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 to increase.
Package sizes include:
8-oz. Bottle
Quart Bottle
Quickshot SE 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.
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 to increase.
AMSOIL Quickshot SE (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 SE 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 SE 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 SE 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 SE 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.
Quickshot SE is designed for an initial clean-up dose of 8 oz. per 6 gallons of gasoline, followed by 8 oz. per 12 gallons thereafter.
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

I use this in my RZR's at every oil change to keep my valves clean and fuel pump clean.

Best fuel additive to remove water, moisture, and keep carbs and injectors clean. This is for small engines it says and always used on my lawn tractor. Used this for 6 years and took carb apart to clean and it needed no cleaning. Also stored with fuel during winter and still always started after winter with only two turns. Now I use it in both my 2010 Honda Ridgeline and 2002 Infiniti Q45 to keep the injectors and fuel lines clean and it has improved the mileage in both vehicles.

Use Quickshot in all my bikes.

Stellar results one bottle with fill up.
All 3 bikes run smoother slight increase in smoothness, responsive at roll on. Clearly cleans injecteters along with fuel system. With one treatment.
In my humble opinion best fuel additive I've used. I have tried most of the others on the market. But AMS Quickshot delivers best results used regularly.

The best cleaning products out there
good product Quick shots works fantastic on idling and response
I have a 2004 Chevy cavalier I bought it when I had 60,000 km on it I know I put Amsoil signature series since day one Which was six years ago in the motor ATF Blue automatic transmission fluid in the transmission. and also I beat the crap out of my cavalier It has 267,000 km on it Now. and no loss of horse power does not burn oil smooth idling no slipping in the transmission whatsoever I expect this car to last for many more years to come.. one of the best oils out there in my opinion there is evidence about this product that amsoil has been the best most Money saving Lubricant out there do your homework you will see
it love Amsoil products !!!
