Re: johnson

Most likely because it is a 2 cycle motor. What year is it and what mixture ratio does it require. You can try synthetic oil and it may oil the water less, but 2 cycle engines do not burn all of the oil since some is needed for lubrication.

Re: johnson

That is not right, but the truth is that it probably is OK. It's supposed to be 24:1, but there was no real change to the powerhead when they went to 50:1 in 1964. Make sure you use only oil Certified TC-W3. Penzoil 100% Synthetic Outboard oil meets that qualification and is bio-degradeable so you can feel better about dumping it in the creek. And your motor was designed to do just that.

Re: johnson

use 24-1 fuel -oil mix. did not change to 50-1 until 1964. the oil slick is normal. be sure you are firing on both cylinders, and carb adjustments are correct.
