Question on mixing non synth VS synth 2 stroke

[95XPinPA]

Just bought a used 95 XP. It's in really good shape. The last owner gave me a gallon jug of the XP Rotax non-synthetic 2 stroke oil. It's has aprox only 1 Qt leftl. I went to the SeaDoo dealer yesterday to get more, and they only had synthetic. Counter guy stated thats what should be used, since around 1993.

Is it OK to mix synthetic with Non?

Should I try and drain/siphon all old non synthetic out and refill with only synthetic?

Thanks.

Ya know if you go to the sea doo shop, and get your information, it is easy to get BAD information.

It seems to me that the shop hands at sea doo shops are responsible for many problems.

Somebody more eloquent than I will chime in.

My say is that you should never mix those oils.
