Still, it can decrease your car's overall performance, and you may notice adverse effects like poorer gas mileage than usual. However, gas that's over a year old can cause things like engine knocking, sputtering, and clogged injectors.
Heat, oxygen and humidity all have an impact on the condition of stored fuel. In general, pure gas begins to degrade and lose its combustibility as a result of oxidation and evaporation in three to six months, if stored in a sealed and labeled metal or plastic container.
Gasoline breaks down over time, not only becoming less effective as a fuel, but also releasing gums and varnishes into the fuel system. Carburetors in particular are vulnerable to having their small passageways gummed up by these varnishes. And the longer the gasoline sits, the more varnish is created.
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).
How old is too old for gas? However, gas that is more than two month old is generally OK to use with only minor decreases in performance. Gas that is older than a year can cause issues, like engine knocking, sputtering and clogged injectors. Bad gas can be drained from the tank to prevent damage to the engine.
Degradation occurs from the get-go but most gas stays fresh for a month or two without issue. However, gas that is more than two month old is generally OK to use with only minor decreases in performance. Gas that is older than a year can cause issues, like engine knocking, sputtering and clogged injectors.
