  • fuel/oil ratio Evinrude 88

    Have a new to me Evinrude 88 that's has been well maintained and low hours. What is a good synthetic oil to premix with and ratio ? The previous owner told me what he did but I mistakenly did not write down his thoughts.

    That motor was designed to run a 50:1 gas oil mix. I have one just like it on a 19 I often put 12 gallons of fuel in after a play day. This is one quart of oil added. 24 gallons of fuel requires 2 quarts of oil...etc...

    I am not sure you will reap any benefits of the higher cost of synthetic oil. It does smoke less but thats about my only positive. It costs more for sure. If you do want the synthetic, penzoil makes a blend that is reasonable. sold at wallmart.

    I run the cheep wallmart TCW3 oil. have for years....

      Thanks Dave,

      Yes I actually was thinking of something like TCW3 not a true synthetic. 50:1 it is then.

        We had a 90hp 'Rude on a Wahoo that we converted to an 88 Special. I ran mostly a Pennzoil TCW3 synthetic blend that they have mostly due to it's low cost.

        You can sometimes find it in the $12/gal range & then I would stock up.

        I am now running an 175hp Etec on the XD100 oil, but still have the gas in the tank with approx. 200:1 mix.
