    Sea Foam/ Fuel grade

    I have a 70 HP 1992 Evinrude. I burn midgrade gas. Is this preferred over the lower octane fuel? Also,I add a can of Sea Foam often. Does this help the motor?


    If you hear banjos upstream,turn and paddle in the opposite direction.

    I would use regular fuel, add seafoam to fuel as you say and Decarb once or twice a year, depending on use. Then enjoy yourself.

    Yes, anything but 87 is a waist and you may even be adding more carbon with the midgrade. Contrary to popular beleif, regular burns hotter than supreme.

    And engine that is designed to run on 87 will perform no better and maybe slightly worse with supreme. It may however sound smoother do to the slower burn rate.

    If it's suppose to have regular, burn regular.

    I love SeaFoam, I put it on my cerial in the morning and gargle with it when I brush my teeth.



    There is a fine line between \"FISHING\" and just standing in the boat going through the motions!!!

    Use the regular gas, and decarb once a year or every 100hours.
