Good morning to all, I know there has been several posts inregards to oils for seadoo,s. I have just aquired a 96 gtx and 01 gti. Not sure what previous owner was using for oils so I wanted to get some opitions on what to do. I have full syn. oil in stock but was hesitant to full tanks not knowing if oil that was in skis was a syn. blend or full syn. Whats the thoughs on mixing them and is that really a problem?
