I'm famous-notorious for driving the oldest vehicles in the neighborhood
(eg - 6 yrs ago, my daily driver was a 1967 Olds 88) so when I had to
upgrade after the rear bumper fell off my 1979 Cutlass due to frame rot, I
decided to upgrade to something from the 21st Century.
So I now own a just-off-lease Cavalier Z24 5-speed which is loaded, and
also my first ever FWD car, but is actually kinda fun to drive. Miles of
smiles so far. But I keep seeing ads for "fuel injector cleaners" and
finally bought some today, thinking that these newer cars are more finicky
and maintenance-needy than my old carbureted dinosaurs.
Pop the seal on the STP bottle, and damned if it doesn't smell like
old-fashioned Kerosene (only 100X the price).
Bottom line: are these additives beneficial in any way, or am I a victim of
marketing hype? Any experience here?
