Re: Mix my own synthetic blend???????
so why can't you, I do it, sea doo first said they required synthetic oil then they said don't use it because it won't stick to the parts if the engine sits for an extended time like regular oil does,, and it wears the parts when the engine is started for the first time after sitting for a week or longer.. I believe the synthetic oil was for the e p a readings and not because it works better than regular oil. I know it had that purpose with the 2 stroke engines..
