I had to remove the oil pump on my Mercury due to malfunction. On my first tank I accidently double oiled when adding my oil. emoBang
What do I need to do other than drain the tank? Any suggestions would be greatly appreciated.
It will run with double oil. It will just smoke more than usual. Just go fishing. Run about a 1/4 of the tank out and fill back up with gas. Then just add oil when you add gas. I would not worry about having too much oil. Not enough oil is a bigger problem. JMHO
I have a 225 efi. I thought I had a problem with the oiler so I added oil to the gas. It ended up fouling 2 plugs and ran like crap. I would drain at least half the tank if not all.
Run it. If it fowls a plug or 2 it's not a big deal. But most in likely it will not. Like the other guy said. Run about a 1/4 of it out refill tank. Then after that go back to normal. Besides when was last time you changed the plugs if it has been awhile I would change after next couple trips anyway.
1 time will not hurt it but don't make a habit of it. The additional oil can accelerate the carbon build up and cause the rings to seize in the ring lands causing excessive cylinder leakage. On 2 strokes they have locator pins that prevent the rings from rotating to prevent the end gap catching a port. In a 4 stroke the rings actually rotate keeping some of this carbon worn off. Here is an example of what this does as this was an engine that had 70% leakage due to the top ring was completely coked and was seize.</p>
