Winter Fuel Blends

Just read that the fuel production plants are starting to make the switch over to their winter blends. Should hopefully see some reduction in fuel prices too. Be prepared for lower than normal MPG until next April.

☀️ Summer Gasoline
In the warmer months, gasoline has a greater chance of evaporating from your car’s fuel system. This can produce additional smog and increased emissions. Refiners reduce the possibility of gas evaporation in your vehicle during the summer by producing gasoline blends with lower Reid vapor pressure (RVP), or lower volatility. These blends vary from state to state and region to region due to RVP state regulations. They also vary by octane level.
According to NACS, this higher-grade fuel can add up to 15¢/gal to the cost of your fill-up. This excludes the increased cost due to summer fuel demand, which can vary between 5¢-15¢/gal, depending on region. More stringent requirements (like California) can mean even higher prices.

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

Cost for your wallet: Prices typically fall 10¢-30¢/gal starting in mid/late September through late November as gas stations switch to winter gasoline and demand for gasoline falls seasonally as we start staying closer to home. Many retailers continue to sell summer gas until their inventories run out before selling winter gasoline. Hurricane season can also affect prices, ending in a squeeze just before the switch as refiners don’t want excess expensive summer gasoline sitting around especially if refineries are in the path of a major storm.

I buy crap high test. Runs great, actually, you cant drive slow, like it burns differently. I buy good high test. I have a nice relaxing drive. Those guys running that crap high test are trying to put that fire out.lol Winter fuel is complete bull$&it!

 

When you add several hundred pounds of mods, a lift, and larger and heavier tires, you're used to seeing "lower than normal MPG's". Honestly, I've been watching for the winter blend drop the past few years and haven't noticed. Must be negligible

 

Yeah, prices drop a little but mpg drops by a bigger percentage than prices so it costs more to drive the same distance.
