4 stroke outboards......Actual for that matter, does it really matter what oil is used when a person changes oil?????


I have both.......60/40 Mercury, 2 stoke and 8 HP Yamaha 4 stoke........

Walmart has the best price I can find, in a retail store........for the 2 stroke...



It does matter for the e-tec. According to every mechanic I've talked to when I had my e-tec. The variable oil injection system is pretty incredible. You use so little oil in an e-tec it has to be tuned precise I would imagine. Evinrude doesn't even recommend their "normal 2-stroke" oil in a pinch.
