    24:1 is correct ratio for that year of engine. Use TC-W3 oil.

      So explain this to me in gallons - if I use 1.5 gallons of gas, how much oil should I use

        1.5 gallons is 48oz. At 24:1 you add 2 oz of oil.

          Some will run 24:1, but I actually prefere 16:1 in motors up to 10hp. 24:1 in 15hp or bigger. Many here run 24:1 without issues though.

            I'm with Zeph, I go at 16:1. For my figurin' I divide oz by the ratio I am using and that tells me how many oz to use (128/16=8)(128/24=5.3) etc.

              Uh-oh, recalculating..... 1.5 gallons is 192 oz. so about 8 oz of oil is needed - 1 cup

                Agreed 8 ounces of oil for 1.5 gallons of gas for 24:1. If you want to run 16:1 you need to mix 12 ounces of oil to 1.5 gallons of gas.

                  To be very honest, the decals on that motor will say 16:1 (1/2 pint per gallon.) These motor are 100% friction and no needles at all. Oil is the cheapest thing you'll ever put in a motor. Why skimp on it?

                  It sucks that nymarine watermarked all their photos.

                      The motor says 1/3 pint for every gallon. If I go by that, I am at 8 ounces (7.95) per 1.5 gallons of gas. Thanks for all your help guys! I really appreciate it!!!!!!!!!!!!!

                        for a 1969 Evinrude Lightwin 4Hp would the correct fuel:oil Ratio be 50:1?

                          Yes that's the official line. 1964 and newer use 50:1.
                          However these mall motors do not have needle bearings throughout so if heavily used are better run with a bit more oil.

                            One day you people will discover litres and cc like the rest of the world use.......... Doesn't half make calculating fuel mixtures easy!

                              going to liters and CC's is like a new pair of boots.... you curse for a while but eventually they fit around your feet and in your head
