Just bought a 97 GSX today that only has 28 hours on it. Its always been run on the regular Seadoo injector oil(not XPS). I saw above that synthetic is needed due to the RAVE valves. Why? My GSX seens to run fine so far. My KDX dirt bike has a power valve system that makes RAVE look primitive and I have excellent results running BG oil in it and it's nonsynthetic. I understand the low ash for the rotary valve but not synthetic for the RAVE. Does dino oil gum then up or what.
Thanks
