Does anyone have any experience using a higher octane fuel to help pass
smog inspections.

Thank you for your anticipated response.

I don't know why it would help. All higher octane means is that the
fuel burns with more difficulty helping to prevent certain problems with
engines designed for it or with carbon build up causing higher than normal
compression.

a brand new air filter in my opinion would be money better spent

No, but I have heard 4 or 5 bottles of dry gas do wonders at test time! It's
the alcohol that cleans up the emissions

Gaaaaaa!

Higher octane fuel is harder to ignite and _may_ send more unburnt
crap out your tailpipe, especially if your plugs or valves are dirty.
Your best bet, and something you should have done anyway is to follow
the service intervals for your sparkplugs, change your air filter, run
a can or two of Techron (or equal) through the system before taking it
in (follow label directions), and getting it up to sustained highway
speeds for at least an hour the day before the test.

A clean, well-maintained engine burning the proper grade of fuel will
need no more than that to pass emissions-inspections. "Proper" is
whatever the owner's manual states is acceptable, even minimally so. A
poorly maintained engine may not pass whatever heroic gestures may be
made prior to the test.
