  • Oil to gasoline ratio measuring device
    Patent number: 4079629
    Abstract: Various two cycle engines require different gasoline to oil ratios for proper operation of the engine. These ratios may vary as much as from 15 to 1 to 50 to 1 or possible even greater. Usually the gasoline used is contained in one to two one-half gallon cans. This makes it difficult to provide the particular ratio of oil to gasoline in the can. The present measuring device is provided to eliminate this difficulty.
