Biodegradable 2-stroke oil

[Ronbedard57]

Hello all,
i ran with biodegradable 2-stroke oil in my 40hp '62 Johnson this year. Pretty crummy weekend weather, so I couldn't form much of an opinion. I really want this to work, as I'm conscious of the impact I'm having on the air and water. I figure I'm scoring a few points for running an antique motor on an antique aluminum boat rather than buying a new plastic boat with a new motor. "Use it up, wear it out etc."
Anyone care to share thoughts and experience? Is there a variance from recommended mix ratios?
Thanks
Ron

It was my understanding that most, if not all modern two cycle oils are biodegradable.

At least they are far more biodegradable than the old 30 wt dinosaur oil !!

Do you have a link to this oil? I am curious.

Having your engine running right, not too rich, and burning the fuel properly would be most helpful to the environment, regardless of what oil you are using.

If you have to add more of the eco-oil, you might be defeating the intended purpose.

Just because it's labeled as bio degradable doesn't say how LONG it will float around your lake before it breaks down. Even crude oil breaks down eventually, so that's kind of a catch.

Hi,
The motor is always tuned pretty well, and I didn't really see any change in performance when I changed from the Wally-world stuff. Like I said though, the boat wasn't on the water very often this year. She's sleeping now, so I guess I'll learn more next season.
Thanks
