Actually, Jim. Tracy Crook is getting well over 100 hours before SAG with
unleaded gas, so its a bit better than twice the Leaded life I have been
experiencing. The only difference being the absence of Lead in his MOGAS.
Perhaps the heavier lead is harder to blow off the ceramic cone than just
the carbon {:>)

That makes sense. Guess I misunderstood that 100LL cuts life of the
plugs in half and that twice the "leaded" life of 25 - 30 hrs could be
expected from unleaded gas. That's still only 50-60 hrs. You have to
change plugs every oil change?
I've never heard this happening anywhere else ... Jim S.
