Re: merc outboard
If you are as cheap, Oooops, I mean, as cost effective as I am, then save the oil in a separate container and use it to mix for weed-wacker fuel.
But like I previously posted, it WILL toast your motor, not IF, but when. When that gear oil restricts the flow of TCW-3 you WILL lose that nice $$$$ motor.
Always remember that old adage.
Pay a bit NOW, or pay a whole LOT later.
Which can you afford?
It isn't even worth thinking about, is it?
Just change it and be done.
And I bet you will NEVER make this mistake again, so actually, it is a cheap, errr, I mean, a much more cost effective lesson than a whole motor.
