I haven't been flying in a few weeks due to the weather. It has been a rather wet April and the alignment of rain showers with the weekend has been exquisite. I have nineteen hours on the engine so far. The plan is to run it to 25 hours, then do the first oil change. At that point we'll most likely switch to regular oil. I do have Camguard that I intend to use but my understanding is that, with a new or overhauled engine, you should run at least one oil change interval on regular oil without Camguard before starting to use it. If the weather is nice at some point during this next week, I may just take a half day off from work and go flying, then make up the time later.
