Use the Amsoil website they will tell you what oils they recommend

​@@dsprojects8580 seadoo does not recommend synthetic oil in supercharged engine? are you are sponsored by amsoil?

Yes let it warm up for 5 to 10 mins just makes the oil flow better when draining it

That’s why they have a hose hook up buds

@@dsprojects8580 as i said Read the seadoo warning to not run engine out of the water

Okay I don’t know how you are reading that but most have a water hook up to run water like a hose. So you can test ,winterize , maintain your water craft not sure what you are trying to call me out on. Or question you are trying to ask . And as fare as supercharge seadoo go Amsoil has there recommendations on line for oils to use .

So what I am saying with the supercharged seadoo is if they don’t have a oil for it they will not have recommended oil . So what make model motor yeah is your seadoo?

The 10w40 and 10w30 is. The 25w40 is not . I have read that in North America is can not say 100% synthetic on the label if it not do to a law suit that happen

@@dsprojects8580 Correct

@@Q8ANGLER the marine 10w40 and 10W30 are 100% synthetic if Amsoil has a product that is not a 100% synthetic it will show blend on the bottle like the 25w40 marine oil . 100% synthetic means all molecules of oil are the same size even the additives put in the oil giving you the benefits like less heat less ware less friction = better fuel savings . I run the 10w40 100% synthetic in my 350 mercruser boat . And sounds like you have a great maintenance program for your watercrafts . I change are once in the spring but we dont use them a lot so yeah I guess it would pretty much be every 6 months. It really depends on how hard you ride or drive something or even conditions on recommendation for oil change maintenance. But your every 6 months/ 25hour is a great maintenance schedule. And I thank you for the view and comments.👍😁
