The main problem as I see it would be cranking the motor over since...

    Old 2 stroke oil okay to use?

    I have aquired 40 unopened bottles of Nissan 2 cycle outboard motor oil but it is around 15 years old. The oil has been sitting on a shelf in a heated warehouse all these years and I was wondering if it would be safe to use? I can see no visible separation in the oil if that makes a difference.

    Last summer I had a misfire only at low RPM on my 1988 110 Johnson (J110TLCCA) and I determined that the 2 port side cylinders were not firing consistantly. I made this determination by deliberatly running at low speed for several minutes and allowing the misfire to occur, I then killed the...
