OIL ANALYSIS for the Apex / Skytrax Gearbox
This is a "Resource Page" and is our recommendation
We do NOT provide this service
I recommend Blackstone Laboratories for oil analysis for both your Aviation Yamaha Apex Engine AND the Skytrax Gearbox. I would encourage everyone to do this so we as a group can start getting some real data for the aviation industry on this combination. Its ONLY $30 / Sample. You can fill out the form on their website and in a few days you get a sample kit in the mail with instructions how to do.
