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).

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.

This stuff is amazing. Even passed it along to some friends and all I get back is "could even get it to barley run, but after a few minutes of running with this and it's like brand new". I have the same experience, use it in the ATV's, riding mower that was rough running, gas powered brush hog, generator and my boat that wouldn't idle below 1,900 rpm. Put this in and after a few minutes, it was idling no problem. My boat has never started this good and with such ease. Going to use it in the snowblower this winter, can't wait.

Shortly after Quick Shot hit the market i began having lots of small engine problems. After many trips to several different mechanics with out any success i started researching for new equipment, i thought that i had just worn these out (weed-eater, blower and chain saw). Then i remembered reading in one of my Amsoil magazines about this new product "Quick Shot" and how after one tank of fuel there would be a noticeable difference in how well an engine operated. i couldn't believe the difference this product made and it was accomplished before the tank was empty. i'm still using the blower and weed-eater to this date. i also passed a free bottle along to a friend who was having problems with a four wheeler, long story short, this product reverse his poor running machines also. This friend ordered a case shortly there after. Amsoil Quick Shot is and will always be an essential ingredient to my small engine fuel.
