Oil Change, what are you using

[astravierso]

I use Phillips XC 20/50 with no complaints. No other additives. Oil sampled at each drain. Wear metals within "normal" range. Filter strap for oil filter changes, this and a light coat of oil on the filter O-ring and never had an issue.

I use the Tempest filter and the Tempest torque wrench sold at aircraftspruce.com to torque it.

And don’t forget to cut that filter open after removing it. Aircraft Spruce also sells the cutters.

Shell 15-50W, camguard and Tempest filter every 25-30 hours

For those interested in doing something more than just cutting open your filter and looking at it on the bench there are labs out there who will process you filter and provide you with data which you can trend to monitor the health of your engine. I have done this on large mining equipment for years with great results and I am starting to do this with my "B". Below is a link to the lab I use (and no I don't get anything for putting this out here). There are other labs out there who do this as well but I cannot speak to the quality of their work. As a side note the owner of the lab and one of the Sr. Analyst's are pilots.

If you are interested in how to do a filter cut, field flush and field analysis using a gram scale and a USB microscope to analyze what is in the filter (ferrous, non-ferrous and particle size and count) let me know. This is a gross test but can still yield some usable data if done consistently.
