AMSOIL Quickshot® Gasoline Treatment and Stabilizer

Helps prevent water-induced ethanol separation and breakdown. Cleans gummed/dirty injectors and carburetors. Cleans carbon deposits to restore engine performance. Protects against formation of gum/varnish buildup in tanks and fuel systems. Designed for use in all two- and four-stroke gasoline-powered engines, including motorcycles, snowmobiles, boats, ATVs/UTVs, edgers, tillers, mowers, snowblowers, chainsaws, generators and farm/construction equipment. One 8-oz. (236-ml) bottle treats up to 6 gallons (23 litres) for cleanup and up to 12 gallons (45 litres) for continued protection. For best protection, use with every tank.

CLEANS FUEL SYSTEMS

  • Cleans varnish, gum and insoluble debris that clog carburetors, fuel injectors and fuel filters in powersports equipment and small engines.
  • Quickly detaches and carries away fuel-system deposits, while also cleaning hard-to-remove deposits on piston tops, spark plugs and other combustion-chamber parts.
  • Helps reduce pre-ignition, rough idling and poor throttle response, restoring peak performance.

FIGHTS ETHANOL PROBLEMS

  • Designed to keep water due to ethanol dispersed in tiny molecules throughout the fuel tank, moving it out as a normal part of operation.
  • Helps maintain engine performance and protects against damaging corrosion.

  • Decreases the chance of ethanol separating from the gasoline, helping prevent lean-burn and combustion-chamber damage.

Applications

Quickshot is designed for an initial clean-up dose of 8 oz. (236-ml) per 6 gallons (23 litres) of gasoline, followed by 8 oz. (236-ml) per 12 gallons (45 litres) thereafter. Slight over-treatment has no negative consequences.

Ethanol

Ethanol in fuel tends to absorb water and separate from the gasoline (a process known as phase separation ), sinking to the bottom of the gas tank where it 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. 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% ethanol. Controlled plugging of injectors showed a 70% flow improvement, while oxidation stability improved 44% over untreated fuel.

Water

Water finds its way into fuel tanks through gas pumps and environmental conditions like condensation. It causes hard starting, performance degradation and corrosion problems if left untreated. 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 protect against damaging corrosion.

Dirty Gasoline

Dirty gasoline causes fuel-system gumming and varnish, as well as piston and combustion-chamber deposits. All gasoline sold in the U.S. is formulated with a lowest additive concentration (LAC) of detergents, but these minimal detergent requirements 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 to help prevent buildup in fuel systems, injectors and carburetors, while also cleaning hard-to-remove deposits on piston tops, spark plugs and other combustion-chamber parts.

and Powersports Equipment

Degraded fuel leaves behind varnish, gum and insoluble debris that can clog carburetors, fuel injectors and fuel filters in small engines and powersports equipment. Additionally, carbon buildup can form on the pistons during combustion, causing pre-ignition, rough idling and poor throttle response. Fuel-related problems are expected to become more common as the ethanol content in pump gasoline continues to increase. AMSOIL Quickshotis a premium fuel additive formulated to thoroughly clean fuel systems, restore peak performance and stabilize fuel during short-term storage. Its revolutionary technology focuses on addressing the three primary fuel-related issues plaguing small-engines and powersports equipment: ethanol, water and dirty pump gas.

A must have for seasonal machines

5.0 / 5

I add this to the fuel for both ATV and dirtbikes to prevent having fuel injector or carburator gumup issues. I have not had any issues since I started using Quickshot. This is a must have in my book.

Keeps my Small Engines Running at their Best

5.0 / 5

First received a free bottle during one of AMSOIL's promotions and didn't think much about it. Then I read some of the reviews and product information and wanted to try it out. I now purchase the big bottle, 1 quart, and run it in all my small engines (Stihl backpack blower, generators) to clean and prevent build up in the carburetors / fuel lines.
