BRP advertised one of their oils as biodegradable oil. There is now a label that "certifies" an oil as bio oil. Did some reading and stumbled on the Bel-Ray ad. Read the 3rd paragraph and see their description. Bel-Ray does produce great lubricants. https://www.belray.com/bel-ray-marine-lubricantsFor the particular engine platform we are talking about I designed, tested, and have dozens of engines out and running with a simple Re-Circ system that pulls oil out of an engine drain and brings it back up to just behind the carburetor. Normally the drain simply allows the unburned fuel/oil to dump in to the water. This is normally seen as blobs that float to the surface and turn in to a sheen on the water. The re-circ system more completely burns the mixture.
