[Mgs] Old Gas

[COX, DENNIS]

I have heard that the new formulations of gas have a shorter shelf life
then the old formulations.  It's a matter of a few months.  Not sure how
true that is, its just what I've heard.  I am about to start my rebuilt
engine in my 67 B.  Rebuilt with a 286 degree duration cam and 68CC
combustion chambers. Should be about 10:1 compression.  I drained the
gas this last weekend after it had been sitting about 8 months.  It did
have that old gas smell but looked okay.  We poured it into my friends
68B.  I haven't talked to him yet to see how its been running.  But
these new formulations are the color of piss and have a funny smell
anyway.  I bought 5 gallons of race gas, 110 octane leaded.  It was pink
and smelt like I remember gas to smell!!  Took me back to the old days.
When gas was good enough to clean parts in.  If nothing else... Id
dilute the old gas with some new.  I imagine it looses octane with age
also.

When is gas too old to use?  I have about half a tank of gas in my MGB
that
has been sitting for about 1 year.  I am finishing the rebuild of the
engine
and plan to fire it up later this month.  Should I dump the gas first or
should it be OK.  I live in Los Angeles and the car has been stored
outside
during this period.
