IMHO, synthetic oil is probably the best thing you could do for your engine. HOWEVER- To take advantage of its longevity, have a sample analyzed every 2 or 3,000 miles, so you will know when to change it. I would STILL change the filter(s) at the prescribed intervals just to play it safe. If you follow a plan like this your engine will be happier than you are while doing your low-level flying!
