Question

HOW DO I PUT MOTOR OIL IN A JOHNSON 20HP MOTOR?

Answer 1

depends:  what year is your motor?

need to know whether you have VRO/OMS or premix motor.

Answer 2

You have a 2 cycle engine. Prior to 1964 it takes 24:1 oil / gas ratio. 1964 and later takes 50:1 oil / gas ratio. Use a good grade of TCW 3 grade two cycle oil and follow the gas to oil mixing ratio.

Answer 3

Isn't that a 2 cycle engine? If it is (most are) then there is no crankcase sump to hold oil. Oil is mixed with the gas before pouring it into its fuel tank and is burned up as the engine runs. Usually the gas / oil mixture is 40 to 1 or maybe 50 to 1. Two cycle oil must be used.
