Kelly asked which oil?

I use Mobil One synthetic 20-50W.  I found that they now offer a motorcycle version,
which has anti-foam additives.   I could not see any difference from their normal
engine oil as to foaming.  I have since replaced my clear vinyl tubing with
high temp oil hose, so cannot view the oil.  Note: I never flew with the clear stuff,
just ground running without the prop.
