How To Fix Old Stale Gas

When gasoline is stored for long periods of time, it can become difficult to start an engine. The gas can oxidize and form gums that plug fuel filters, carburetors, and fuel injectors. The ethanol in gasoline can absorb water, causing phase separation, which can make starting the engine almost impossible. A third problem is evaporation. The most volatile hydrocarbons in gas can evaporate, and as they are necessary to easily ignite the fuel, it can become very difficult to start your engine.
In this video, I demonstrate how a volume of gas that had been stored in a vented lawn mower all summer loses these highly volatile hydrocarbons, as compared to the same volume of gas that had been stored in a sealed gas can and protected from evaporation.
In this experiment, the gas that had been stored in the lawn mower had already lost the highly volatile hydrocarbons, or "light ends", through evaporation over a hot Los Angeles summer. The gas that had been stored in the gas can still had these light ends, and once exposed to the air, evaporates at a faster pace.

This is done awesome! Keep up the good work

always trust an old guy with a pink floyd shirt. Not only does he have a good taste in music. He is so old he was there to see the first oil well get tapped. xD

Gasoline wasn't used in IC engines until 160 years after oil.

Stay away from any petrol with ethanol for outdoor power equipment especially if your not using it for long periods. The ethanol degrades rubber fuel lines and seals and can cause thick viscous particle bonds in the fuel that can easily cause blockages in the small components of carburettors. In Australia the top octane rated petrol is 98 use the US equivalent of this it lasts longer when stored and has been found to have very little impurities and very real internal cleaning properties.
Side note: not related but if possible always use mineral based oil for 2 strokes preferably premium mineral, and add small amount more then asked by manufacturer specifications (eg if 50:1 ratio is called for put 40:1 ratio ) too much isn’t good and can cause carbon build up in all areas of the 2 stroke engine but small amount extra overall (especially in break-in period) can extend the life of the equipment exponentially 😉

Lol I’d have finished my nachos before even trying to start the mower

So, what brand of fuel additive did you use?

StarTron, of course!
