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).

Just tried it for the first time in my woodspliter that only gets used a couple time a year.The last couple years its been getting hard to start and it surged slightly at an idle.
After treating fuel with Quickshot, woodspliter soon became easer to start and smoothed out the surging also. Must have helped the ethanol problem (maybe even some old sludge?).
So far I think it's very good product.

I started running this in my motorcycles and I noticed the difference after the first tank. My GoldWing seems to run more smoothly and the power curve improvement was noticeable, on a bike that needs no improvement. But the big difference was with my Harley. More power immediately, and it runs much more smoothly, but it also stopped backfiring when I roll off the throttle, which was a welcome change. I recommended this to two of my brothers and their experiences were identical to mine. We are all raving about Quickshots!

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.
