Oil change interval in shop manual?

[shotgun10ga]

My 2011 GTi 130 shop manual says to replace the engine oil & filter once a year or every 100 hours. I feel like that is way too long? I usually just get it replaced after the summer season (50 hours)... am I doing it too early - could I leave that oil in over the winter and continue using it?

Most on this forum recommend changing the oil before winterizing.

I change my oil and plugs every 50 hours. Is it too much? Possibly, but it never hurts to have fresh oil. All it can hurt is my wallet.

Read the part once a year. It is once a year( every season, even if you only put 10 hours on it). If you put 100 hours a season on a ski the you should change it min two times. If you have a supercharged unit you should change it more often. I believe you should change it more often. Clean in clean out. I change my own skis every 15-20 hours, way overkill, but I've seen inside of too many engines that were neglected. I only put around 20 hours on mine, but we only ride one at a time and I have three. Use a high quality synthetic oil like Amsoil. BRP oil is crap. Over maintenance on a seadoo never hurt it, just makes it last longer.

What makes you say that? How do you compare them?
