We would have lost WWII without leaded gasoline.  The bombers and
fighters both required 100+ octane gasoline which was only achievable
using massive quantities of tetra-ethyl lead in those days.

While having 100+ octane gasoline made more power possible, if they
hadn't had it, engine manufacturers would still have built very
effective engines.

Not to the same extent, although we DID know about things like alcohols
as octane improvers at the time.

Lead made for MUCH more powerful aircraft engines with much higher
compression, and because the only octane improver we had at the time
was lead there were a lot of crazy volatile engine fuels that were
mostly casing head and lead.  

BUT... the point should be made that if we didn't have ethyl back then,
the Germans and Japanese probably wouldn't have had it either.  Although
the Germans did some some pretty amazing performance features that we
didn't know about (like nitrous), keeping a secret like ethyl would
be difficult.
