Degraded fuel presents a major maintenance issue in
small engines and powersports equipment. It can form
varnish, gum and insoluble debris that clog carburetors,
fuel injectors and fuel filters. Carbon buildup can
form on the tops of pistons that leads to pre-ignition,
rough idling and poor throttle response. Fuel-related
problems are only expected to intensify in the coming
years as the ethanol content in pump gasoline continues
AMSOIL Quickshot® (AQS) is a premium fuel
additive formulated to thoroughly clean and restore
peak performance in small engine and powersports
equipment fuel systems. It also stabilizes fuel between
uses and during short-term storage periods. Its revolutionary
technology focuses on three major fuel-related
issues plaguing small engines and powersports equipment:
ethanol, water and dirty pump gas.
Ethanol in fuel has a tendency to absorb water and
separate from the gasoline, sinking to the bottom of
the gas tank, where it quickly degrades and creates
gum, varnish and other insoluble debris that can plug
fuel flow passages and negatively affect engine performance.
When this ethanol/water mixture is pulled
into the engine, it creates a lean burn situation that
increases combustion chamber temperatures and
can lead to engine damage. AMSOIL Quickshot is
designed to keep water dispersed throughout the tank, moving it out as a normal
part of operation and decreasing
the chance of ethanol separating
from the gasoline.
Quickshot was tested in
fuel containing 10 percent ethanol.
Controlled plugging of injectors showed a 70 percent
flow improvement, while oxidation stability improved
44 percent over untreated fuel.
Water finds its way into gas tanks through condensation
in tanks open to the atmosphere, gas pumps and other
environmental conditions, and if left untreated, will cause
a myriad of starting, performance and corrosion problems.
By keeping water dispersed in tiny molecules and safely
moving it out of the tank through the combustion chamber,
Quickshot helps maintain engine performance and
protects against damaging corrosion.
Dirty gasoline causes fuel system gumming and varnish, as
well as piston and combustion chamber deposits. Although
all gasoline sold in the U.S. is formulated with a lowest additive
concentration (LAC) level of detergent additives, these
detergent levels are not enough to prevent deposits from
building up on critical fuel system components. Quickshot
contains unique chemistry that quickly detaches and
carries away deposits and buildups in fuel systems, injectors
and carburetors, while also cleaning hard-to-remove deposits on piston tops, spark plugs and other combustion
Quickshot is recommended for use in all two- and four-stroke
gasoline-powered engines, including motorcycles, snowmobiles,
boats, personal watercraft, ATVs, edgers, tillers, mowers, snowblowers,
chainsaws, generators and farm and construction equipment.
However, AMSOIL P.i. Performance Improver is the superior choice
for passenger vehicle applications.
Quickshot is designed for an initial clean-up dose of 8 oz. per
6 gallons of gasoline, followed by 8 oz. per 12 gallons thereafter.
