What is the correct oil???

What is the correct oil for my 1994 Sea Doo GTX??? Is it mineral or synthetic?? Years ago my old school Sea Doo mechanic told me only to use mineral based oil. Now I am getting ready to order another gallon and the old product number was corrected by the seller and I noticed that it is for synthetic oil. I know a few years have gone by since 1994 and things sometimes change for the better, but in 2023 what is the best oil for my 1994 GTX?

I found my old original manual and it calls for Sea Doo injection oil 283600004. That number was superseded by 283600118 or 779120. I guess that's good enough for me. I will stick with what the factory calls for.
