The three main risk factors to small engines are stale gasoline, ethanol content in gasoline and fuel contaminated with dirt or water. It is these fuel-based risk factors that keep small engine repair shops open for business in every town and city in the nation. While we appreciate the well being of this little sector of the economy, we can offer an inexpensive product that will protect your small engines from all of these risk factors. That product is AMSOIL Quickshot Small Engine Gasoline Additive. Quickshot keeps your engines running at peak performance, while lowering down time and trips to the repair shop.

Small Engine Risk Factors

Gasoline with Ethanol Content

Virtually all regular and mid-grade gasoline sold in North America contains between 5% and 10% ethanol. This is fine for your car, but not good for your 2-stroke or 4-stroke small engines. Ethanol is very prone to soaking up moisture that can appear though condensation or show up in the fuel supply. Once the ethanol mixes with this moisture, trouble is around the corner. This mix forms a ball in the bottom of the fuel tank that creates gummy deposits that plug carbs and fuel lines. Eventually this “ball” of ethanol and moisture passes though the engine and when it does, a dangerously lean condition can occur (with engine seizure being the ultimate risk). Boats and snowmobiles are especially prone to this condition with their natural exposure to moisture. Lawn and garden equipment and other dryland powersports equipment are certainly at risk as well.

AMSOIL Quickshot neutralizes this ethanol/moisture mix allowing it to pass safely through the engine and also prevents this gunk from forming deposits in the fuel system or engine itself.

Stale Gas

The number one risk factor that keeps small engine repair shops humming is stale gasoline. To put it bluntly, today’s gasoline is crap. After 30 days in a small engine fuel tank or jerry can, the energy content and quality goes downhill very rapidly. Bad fuel makes starting difficult and creates harmful deposits in the carbs, injectors and fuel lines. AMSOIL Quickshot preserves fuel over the medium term, so that you have “in-season” protection from bad gasoline. For off-season or long term gas preservation, we use AMSOIL Gasoline Stabilizer.

Contaminated Gasoline

Water or dirt can be present in engine fuel tanks, gas cans or even at the pumps. AMSOIL Quickshot neutralizes contaminated fuel so that it passes through the engine without issue. Quickshot diffuses water so that it cannot cause starting or operational issues.  When it comes to dirt, Quickshot’s detergent content breaks up particles so that it cannot create deposits that may block passages.

Cleans Fuel Systems and Combustion Chambers

A clean engine runs like a top and starts easily every time. Throttle response and engine output is optimized and downtime is minimized. AMSOIL Quickshot contains a potent detergent package that cleans deposits from carbs, fuel injectors, fuel lines and even hard carbon from combustion chambers and spark plugs.

Oildepot Tip

As mentioned, ethanol and small engines are bad news. For all of our small engines, we use only premium gasoline that does not contain ethanol. Many small engines call for premium gas anyway. In fact, to make double sure that no regular or mid-grade gas makes its way into our gas can, we pump the first few litres of premium into our truck’s tank first to drain out any regular fuel that may be left in the pump or hose.  While the ethanol risk may be alleviated by using premium gas, we still faithfully use Quickshot in every batch to keep engine internals clean, preserve the gasoline and deal with any contaminants that may be lurking in the fuel.

Water/Ethanol Separation in Gasoline

Suitable Applications for AMSOIL Quickshot

AMSOIL Quickshot Small Engine Gasoline Additive can be used in any gasoline-powered small engine or powersport application with two- or four-stoke engines. Quickshot is suitable for engines with carburetors or fuel injection. Examples include:

  • Lawn/garden implements
