Re: Premium vs. Regular gas

[Bill M <y1topbanana73@xxxxxxxxx>]

i may be a little late to the party here but this is my $0.02...You
are not going to see any performance increase unless you advanced the
engine's timing to make use of the increased octane. Just swapping
premium in for regular won't do anything.

The only advantage without a timing adjustment is that most (if not
all) premium does not contain ethanol.
