I am an old grandfather who bought a 95XP 787(in what was thought to be meticulous condition) for the grandkids.  After approx 2 hrs the motor locked up. The previous owner used different oil to save money just before he sold it to me. Had new enjine installed. Don't want to pay $60 for a gal of SeeDoo oil. Have read just about all the threads on oil.  Decided to go with QuickSilver PWC.  Just don't know whether to use 100% synthetic or the blend.  Hopefully I won't open up a can of worms if I ask which would some of you use.  Thanks for any advice.  I just want to make the grandkids happy and get this thing going before summer is over.Thanks again.
