Hi all.
I had changed the oil in the process of starting the annual condition inspection. Not really started the inspection yet but wanted to get it done anyway. I flew with the new oil for an hour and half. I started the condition inspection and my number two cylinder which has always had lower compression than the other three was reading only 30/80! I obtained another cylinder which had been overhauled and swapped them out. In the process of doing everything by the book, I replaced the barley used oil with mineral oil for the break in. All is well again in the compression department. The mineral oil needs to be run about 25 hours before going back to my usual aeroshell w100.
Here's the question. I drained the oil in a clean bucket. It's currently sitting inside my house covered. Can I put this oil back in when I drain the mineral oil? With a case costing $59 plus shipping... well you see why I'm asking?
Thanks for your thoughts.
