How you mix oil and gas?

I have a scooter bike and it says mix 20:1 of gas and oil, what does that mean?

If its a 2 cycle motor use two cycle motor oil. You buy the oil at Wal-mart or auto store. On each bottle they give you the amount of oil you are to use from the bottle per gallon of gas. There is a little measuring area so you can pour in the correct amount. If I were you, I would pre mix the oil and gas in a separate container first. If you don't use it all, you can fill up the motor cycle when you get back from tooling around.

20:1 in volumn. That is, take 20 gallon gas, 1 gallon oil. Or 20 ml gas, 1 ml oil. Whatever unit you use, keep the volumn ratio to be 20:1.

You fill a 1 gallon gas can with gasoline and then buy a smaller container of oil. 1 gallon of gas is 128 fluid ounces, so 1/20 is about 6.4 fluid ounces of oil. Dump 6 to 7 fluid ounces of oil into the gasoline container. Shake or stir, gently! and you have your mixture to put into the scooter.

it is a ratio of oil and gas mixed.
you should mix 1 1/2 or 2 oz. of oil to a gallon of gas and pour into scooter. it is like mixing it for weedeaters.

20 gallons of gas requires 128 fluid cunces of oil

one gallon (1) = 128 fluid ounces

20 : 1 means for every 20 gallons gas a mixture
oil must equal 128 ounces

20:1 ratio is indeed 6.4 ounces of (air cooled 2 cycle engine certified now!!!) oil.... per one gallon of gas. Just pour the oil in the gas, give it a little shake and dump it in the gastank. Failure to use oil (not just any oil, has to be a 2 stroke air cooled certified oil) will seize the engine..... in other words you'll be buying either a new scooter or replacement engine..... if its not worth rebuilding.
