i just got a new Coleman 2.6 outboard. Put oil in for first time to run it for break-in. grabbed wrong bottle. Engine takes 20 oz. I put in 10 oz of 25W-40 before i realized. put the other 10 oz of 5W-20. Can i run it for the 1 hour of breakin with this combo or should i drain before i start and put in the recommended 10-30?
 
Drain all the oil out and refill it with the correct oil.......don't try to save the incorrect oil; just chalk it up to "stupid tax".........a factor in boating we are all quite familiar with.
