Is it a waste of time even thinking about using these? Anyone have any positive results?

 

In short, boosters are bad...Follow this thread..

You can add Toluene or Xylene to pump gas. It is a normal component of gasoline. I believe it is 111 or 114 octane. Some have argued that it is harmful, but since it's normally in gasoline I think it's OK.

You can add salt to your cake. Salt is a normal component of
most cake recipes. Some doctors say it's bad for your health
but since it's in there anyway it might be good...

I exagerate... But there are two issues still:

1 - Unless the car is tuned for the increased octane, you have
two sub-issues:
1.1 - The motor is not likely to take advantage of the extra
detonation-resistance. It's not going to dial in any different
timing, because it doesn't know there's special gas inside it.
1.2 - If the motor doesn't completely combust the mixture
(this *might* be a problem when the motor's cold. Remember
that anti-detonation implies resistance to combustion too)
toluene is very sooty when incompletely combusted, and
you might clog up your cats a bit.
2 - Unless you ensure the gas is homogenously mixed, you're
running with variable octane, so even if you have a 100-octane
program, you may be running 110-octane for 5 minutes and
93-octane for a minute...

I vote for expending almost zero effort to 'gild the lily' unless you
are already playing with the DNA of the car like Chad.
