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).

Used this product in a Polaris four wheeler that had not been run in three years. It had been left with stale fuel in it and would not stay running after draining and adding fresh gas. I drained again and added product to fuel. The quad ran a bit ruff, but by the end of tank was running and idling perfectly.

I use this stuff to clean up my FI after a long winter storage. First run the fuel in the tank down so the low fuel light cime on, then at a gas station pour this good stuff in the gas tank before filling it up.

Small engines sit for long periods in all kinds of weather and with 10% alcohol in the fuel, water is a problem. Quickshot removes the worry. All of my outdoor equipment use it and I have never had a problem.

I use Amsoil Quickshot and Fuel Stabilizer in my motorcycles to avoid the problems associated with the fuels we have today. There are times when my bikes will sit for several weeks and I don't trust leaving fuel in them that long without any additives to keep the fuel from breaking down. I have had good results with Amsoil products and I believe using these products keeps my motorcycles running great.

I use Quick Shot in my motorcycle on the first tank of gas every season. I use Quickshot on 5 snowmobiles on the first fill up each season as well!
I also use Quick Shot every time I fill up my 2 gallon gas can that I use to fill up the lawnmower, snowblower etc. This way I never ever have starting or smooth running problems with any of my equipment.

I just inherited a riding mower that has sat in one place for 7 years. I put new gas in it. It would not start. I added some quick shot gas additive. Mower started right up and runs great. Thank you quick shot

Every couple of months I dump a bottle of Quickshot into each of my fuel tanks on my 95' F-150. I have fast startups no matter the cold (I'm in Wyoming!) and have had no problems relating to Ethanol in the gas. All of my Jerry Jugs get a shot of Quickshot in them no mater what gas engine they service. Sthil chainsaws, weed eaters, lawnmowers, outboards etc. are all treated with this great product. Have had no fuel related problems.

Honda 30 hp outboard motor was idling poorly and difficult to start. Started using Quickshot in the spring and after 2 tanks of gas, the motor is idling much better and starting has improved. The motor is 12 years old so I believe it will take a few more tanks of fuel with Quick-shot to get the motor to perform at its best.
Great product but ...
One of the bottles leaked. I had a strong smell for months in my suv. The product worked great. It's cheaper than ring free and seems to work better
