Oil for a 04 VES 800 ?????????

Rprecision,
I've been using every oil under the sun from mineral to synthetic in all my rigs and have varying success/failures/opinions on all of them. I did like the "inside" information that indydan gave based on hundreds of cranks he's seen, and I am going to switch to a cheap mineral based oil on my 2008 rig. I think the possible extra exhaust valve cleaning is worth the risk . I do agree with indy that modern synthetics are hell on seals and internal gaskets etc., and that alone is reason enough for me. my .02

You found a gem of a thread. I personally would do exactly what Indy Dan reccommends. I run Polaris Blue but may change if I find something cheaper that I like.

Just my $.02
