[net.auto] carb cleaners and octane

dlp@akgua.UUCP (D.L. Philen [Dan]) (12/14/84)

     My 78 toyota celica (77k miles) acted like its choke was
sticking so as a short fix I added some carb cleaner.  This is the
stuff you pour in the tank and it is supposed to clean the carbs
as you drive.  Anyway, the result was the the car seemed to perform
a whole lot better.  The car has always worked better on the highest
octane gas I could get.  With the carb cleaner it seemed to
accelerate better without hesitation or knock.  I also
have a 1964 sedan (4450 pounds with 6.25 liter V8) that marginally
runs great on 92 octane.  If I use Texaco 93 octane then I only
get a little knock when I stomp on it.  I poured the carb cleaner
in it too, and it also seems to run better.  

     My question is this,  Is it just my imagination or does
carb cleaner really increase the octane rating.  If it does then
why not use this instead of the more expensive octane boosters 
available.

I know nothing about carb-cleaner (of the in-tank variety), but anyone
who is using expensive octane boosters on your good old 10.5/1
V8 is missing a great thing.

Ask your neighborhood chemist sometime, what happens when you react
napthalene with your basic gasoline.  I do not know the actual reactions,
(I can point you to someone who has run through them all, if you are
interested), but the end result is a very clean and very noticable
increase in the 'octane rating' of the gas.  I have a good friend
whose modified (now hemi-head 11.0/1) 327 runs great on either one 
of the following:
	
	1] 76 Super Leaded 93 Octane or

	2] any 88-89 octane regular leaded fuel and a small amount of 
	   labratory grade napthalene.

You know, labratory grade, pure napthalene.  The stuff labeled
"Moth Balls" at your local store.  3 balls/gallon, I kid you not.
