Does gas go bad if it sits too long?
Bad fuel will have a darker or muddier appearance. Bad fuel, especially gas containing Ethanol, can also draw in water vapor which can corrode the tank and fuel system. If left for a long period of time, the damage can be costly to repair.
What happens when gas sits for years?
What happens when gas sits around inside a car that’s been parked for a year? 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.
What happens to gas when it sits for too long?
Gasoline is incredibly volatile, which means that it separates and vaporizes when it sits for too long. When gas separates and vaporizes, it becomes much less combustible. As a result, engines using old gas are significantly less efficient, which can cause problems for them that we’ll discuss in a bit.
Why does gas go bad in the summer?
Unlike the crude oil, gasoline has certain chemical-specific characteristics with highly refined products. Using the wrong seasonal blend affects the volatility of characteristics of the gas. Thus, in the summer, gas doesn’t evaporate easily while in the winters it does.
Is it possible for gas to go bad in a car?
Most drivers don’t have reason to worry about how long gasoline has been in their car, because it doesn’t sit for very long. But gas can go bad. Maybe you have a car that you never drive — it sits for months at a time.
How old does gas have to be before it goes bad?
For one, it’s hard to know how old the gas you just bought actually is. It may be fresh from the refinery, or it may be a month old already by the time you top off your tank. Some gasoline is mixed with better (or more) oxidation inhibitors than others.
How long can gas sit in a car before it goes bad?
It is possible the gas in your tank could be over a month old when it was pumped. If you are in the market for a new car we can help you find local deals and the latest incentives from dealers in your area. When gasoline gets old, its chemical properties change.

What happens if you leave gasoline in the tank for too long?
If gasoline sits for too long, either at a gas station or in your gas tank, so many of these compounds can evaporate away that the octane rating of the gas drops to a point where it won’t burn efficiently in your engine. If left alone for months and months, the gas can eventually turn liquid gasoline into a thick, varnish-like material.
How can you tell when gas has gone bad?
One way is to eyeball it. Oxidized fuel often turns darker over time and may even smell sour. You can check stored gasoline by pouring some into a clear glass container and comparing it side-by-side with known fresh gasoline. If your old sample looks noticeably darker than the fresh gas, you have strong evidence the gas has gone bad.
