thing | am trying to bring cut is tina
any such claims as SO per cent savinl

simply grossly exaggerated or clear at
tempts to mislead.
! 1 can readily understand how an in
| crease in power can be had by the us
| of some substance in the fuel. If the
| chemical structure of the fuel is altered
| by some action of the substance, the
| power can be increased This can be
easily explained on the theory that the
| fuel burns strata by strata and that
each strata gives its own individual re-
suits. If the strata, or series of com
! pounds composing the gasoline, are
| changed chemically certain way, they
can be given higher explosive force in
| dividually, so that the maximum i'm
pact on the pistons also will be greater
and the result will be in evidence il
more power from the engine.
In regard to the carbon question.
think you will find that these fuel adul-
| terants will not remove a deposit al
ready hardened, but in some cases they
might prevent depositing of carbon, bu
that practically the same results nigh
be had by feeding a little oil with the
gasoline. The trouble here would be
however, in getting an oil that wouldn'
burn up with the explosion. If it we
the piston top, then the carbon wouldn'
have a chance to deposit, or it would a
any rate be of the loose sort. I believ,
the carbon removing feature a sham il
nearly every case, because the carbon
once caked cannot even be removed
easily by scraping. Often we must US,

One thing more about these adulter
ants, their price. Where the maker doe
not give money back guarantee, anC
where the manufacturer has no recog
nized standing, | think the motorist i
gambling, and such gamblers nearl,
always lose. The usual price for thes
| substances is high, not because the in
gradients warrant it, but because tn,
maker wants to make more money thai
he is entitled to. The can or bottle i
usually worth more than the contents
1t would be wise for the motorist be
fore purchasing any of these sub
stances to find out from the dealer i
he will return the purchase price if tn
stuff does not live up to the maker
claims.
