Like John, I broke in with Dino Oil, but then I filled it with Royal Purple
50. (pretty bottle...good basis for my choice, huh...Ok, I hear good
things about it too)
I
think Mazdatrix recommends against
synthetic, however, I believe there reason is that the synthetic does not
burn, or burn well, when being used to lube the apex seal when using oil
injection from the oil pan. However, in most aviation uses, we are
adding two stroke oil to the fuel, thus not an issue for us. So, it may be a
nice improvement to run the "better" synthetic stuff.
Also, IIRC, the conventional wisdom is to run the
cheapest 2 stroke oil in the fuel since it is enough to do the job and it is
just burning off anyway. I have heard of good prices by the gallon at
Wall-Mart (of course I never think of it until I need it and the buy whatever
is convenient at the parts store....)

All,
What is
everyone using for oil in their 13Bs? It appears that the
shop manual specifies 10W30 or 5W30 (for cold weather).
Are people flying regular motor oil or are you all flying aviation
oil (aeroshell, or equivalent)?
