P.I. Performance Improver
Concentrate (API)

AMSOIL PI improved fuel economy by
reducing port fuel injector deposits, intake
valve deposits and combustion chamber
deposits in 100% of the vehicles tested!

Reformulated for greater potency
Series 2000 Octane Boost (AOB)

Maximizes power and improves
performance in all two-cycle and
four-cycle gasoline engines. Increases
octane number up to seven points.
Reduces engine knock, improves ignition
and engine response, helps fuel burn
cleaner and inhibits corrosion.
Recommended for off-road and racing
use.
Diesel Concentrate Performance
Fuel Additive (ADF)

Total system cleaner and lubricity improver
for all types of diesel engines. Improves the
performance, fuel efficiency and longevity of
diesel engines while reducing deposits,
black smoke and emissions. Improves fuel
economy by cleaning dirty injectors and
restores horsepower. Designed for use in
heavy-duty diesel engines.
Cetane Boost Diesel Fuel
Additive (ACB)

An ashless, alcohol-free additive
that improves cetane up to seven
points for increased power and
performance in all diesel engines.
Diesel Cold Flow Improver (DFF)

A premium fuel additive that lowers diesel
fuel cold flow properties as much as 20°F
(11°C).
Gasoline Stabilizer (AST)

It is difficult to drain all of the fuel from
equipment before storage, and doing
so would expose the system to other
problems, including the formation of
rust and corrosion on the bare metal in
the tank and fuel system and the drying
and cracking of gaskets and seals.
Some fuels are pre-treated with
oxidation inhibitors that allow them to
be stored for short periods without
forming excessive deposits, while
other fuels have no inhibitors at all.

AMSOIL Gasoline Stabilizer (AST)
reduces the oxidation process that
occurs when fuel is stored for
extended periods, improving
performance, extending equipment life
and decreasing maintenance
expenses.
