$1.13!?!?!?  I live in Redmond Washington and the cheapest gas is about
$1.40!!  In richland Wa. it's about $.89!  

BTW, I think it was Arco that finally stated that the octane didn't make
any difference in performance.  I think it was the first and only company
to say this!

Hardened valve guides.  Mainly changes to the valve train, as this is the
main effect, besides the obvious loss of ping-retarding characteristics
from leaded fuel.  I think the exhaust valves are also a different compound
than standard.  I've heard one way of getting around rebuilding the head,
is simply using Marvel Mystery Oil, or other applicable light oil.  This
will protect the valve train.


>Also, what type of petrol is available in the US now? In England we have
Four Star (98 Octane leaded), Super Unleaded (98 octane) and Unleaded (95
Octane). Super Unleaded is required for some performance cars but is not
readily available anymore because of scares about its benzine content.

Gasoline in the southeastern US is available in 87, 89, and either 92 or 91
octane ratings, but I'm not sure if these numbers are valid for comparison
with Euro octane numbers.  I think we may use RON + ???/2.  Basically an
average of the two standards, while you guys use only one rating.  Could
someone on the list enlighten further?


I am not certain about the benzene concentration in your Super Unleaded,
but realistically, I would not worry too much.  In some of my OSHA(safety
and health regulatory agency here in US) 40-hour training for environmental
workers, I remember getting an instrument out and sticking this into the
gas tank of my MGB.  It basically pegged the meter as far as benzene is
concerned.  The concentration of benzene, while quite high, isn't enough to
cause problems, unless you are a gas station attendant and are exposed to
fumes for lengthy times(years).


I would imagine the biggest impact to your country might be the expense of
using gasoline with more additives to raise octane.  I imagine this gas
would be more expensive.

But then I look at the 92 octane premium gas here in Atlanta, GA for
$1.13/gallon, and I wonder how cheap it really is to make.  

I think the main reason for cheap gas here is the fact that Atlantans
combined put over 1,000,000 miles(1.6 Million km) on the roads each day. 
More than any other city in America and possibly the world.  Pathetic!
