Generally speaking, petrol has a shelf-life of six months if stored in a sealed container at 20 degrees – or just three months if kept at 30 degrees. The more it's exposed to heat, the more quickly it will go off. If the container isn't sealed, you'll be able to keep it for even less time.
.
Also know, does petrol go off over time?
Petrol will generally last for around 3 weeks at summer temperature in a vented fuel tank, after which time the performance will suffer, and it will be best to add fresh fuel to restore the performance. Petrol in a sealed container will last for more than 6 months before the performance suffers too much.
Beside above, does old fuel damage engine? The less volatile the fuel, the less effectively it burns in your engine. The result is diminished engine performance. Your engine may still start and run, but it probably won't run as well. The good news: Once the old gas has been consumed and the tank is topped off with fresh fuel, the problem should cure itself.
In this way, what happens to petrol when it gets old?
If the gasoline is old and stale, it will have lost a portion of its volatility. The lighter components of the gasoline (remember, gasoline is a mixture of different hydrocarbons) have probably evaporated off or disappeared. This causes the remaining gasoline to be less volatile and less able to burn as needed.

Never put or keep petrol in unsuitable containers. Some plastic containers will dissolve when petrol is put in them. Always use secure metal or approved plastic containers which are properly marked.What does bad fuel smell like?
Gas contains volatile compounds that allow it to burn. As these compounds evaporate, gas becomes less combustible and eventually turns into a gummy varnish-like substance. When this happens, gasoline no longer smells like gasoline; it smells like pungent varnish. Step 2: Look for discoloration or particles in the gas.Can old gas cause a misfire?
Consequently, bad gas is good for the repair business. When people use gasoline that does not keep their fuel system clean, their injectors gradually clog up with varnish deposits. This results in a lean fuel mixture that may cause the engine to misfire, idle poorly, and hesitate or even stall when accelerating.What does stale petrol smell like?
If the smell is sour or is similar to varnish or nail polish, then you're most likely dealing with stale fuel. Dip your finger into the open gas tank to see if the fuel is cool or warm. If it's noticeably warm, then it's most likely stale.How do you test the quality of petrol?
Method 1: Filter Paper Test. Take the filter paper and put 2-3 drops of petrol over it. If the petrol evaporates within little time leaving no stain or mark on the filter paper, it means petrol is pure and of good quality. If it leaves any stain or mark on the filter paper, then petrol is not pure and of bad quality.Will seafoam help old gas?

Volatile fuels such as petrol and two stroke mixes will store for up to one year in a sealed container. After that period the fuel may still be fit for purpose but problems such as hard starting and spark plug fouling may occur due to lack of light components.Does gasoline evaporate completely?
Gasoline tends to evaporate quickly on the surface of the water compared to heavier oils, although not all of this very toxic chemical evaporates. Gasoline, even in small amounts, can adversely affect fish and plants that live there. Gasoline vapors may be toxic to birds and mammals at high concentrations.How can you tell if gas is ethanol free?
To determine if ethanol is in the gas:- On a test tube or olive bottle six or seven inches long, make a permanent line about two inches from the bottom.
- Fill with water to this line, then fill the tube to the top with gasoline.
- Cover the tube, agitate it, and let it stand.
