I got my darn Oil warning alarm back.

OK....so I have recently had some issues with my Oil saddle tank resevior on my Merc 200 EFI. I filled up the saddle resevoir and put the rest in the main oil tank. I started with about 1/2-1/3 of a container. It got rid of the alarm. I have taken the cap off of the saddle oil tank on the engine and lifted the flaot, the alarm quits. PLUS, the tank is half full, and I understand that it MUST BE 100% full....see I am learning...lol

How often does everyone refill their oil per tank of gas. Think, tanks are different per boat.....I am using a 25 gallon tank. Quarts of oil per gallon of gas.
