Re: Breaking in 40 hp Merc oil injected
Run it on 50.1 premix as well as the oil injection it will give it a double dose of oil.Use this for the first tank of fuel(2 tanks if you are using a small tank,just to be safe) & avoid continuous full throttle running.After the first tank has been used check that the oil level in the oil tank has dropped if it hasnt your oil injection isnt working.
