Bob,
Not sure what your point here was since this applies just as much to automobile engines as to aircraft engines. In fact I should think automotive engines tend to do far more operations in which the engine does not come up to, and maintain operating temp than do aircraft engines.

Synthetics are not a panacea but they are far from the evil they are portrayed to be. The only real advantages I can think of is, if your oil temp goes over redline unlike regular oils which begin to break down rapidly at over 225 degrees the synthetic does not suffer this same problem. It also does not carbonize around the valve stem a cause of a high percentage of the stuck valves these little engines are famous for.

We all have to make a choice with what makes sense to us and what we have had success with. In the end it's your ass in that aircraft. The FAA in it's infinite wisdom has not done much to improve safety in aviation, if you doubt this then just look at their latest shining example of technology. The new computers for ATC. If you are not aware they are spec'ed out as 486's,,, Now let's see,,, one reason for replacing the old system is a lack of replacement parts, so to fix that part of the problem we'll b ild and install a new system based on obsolete technology. Aren't you glad your life doesn't depend on someone with this mentality,,,,,, or does it?
