100 Octane gas and HIGH gas prices in SoCal

        You people....  In Oregon it's against the law (for some
IDIOTIC reason) to pump your own gas.  Therefore CHEAP gas in the
Portland metro area is 1.49 right now for 86 octane!!  And it'll go up
even more in the next few weeks.
        The OPEC oil ministers have agreed to "limit production" by a
LARGE (forgot exactly HOW much) margin.  This is supposed to tighten
the oil supply and raise oil prices to near $18/barrel.  Funny,
though, how quickly our costs rose, considering how long it takes to
get from oil being pumped in Saudi Arabia to the gas pump at the
corner Texaco....
        Now, BACK to GPL and NR99!!

Only if it pings on 91.

:> Is there any advantage of buying 93 octane over 91?

: Only if it pings on 91.

I don't remember hearing it ping on 89...  gas in the midwest is not always
consistent though.

Guys, this DEPENDS ON YOUR CAR!  Audis (and most other cars in
this cross-posting) built in the last DECADE have knock sensors
on the engine.  When any 'ping' (the most correct term is
'premature detonation') is detected, the timing is retarded.
Because this is almost instantaneous, YOU will never hear it.
But you WILL feel it because retarded timing produces less power.
It may be that there is no difference between 93 and 91 octane
fuels, but then again, there may be.  You'll have to be the judge
and it will depend on what you're driving and how you're driving
it.

I wonder if this retarded time is what causes E34's 6cyl engine to act
boggy when taking off at the light occasionally.  I've read other
posts by other people about this before.  I get 34mpg on the road if
I drive 65 in the winter so i'm not complaining about fuel economy.

Regarding the quote above... My 525i gas cap states a minimum AKI 89 fuel.  
I'm not sure if that is the same scale as the octane rating that I'm
accustomed to seeing at the pump.  I know there are several different
scales used for measuring octane ratings.

My concern with premium fuel has always been that not enough of it sells
at the pump, and consequently may sit in the tanks at the station for
long periods of time.  I wish I had a litmus-type tester for fuel so
I could tell the true octane rating of the fuel, its quality, moisture
content, etc.  I get a little jittery when I fill up and notice the
87 octane pump looks like it had pumped billions of gallons while the
premium 93 octane pump looks like it has never been used before.

I haven't done enough driving  with different octane ratings of fuels
to judge if 91 beats 93 in my car but the extra price is worth it to
me if I will prolong the life of the engine.

   The biggest thing to remember is what ever you decied to use, make sure
its alway the same octane...It will slighly change your computer and going
back and forth will not bennifit your engine!
