Before operation, gasoline must be mixed with a good quality synthetic 2-cycle air-cooled engine oil designed to be mixed at a ratio of 40:1.
Most STIHL gasoline-powered equipment runs on a 50:1 mixture of gasoline and 2-cycle engine oil.
A: Mix 3.2 ounces of Poulan 2-cycle air cooled engine oil to one gallon of fresh unleaded gasoline to obtain the recommended 40:1 fuel to oil ratio. Over a period of time oil will separate from gasoline.
The fuel ratio is defined by the following equation: (1.1)Fuel ratio=Fixed carbon (%)/Volatile matter (%).
To calculate the oil to gas ratio, divide the oil volume by the gas volume.
Per the American Society of Mechanical Engineers (ASME), the specific ratio – the ratio of the discharge pressure over the suction pressure – is used for defining fans, blowers and compressors. Fans have a specific ratio of up to 1.11, blowers from 1.11 to 1.20 and compressors have more than 1.20.
Common gasoline and oil mix ratios are 50:1 and 40:1. Meaning there is 50/40 parts gasoline to one part oil when mixed. The lower the mix ratio number the more oil per volume in the gasoline. To mix properly add oil to your gas can, then add fresh gasoline from the pump.
Gas turbine engines typically operate at air–fuel ratios of 60 : 1 or more. Combustion, however, takes place as a swirl-stabilized diffusion flame.
