Sea doo gti 90: what oil?

[lars11]

Need to top up the pwc and no xps to be found nearby.
What’s the consensus on replacement oil for these rotax 900 ace? (No compressor or turbo)
Manual says xps semi synth 5w40. Can’t find what classifications that oil has.
What to look for to find a great oil for this application?

Just use Shell Rotella T6 or M1 0W-40 and be done with it.

2x Full synth over the semi is the way to go. Rotella or M1 and way cheaper than overpriced XPS.

Can find mobil delvac1 5w40. Will it compare to rotella?

I've been using Delo 400 XSP 5w40 in my 2020 Seadoo Spark 90hp.

Any Euro 5w40/0w40 synthetic or HDEO 5w40 synthetic will be as good or better than the Seadoo semi-synthetic blend and about half the price per gallon.
