Re: TCW3 Oil and Non Outboard Applications
Here's info straight out of an air cooled Sears Gamefisher owner's handbook. The powerhead is a box stock 7.5 hp Tecumseh 2 stoke lawnmower engine. <br /><br />Use 50:1 BIA TCW oil @ 1/6 pint for each gallon. If any other than BIA TCW oil is used (never use multigrade), a 32:1 ratio must be mixed @ 1/4 pint for each gallon.<br /><br />Most of us know that Tecumseh motors aren't exactly the best out there but they have been making them long enough to what oil does to their motors. I guess this shows that all air cooled motors are not created equal and blanket statements about oil use should be taken with a grain o salt.<br /><br />Like JB suggests, following the mfgs owner's manual is the best insurance you have for picking the right oil. There is no way to second guess the mfgs on what oil you should use in their product. Reading sales hype that contradicts the motor mfg doesn't cut it and is normally generated by salemen who know jack squat on anything but how to sell. Unless you really "know it all", going against mfgs spec is just asking for problems.<br /><br />About mixing oil in your 4 stroke gas. The Snapper lawnmower company used to DOUBLE their engine warranty if you mixed oil in their 4 stroke Briggs & Stratten engines. I don't know if that is still a policy but it was in writing and was for real. It sure doesn't appear they were worried about it.
