Max et al,
A. IMHO, anyone who needs to run 100+ octane fuel in an MG because of run on,
needs to fix his motor not his octane.
B. From what I have read recently, there is more pollution being emitted by
lawn
mowers in this country (USA), than by automobiles; seriously...... I read
that...... honest! Our MG emissions are not too likely to cause any birth
defects
soon.
C. Whatsa tree hugger??????
D. My BMW motorcycle has a catalytic converter. Therefore, I only feel guilty
when I mow the lawn, but not when I ride the Beemer. HeeeHeeee! Convenient isn't
it???
