Hey everyone,
This is something that is bothering me.
Besides my 170 CC, I own another boat, it's older (27 years) 14 aluminum job and it has a older (27 year) 35 hp Evinrude motor on it.
I just got it back from the mechanic, and among other things he told me I was running my gas/oil mixture to rich, okay, and that I should only use Evinrude 2 cycle oil for my mixture- huh???
He said if I didn't, I would keep fouling plugs, and lose performance.
I did some research on this and I did learn that there is a difference between TCW-II and TCW-III oils, with big variations in the different brands of TCW-II oil, but not so much with the TCW-III oils, except for price. An Evinrude 2 cycle oil is +/- $30.00/gallon other brands are $12-20/gallon.
Why I am confused is, this engine was built before there were differnet types of 2 cycle oils, and it has seem to run fine for all the years I have own it, why the big change in things now?? Is it because the blends in gasoline are different now then they were then? Is there something in Evinrude's 2 cycle oil that makes up for these differences?
I'd like some input on this before we head for northern Canada to go fishing next week.
Help me out here folks.
Thanks
Kevin
