2007 Sea-Doo RXP 155 NA oil interval

[Bluestream]

I have only 13 hours use since last oil change which was done end of season in Sept 2016. Oil is Castrol 0W40. I would like to go one more year, which should get me to 20-25 hrs. Factory recommendation in 100 hrs and one year.

Any reason not to go 4 years and 25hrs? I dont believe in oil going bad sitting in the crankcase.

Thoughts?

I'm sure that's fine. the argument against it is once the oil gets acidic, it eats the bearings. but you are using a good quality oil. I certainly have stretched the interval on some of our motorsports toys.

Tom, I'm with you. No acid in only 20 hrs use. Also these engines run hot and long, no stop and go in this application. 4 year OCI it is
