My 02' S2K just hit 90k miles.. time to change oil (I do it every 3k miles)

Question is... should i keep using the same one as the manual says??? (10w-30)

or use a different one?

I use Valvoline.. any better oil ??

 

Sounds like it is working fine for you. I wouldnt hesitate using their high mileage oil. - maxlife 10-30 , it has a good record and can help clean things up and might do a bit extra seal conditioning for your engine which can't hurt. Even if you use it for a couple runs a year it could help.

 

any oil will be fine at that OCI. I would continue using cheap conventional.
