A four cycle engine does not use a gas/oil mixture. The oil is in the crankcase and the gas goes in the gas tank. If you put oil in the gas on a 4 cycle engine it will run poorly and smoke a lot.
Any quality 2 cycle engine oil
2 cycle need to have oil mixed in the fuel to lubricate the engine. divide 128 by the mix ratio and that will give you the amount of oil to mix in one gallon of gas
It simply means that the 2 cycle engine requires a 40:1 ratio of gas to 2 cycle oil. This translates to 3.2 oz of oil per gallon of gas.
Oil is put into the gas of a 2-cycle engine as coolant, as it does not have a reservoir of it's own oil. The oil to gas ratio is the ratio of oil to put in a certain amount of gas. A common mix is 50:1, meaning 50 parts gas to 1 part oil. Note: Only ever put oil in the gas of a 2-cycle engine, which will usually have the gas cap labeled with an oil can, and will sometime be labeled with the mixture ratio. 4-cycle engines will not run on an oil/gas mixture and will simply foul the spark plug and cause extra carbon buildup on the combustion chamber sides.
2 cycle engine are mixed 40 to 1 ratio. One Gal. of gas to 3.2 oz of oil.
Its a 4 cycle engine.......gasoline only
Look on the oil container and the engine that you want to use it in. The engine will tell you what ratio to mix the oil and gas at. The container of oil will tell you what amount of gas should be mixed with it. I have found that the best way is to put the oil into an approved gas can and then add the gas to it. This helps to mix the oil better.
A gas only engine has a spout where oil is added to the engine. If there is no spout, then it is a gas/oil engine. FYI - gas only engine is a four-stroke (four-cycle) engine and the gas/oil engine is two-stroke (two-cycle).
2 cycle engine are mixed 40 to 1 ratio. One Gal. of gas to 3.2 oz of oil.
A 2-cycle engine requires a fuel/oil mixture. The ratio of oil to gasoline depends on the manufacturer's specifications for your particular engine.
The 4 hp Mercury requires a 50:1 ratio, roughly one pint of 2 cycle oil, to six gallons of fuel.
The 50 hp Force outboard requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
