What motors do you have? I run synthetic and change them every 30 hours. So for those that know me in the last 6 seasons I have done one oil change.

I have a SBC but run it pretty hard (alot of wake boarding). I run conventional oil and change it about 20 hrs. Sent a sample in and they said it was nearly used up. Figure oil is cheap.

Analysis, I use "Oil Analysis Lab" in Spokane, Washington. My last years analysis with 53 hours on the oil was still cleaner and stronger than Merc 25w-40 out of the bottle. I have twin 496hos. The tests cost $15, and take about a week to ten days to get back.

Email them and they will send you free sample and shipping kits with instructions etc.... the reports are really snazzy and very detailed. Cost is about $22
