Good ol' archives! I'm getting ready to change the oil on my A75 and started doingsome research since I'm now up in Oregon rather than down in Texas and Iwas concerned about what viscosity and type to use up here. Cut to the chase,I settled on Aeroshell W100, straight 50 weight, but I hit the archives and searchedon 'Aeroshell' because I knew I had asked the question about oil for Continentalswhen I first got the airplane. From January 2006, from Jack Phillips:>I ran straight mineral oil (SAE 50 wt) in mine for the first 25 hours>for break-in. Since then I've been running Aeroshell Oil W 100,>Ashless Dispersant (which is also what I've run in every plane>I've ever owned, including a J-3 with an A65 Continental).Thanks again, Jack! Anyway, what I learned from my research was that we don'tneed to spend money on synthetics in the small Continentals... the benefits ofthe synthetics are that they hold up better under high temperatures (which wedon't run) and they retain their properties for much longer (which we don't needsince we change our oil frequently in these engines that have no oil filter).And we don't need multi-viscosity oils because it seems that they don't clingto the metal parts as long as straight-grade oils, which is important ifthe engine sits any length of time, which aircraft tend to do.Seeing as how Chief Aircraft is right in my backyard, I stopped in and picked upa case of W100... and some new spools of .041 and .032 safety wire, too ;o)--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Piet airfoils
