Different Climates, Different Gases?

A lot of people (like me) think that when the weather changes dramatically, this means that you have to put a different type of gas (fuel) into your Fuel Tank that we all love filling up so much. WRONG. Whether it’s super hot or freezing cold outside, your car doesn’t need different fuels in it’s Fuel Tank every time the weather changes. The only reason that people change the type of fuel is because different governments usually promote different types of gas for environmental reasons.

Since the weather (especially here in California) can influence the negative effects of things like the exhaust that is released from your vehicle, the different car fuels, and the different blends of gas that there is out there, all this can be used together in order to impact gas-powered vehicles have on the environment. Here in the United States, the oxygenated fuels have the capability of being used in the Winter months and volatility requirements may be imposed in the summer months.

There are some people that have a little bit or trouble comprehending the difference that comes between a summer blend of gas and winter blend - if that’s you then don’t worry; you’re not the only person that doesn’t understand it. The United States Government uses different terms like RVP (Reid Vapor Pressure) and PSI (Pounds per Square Inch) in order to monitor the different properties that gas has. Even though the whole chemistry and terminology of it may be a bit confusing, the whole concept of it is pretty simple - this means you should have no trouble understanding it.

In the United States, the federal government has volatility requirements that impose specific gas blends in the summer that are there in order to cut down on emissions and smog .. and California has enough smog coming from the Fuel Tank of my truck alone. This whole process is done by reducing the amount of gas that is known to evaporate into the atmosphere by taking out some of the chemical properties that are in the gas itself. Typically, the summer blends are only used from the beginning of June until about September; they’re mostly targeted at warm climates. The whole summer blends of gas may essentially be better for the environment, but it can render vehicles nearly inoperable as the combustibility is not as great. This specific reduced level of combustion can eventually make cars hard to start when it’s colder outside.

Different fuels for cars are also made for winter months. In addition to the votality requirements, the government here in the United States has an Oxygenated Fuel Program that mainly focuses on using fuel additives that contain oxygen. The increased amount of oxygen that’s in the gasoline is there to help the gas burn in a cleaner fashion and also reduced the amount of emissions it has. What’s interesting is that the government really only mandates summer blends that are in 12 main metropolitan areas. Because of this, there are some legislatures that have enacted the same mandates statewide - which I think only benefits us in the end. The rulers here in California are the most strict .. but then again, we do have the most drivers.

The main reason why gas is so expensive this summer is because the main switch over periods happen at the beginning of the summer and at the end of the summer.

Do you know what kind of gas your putting in your Fuel Tank this summer?
