What Factors Are Used To Calculate YIELD Figures?

Yield numbers assume the Oil Metering Pump is operational. The ratio used is the Idemitsu recommended ratio of 256:1 or .5 oz per Gallon of fuel. 

Premix ratios for Racing and other highly modified engine configurations are specifically prescribed by the engine builder/tuner. When premixing for an engine WITHOUT the Oil Metering Pump, the generally accepted ratio of 128:1 or 1 oz per Gallon of Fuel is used as REFERENCE ONLY. We strongly urge you to consult all available resources when determining the appropriate premix ratio when not using an Oil Metering Pump.
