I found out the other day that Rotax injector oil will mix with water ! I took a plastic bottle that was put in the dish washer I thought I wiped it out dry,but ! I guess not.
When I put the ski-doo oil in the bottle I put the lid on it and rolled it to coat the bottle to get ready to mix Torco SSO oil (to see if they're would be a problem with contamination) anyways as I removed the lid I seen no bubles ? I took a small drop of water and mixed it with the oil, rolled it on a table top and it mixed with the oil - most oils the water is separated from the oil.
I am not saying ski-doo oil is bad, but I never oil mix with water like that.
I was once told years ago - OEM make engines don't they ? and they sell oil don't they - food for thought.
