Gasoline is a vital part of your vehicle, but it can also be dangerous. If you don’t know how to dispose of old gas, you could be putting people at risk and possibly hurt the environment or animals.
In this handy guide, we discuss how to dispose of old gas cans and the fluid that might be left inside.
How To Determine If Your Gas Is Too Old (Dangers Discussed)
You might be asking yourself, “How long can gas sit in a car before it goes bad” or “Is 2 year old gasoline still good?” Oxidized fuel is going to be darker than fresh gas. It might also have a sour smell. Pour some of the gas into a clear container and compare it with fresh fuel.
There’s no hard date on when gas will go bad. Part of this is because you don’t know how long the fuel sat at the pump or how long it took to get from the refinery to the station. However, it’s often recommended not to leave gas to sit in the tank for more than a few months.
Using old gas poses the following risks:
As gas becomes old, some of the chemicals begin to evaporate, leaving you with a heavier fuel. This gas will be harder to ignite, leaving you with engine performance issues.
Gas reacts with air, causing oxidation to occur. When this happens, the chemical composition of the gas might change, causing damage to your engine.
Temperature changes lead to condensation, which leads to rust contamination of the lines or tank. You could look at a costly repair if you leave condensation in the fuel system.
