The lifespan of gasoline, also known as petrol, depends on several factors, including:
Storage conditions:
-
Temperature: Heat accelerates the breakdown process. Ideally, store gasoline in a cool, dry place below 70°F (21°C) to minimize degradation.
-
Light: Direct sunlight can also degrade gasoline, so it's best to store it in opaque containers or a shaded location.
-
Air exposure: Exposure to air allows for evaporation of lighter components and can lead to the formation of gum deposits that can clog fuel systems.
Gasoline type:
-
Pure gasoline: Generally, pure gasoline has a shelf life of 3 to 6 months when stored properly.
-
Ethanol-blended gasoline: Most gasoline sold today contains ethanol, which attracts moisture and can degrade faster than pure gasoline. The shelf life of ethanol-blended gasoline is typically 1 to 3 months.
-
Fuel stabilizer: Adding a fuel stabilizer to your gasoline can help extend its shelf life by up to 12 months when stored properly. However, always follow the manufacturer's instructions for proper use and dosage.
Here's a summary:
-
Pure gasoline: 3-6 months (properly stored)
-
Ethanol-blended gasoline: 1-3 months (properly stored)
-
With fuel stabilizer: Up to 12 months (properly stored, following manufacturer's instructions)
Important notes:
-
Using old gasoline: Using gasoline that has degraded can lead to several issues, including:
-
Engine problems: It can cause difficulty starting, rough idling, and decreased performance.
-
Corrosion: Degraded gasoline can contribute to corrosion in fuel system components.
-
Safety: It's important to dispose of old gasoline properly at designated hazardous waste collection facilities. Never pour it down drains or onto the ground.
