I'd be surprised if generic motor oil tests weren't all the same price. Lots of cool info in them. They are most valuable when done repeatedly on a vehicle. Then you get nice trends that show if anything is going wrong (eg when bearings start to go you get a little material but it increases exponentially so you know when you can't put off rebuild any longer.)Is the motorcycle oil test $50?
What's the turn around time for results?
