" Hi, I have an older outboard 84ish I think. I was wondering if it is ok to mix different brands of 2 cycle oil? I have 3 or 4 quarts that are Partials in the shop. what is the shelf life of oil if the container has been open? is there any benifate from being consistant in the brand of oil? Is there a paticular brand that you recomend? Thanks in advance for the help!!!

(sounds like a proberb ) "
