As someone who has been boating for quite a long time, I’ve had the time to develop preferences for certain brands. When you’ve been participating in any activity that requires you to purchase products, you generally will get a feel for the brands that can be trusted and the ones that you won’t purchase products from.
In my experience boating, Evinrude Johnson has made a lot of quality products. Since I have an engine made by Evinrude Johnson, I have stuck with Evinrude Johnson 2 stroke outboard oil and that decision has been working out quite well for me. I plan to continue using products made by that brand.
