ideas to give you a headstart:
- Use GPS or mapping apps to plan the most efficient route that covers all your errands with minimal backtracking.
- Take note of peak traffic times and plan your trips during off-peak hours to avoid congestion and reduce idling time.
- Use apps to locate the nearest stores, check inventory, or order online for in-store pickup, saving you from unnecessary trips.
- For short trips, consider walking, biking, or using public transportation. This saves fuel, provides health benefits, and is more cost-effective.
Tip 8: Use Cruise Control
Cruise control is most effective on highways and freeways where traffic is light and speeds are relatively constant. Avoid using it in heavy traffic, on winding roads, or in adverse weather conditions.
- Set it to a speed that is within the speed limit and comfortable for the road conditions. Speeds between 50-70 mph are generally considered optimal for fuel efficiency on highways.
- On hilly or curved roads, manually controlling the speed might be more efficient and safer.
- Even with cruise control engaged, stay alert and keep your hands on the steering wheel.
- Combine overdrive with cruise control to reduce engine RPMs at higher speeds, further improving fuel efficiency.
Lastly, be aware of the limitations of your vehicle’s cruise control system. Advanced features like adaptive cruise control can help maintain a safe distance from vehicles ahead, but standard systems require constant monitoring and manual adjustments as needed.
Tip 9: Monitor Fuel Economy
Significant drops in fuel economy can indicate underlying issues with your vehicle, such as a clogged air filter, low tire pressure, or engine problems. Early detection can prevent more serious and costly repairs.
Fuelly, Drivvo, Simply Auto, and Simply Fleet are popular apps that allow you to track fuel consumption, maintenance, and costs. You can log fill-ups, monitor fuel efficiency over time, and set reminders for vehicle maintenance.
Many modern vehicles come equipped with onboard computers that provide real-time fuel economy data. Use the trip computer to monitor average fuel consumption and adjust driving habits accordingly.
On-Board diagnostics (OBD-II) devices can be plugged into your vehicle’s OBD-II port to monitor various performance metrics, including fuel economy. These devices often come with companion apps for detailed analysis.
Tip 10: Opt for Fuel Efficient Routes
Routes with less traffic and fewer stops reduce the amount of time your vehicle spends idling, which consumes fuel without moving the vehicle. Utilize navigation apps that provide real-time traffic updates and suggest the most efficient routes.
Explore alternative routes that may be longer in distance but faster in time due to less traffic and fewer stops. Highways and main roads with limited access points often allow for more continuous driving.
