However, I am a FIRM believer in using the brand of oil which is the same as your motor. Example: Evinrude = Evinrude Oil Mercury = Mercury Oil Yamaha = Yamaha Oil etc., etc., etc............

Marine 2-stroke oil should say on it "TC -W2" 2-stroke outboard oil, this means that it is rated for "2-stroke water cooled engines", this type of oil may be used in outboards, AND lawn equipt. AND air cooled engines. There is another type of 2-stroke oil made specifically for air-cooled engines (usually green in color), it can be used on any"AIR COOLED" two cycle engine EXCEPT "WATER COOLED" OUTBOARDS, so look for "NMMA" or "BIA" certified on the bottle of oil that you are about to purchase, also look for "T-WC" (Two Cycle Water Cooled), remember that measurements differ with different brands of oil, "West Marine" oil is 3.4 oz of oil added to ea. gallon of gas, as where the manufacturer's brand may only require 2.8 oz of oil adder per gallon of fuel, so what looks like a bargain, may not be a bargain, as the concentration differs. mw

I would use "Carbon Guard" with it though, Yammy users should add "Ring Free" every time they top off the tank. This prevents carbon build up (the number 1 killer of outboards), and hot spots on the pistons, and cylinders, remember that today's fuel quality is the worst it's EVER been in the industry. mw

I use Evinrude oil for the Johnson 115 as well as the Evinrude kicker. With that said, I am guilty on occasion of showing up to the pump and having to use a “generic” brand.

He told me basically what Joe said, stick to the manufacturers oil and to use no-name was asking for trouble. Never used anything else since.
