You can expect an average 55-gallon drum weight to be about 48 pounds (22 kg) for a steel drum, and about 25 pounds (11 kg) for a plastic drum.

If gasoline is poured on free water (unrestricted), the gasoline will float on water because an equal volume of gasoline weighs less than the same volume of water.

Since water and fuel do not mix with each other and because water is denser than fuel, water rests at the bottom of the fuel tank. The prolonged presence of water will cause rust there. The rusting is accelerated if there are ridges and sharp edges in the fuel tank. Rust can also extend to other parts of the fuel line.

Due to the differing densities of water and gas, mixing cannot occur. As soon as you add water to a tank of gasoline, all of the water will settle to the bottom of the tank. The lighter gasoline will float on top. You get the same effect as you would get when you mix oil with water.

What would happen if you put milk in your gas tank? Milk is not flammable. Milk is heavier than gasoline, so it will sink the bottom of the gas tank (now milk tank) get picked up by the fuel pump and sent to the engine. As soon as it get to the injectors the engine will die and not restart.

Take a piece of white notebook paper, and put a drop of the gasoline on it. Then let the gas evaporate. If it is gasoline only (unmixed), then the paper will dry completely. If there is oil mixed in it, you will have an oil spot remaining on the paper after the gasoline has evaporated.

Gas can be very expensive so it’s not ideal to just waste it. Another reason this is a problem is because when gas and oil mix, this causes the oil to lose its ability to lubricate the engine parts. When oil can’t do its job properly, these parts start to create a lot of friction and then the engine could overheat.

Re: How to tell if the gas is mixed with oil? It should be coloured if oil is mixed with it, blue, green or red for most oils. If in doubt, dump it in the truck and start over. Don’t risk cooking the saw.

All readily available two-stroke oils contain marker dyes: blue, green, red (but rarely Gingham). Presumably you have some of your oil left, which will tell you what colour. So… pour some of your mystery fuel into a clear glass.
