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, causing 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 to increase.
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. Its revolutionary technology focuses on
three major fuel-related issues plaguing these applications: ethanol,
water and dirty pump gas.
Ethanol
Ethanol in fuel has a tendency to absorb water and separate from the gasoline (a
process known as phase separation), 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 fuel 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
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 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
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
chamber parts.

APPLICATIONS
Quickshot (AQS) 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.
RECOMMENDATIONS
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. Slight overtreatment has no negative
consequences.
