Always nice to clear the decks beforehand - prevents getting a nasty shock (and a big bill) later on!
Why would one get a shock?
HPMan - that Lyco SL doesn't appear to be new.
Re oil, for a few years I alternated between Aeroshell 15w/50 and Exxon Elite and never saw any correlation between the oil and the oil analysis. I think both are as good as each other, providing perhaps one flies regularly (once a week in my case). What I did find with Elite was that it was more susceptible to creating a brown watery sludge around the dipstick and under the rocker covers. The Shell oil doesn't do that.
