Mixed the wrong oil

[joectran]

I have accidentally mixed my used oil 5W30 from my lawn tractor into the gas tank for my 2 cycle boat motor. The engine is running very rough now. I have dump the rest of the gas tank.<br /><br />Would like any advice on how to clean up the motor or what damages I have done.<br /><br />Thanks

Re: Mixed the wrong oil

How long did you run it that way? Chances are that you just have fouled plugs. Dump the gas and oil, put fresh gas and oil in and change the plugs, probably will be fine. Might have to change the fuel filter also incase some crud got in the old oil.
