Paul,
Snip............
Try some Mobil One in the "crankcase" typically. It does not break
down
until about 500 F while regular oil starts breaking down at about
250 F. I have been using Mobil One in all my engines for 10 years and
the
Dodge Caravan engine has 200,000 miles while still passing smog tests.
Everything else in the transmission, drive line and chassis has failed
at
least once and sometimes more than once.

Is Mobile One an ashless or low ash oil?  I have always thought so but
have never seen a report?  Two stroke oils are good because they are
ashless; it is the leftover deposits from regular motor oil that clogs
up a wankel; seems like the high pressure additives are particularly
bad.  I wonder if an aircraft low-ash oil would work (but probably WAY
too vicious - I think the Mazda racers like a 20-20).

You got me there Ken. I forgot whether I burned some a couple of years
ago or not. It certainly held up in the oven at 500 F better than anything 
else except turbine oil.
