The previous owner was running normal 2 stroke oil premix'd for about 5 hours or so prior to selling me his ski. He was mixing it a bit rich he "claims" to break it in.
I'm just going to use the XPS synth since thats what I use in the other seadoo.
My question is, should I run the ski out of gas before filling the tank with premix'd XPS? Or is it ok to just top it up now with synth and have it mix with whats in there (about a half tank of normal shell 2stroke oil).
I don't wanna mix them if its going to change the oil properties in a negative way...
