I?m currently using gulf western TC-W3 2 stroke oil for my 2006 25hp Tohatsu outboard. It?s half the price of quicksilver 2 stroke oil but is it worth using a cheaper oil? There are so many different oils out there it gets a bit confusing what is the best oil to use for my outboard. What oil do most people use? I bought this motor 1 year ago and am about to give it a service .I've bought a water pump repair kit and a new fuel filter. I will also replace spark plugs and spray some Johnson engine tuner down the carb and let it soak overnight after spraying it into the top of the cylinders. I will also replace gear box oil and that it.Is there anything else I should do Regards Kevin
