Haven't some of the European countries banned ULP because it is
carcinogenic???

Oh yeah I forgot that part, the fuems from running ULP without a cat
conv are supposedly carinagenic, thats why you should use LP in lawn
mowers ...
Is there any truth in that?

I've always been fairly doubtful about the environmental responsibility
line
with ULP. When you consider all the crap they add to it to make up for
the
lack of lead is it really any less polluting? Some of the aromatics
(*thinks back to organic chemistry*) are supposed to be carcinagenic
aren't
they? I think it's all a load of garbage personally!
