Hi Bart, I formerly?used Aeroshell 100 all the time.? Then my A&P/IA suggested that I switch to Aeroshell?15W50.? He said that it was a much better oil, and he'd rather that I use it in the engine that he rebuilt for me.? I respect his opinion and his experience, so I switched.? Later I heard a talk about aircraft lubricants from a guy in the industry, (not an Aeroshell guy) and he said that the only reason?oil?companies still sell straight weight oils like Aeroshell 100 is because today's pilots think they should use the same oils that their fathers used.? (Funny - that's exactly why I was using Aeroshell 100!)? He said that there is no reason in the world that anyone should use a straight weight?oil in an airplane engine today, regardless of the vintage of the engine.? He had lots of wear data, corossion data and rust data (and pictures) to back up?his claims.? He convinced me.??Actually he recommended full synthetics, but I don't?use that type of oil because?I wouldn't be able to afford to change it every 20 hours.??(Yes, I know?you don't have to change synthetic oil every 20 hours, but all oils?collect dirt, and the oil filter collects junk, and I don't want dirt in the oil, and I want to look in the oil filter every 20 hours regardless.)?
If you change your oil every 20 hours, you should never have a problem with oil quality, regardless of which type or brand you use, as long as it's approved aircraft oil. Just my opinion.?

I have been asked if I want to start using Aeroshell 100 at my next oil change. The airplane is located in Florida and I am told most people here use the Aeroshell. I don't think it is a good idea to switch viscosities, or so I have been told in the past. What is the current thinking on this subject and does anybody have a preference for either engine oil?
