How fast does gas go bad




















Many drivers are always on the lookout for ways to cut their spending at the gas pump. They may choose to buy the most fuel-efficient vehicle , such as a Honda Insight or Toyota Prius. Trucks and large SUVs usually use more gas than smaller cars. For some drivers, it makes sense to limit their daily driving as a method of saving money. Different types of fuel have different lifespans. For conventional gasoline, it usually lasts anywhere from three to five months in your gas tank. Diesel fuel can last twice as long, around six to twelve months.

Gasoline should be kept in an airtight container. You should always label when the gas was purchased and stored. Keep gas in a cool, low-oxygen environment. If your stored gas becomes exposed to high heat and humidity, it can increase the volatility and potential for fire and explosion. For this reason, having a container with more than five gallons of fuel is not recommended. When in question, check the color of the gas compared to fresh fuel.

As gasoline ages, it tends to darken in color. Contact the experts at Hy-per Lube for additional insight into how long gas lasts, and use our store locator to find the store nearest you with our line of high-end, stress-tested lubricants, coolant treatments and fuel system cleaners.

Does Gasoline Expire? If so, you might be thinking about your gas and wondering if it has a shelf life. Long story short: yes, gasoline really can go bad.

However, there is no hard and fast rule as to when it will expire. Generally, properly stored gas can last between 3 to 6 months; if you add fuel stabilizers, you can extend its shelf life by a year or so under optimal conditions, of course. We know what you might be thinking — if crude oil can last for millennia, why does gasoline have such a short shelf life?

Gasoline is made up of a complex cocktail of carbon and hydrogen atoms, which bond together to create combustive hydrocarbons that make engines run. The end product is an amalgamation of various compounds that work together to help power your vehicle of choice. This is thanks mostly to three big environmental factors: oxidation, water, and evaporation.

You might recall that we mentioned oxygen as one of the main ingredients in combustion — but it also causes oxidation.
