If you own a motorcycle, car, lawnmower, boat, ATV, or any gasoline operated engine, you know you need 100% Synthetic AMSOIL Synthetic Oil and lubricants to extend the life of and protect your investment. If your engine sits for more than a couple weeks between uses, you need AMSOIL Fuel Additives such as AMSOIL Gasoline Stabilizer to keep your engine from rusting because gasoline doesn’t keep.

What to do with an Engine Not in Use

The best advice is "don’t let your engine sit with gasoline in it and go unused". Running your vehicles every week or two at the maximum until fully warm is the best way to prevent fuel delivery problems with contemporary gasoline. When you can’t run them, here’s what you can do to minimize problems with motorcycles, your generator, string trimmer, lawn mower and even chainsaw. Do you get it Edmonton? I'm talking about anything that runs on gasoline and may sit idle.

Half Full, Half Empty

On carbureted bikes with steel gas tanks, half the fuel system should be drained, and the other half kept full. Carburetors and their tiny air passages and jets can become plugged with aged fuel that deteriorates into sticky varnish over time. Since carb internals are made of non-ferrous aluminum, brass, plastic and rubber that won’t rust, if it’s practical to drain them (shut off the gas manually first or look for a vacuum-operated-type petcock that is off whenever the bike is), this is your best bet for trouble-free operation when refilled. Most carburetors have drains in the bottom of their float bowls operated by turning a screw. Don’t over tighten that screw, and only drain carburetors (into something, not just onto the bike and floor) when the bike is off and cold, then run the bike until it dies to suck the rest out. If you’re clean and careful, there’s no reason you can’t return the drained fuel to the tank.

Fuel Stabilizers

Steel tanks on carbureted or fuel-injected bikes can rust inside, so it’s best to leave them at least 3/4 full of fuel to which you have added an AMSOIL fuel stabilizer. Some newer models have plastic-shrouded aluminum or plastic tanks, in which case it’s up to you, but make sure you stabilize it if you leave fuel in the tank. In really humid environments, keep an aluminum tank full.

Fuel Injection Systems

Fuel injection systems seem much less susceptible to the ravages of stale fuel, and once full of stabilized fuel are almost care-free. In fact, some manufacturers warn against running their EFI bikes entirely out of fuel. Use AMSOIL Quickshot when you're ready to roll to thoroughly clean and restore peak performance in small engine and power sports equipment fuel systems.

Carry Amsoil Synthetic Oil and Lubricants with You to the Pump

If you can’t drain carbs, after adding stabilizer to the fuel in the tank run the bike long enough to ensure stabilized fuel has filled them, then shut off the bike and petcock. Carry a small bottle of stabilizer when you take out one of your less frequently ridden bikes, and add it to the gas station before riding home. Err on the side of adding more stabilizer. You can’t overdose with the AMSOIL Synthetic Oil products. Stabilized fuel in the carbs does not guarantee that they won’t suffer from plugged passages or jets, however, and you should still run bikes kept this way at least every three weeks. More often is simple insurance that you won’t need an expensive carburetor overhaul. Run the engine until it’s fully warm to burn off water and contaminants in the oil and exhaust. Pump the fork and shocks and work the brakes, clutch and shifter to keep seals flexible and lubricated.

Protect Your Engine

Most of the gasoline sold today in the United States contains ethanol, and the percentage is expected to increase over the next few years. Gasoline and ethanol are delivered to the gas stations separately and are blended at gas stations during delivery. So what are the effects of ethanol in gasoline, and what can you do to prolong the life of your engines running on ethanol-blended fuel?The potential problems with small engines are even more devastating.  Since ethanol is added to gasoline as mandated by the EPA to lower carbon emissions to make the running of such engines more eco-friendly. Ethanol-blended fuels left untreated can start “phasing.” Phase separation is when ethanol in the fuel absorbs too much water, and separates from gasoline by dropping to the bottom of the tank since the ethanol and water mixture that results from phase separation is heavier than gasoline.

Water-ethanol solutions can damage fuel systems and engines, and the system will need to get flushed to prevent further damage. Once phase separation has occurred, no fuel additive can reverse it, and the fuel tank will require draining. If the fuel and ethanol have completely phase-separated, the fuel in the tank will be unusable and must be drained. Mechanics offer ‘pump-out’ services to drain and flush the fuel system.Be careful on what you hear, as there is no magic ingredient to reverse phase separation after it has already dropped to the bottom. The easiest defense against phase separation is to use AMSOIL Gasoline or Diesel Additives and to keep the tank almost full at all times, allowing a little space for the fuel to expand in warmer weather. Moisture comes from space in the tank so reducing the amount of air in your tank will reduce the amount of water that can enter with the air. This is especially important when you are dealing with equipment designed with an “Open” fuel system such as many small non-road engines and watercraft.

Engine Corrosion

Ethanol may contribute to corrosion of fuel tanks and other fuel system components at a rapid rate. It is very important to pour in an AMSOIL fuel additive that guards against corrosion every time you fill the tank; this is especially true with small engines since many still use aluminium parts that corrode more quickly resulting in oxides that look like white rust. Another issue with ethanol mixed gasoline is that ethanol can loosen debris that normally collects in the corners of the fuel tank and can lead to clogged fuel systems. Again, adding a synthetic fuel treatment such as AMSOIL Diesel Injector Clean that contains cleaners will allow for these dirt particles to pass through your system.


It's important to note,  that gasoline “oxidizes” when exposed to air. That is, it loses its volatility over time and may turn to varnish. Using a quality fuel additive like AMSOIL Diesel Recovery Emergency Fuel Treatment that will address all of these issues will help you enjoy your gasoline-powered small engines and boat worry-free for years to come. The good news is that E-10 has been used in many parts of the country for over 25 years, so there are proven ways to protect your engines from the potential hazards your engine may face with gasoline sitting unused in the tank for extended periods.

Protect Your Equipment

Use an AMSOIL fuel stabilizer and treatment in your fuel system at all times.  Especially, recommended for engines that sit for a lengthy period. The more the vehicle/equipment is used, the less likely it is to have problems. If you don’t plan on using it for a while, keep your tank 95% FULL to prevent any condensation but still allow room for expansion. It’s important to avoid water intrusion into your fuel system. Make sure only to buy fuel from a reputable gas station with a good turnover of product to ensure you are getting fresh gasoline. Rubber fuel lines older than the mid-to-late 1980’s should be inspected and may need to be replaced since they may not be compatible with ethanol fuel.

AMSOIL Fuel Additives and Gasoline Treatments

AMSOIL Fuel Additives and Gasoline Treatments formulations contain a chemical that absorb water that help prevent phase separation. They use a non-alcohol water remover that bonds with water molecules, thereby allowing excess water to pass through the engine and out the tailpipe without causing damage. However, please note that large amounts of water in a fuel tank can result in lower power acceleration, if not engine damage and failure. If too much water is present in the fuel tank, the tank will have to be drained and replaced with fresh fuel and additive. The tank must be completely dry before new fuel and stabilizer are added.  To help reduce the amount of water in a tank, it is important to keep it full whenever it sits unused for any amount of time.  Water molecules are introduced into the air in the tank, and the less space a tank has, the less air and water that will be present. These treatments are designed to protect ethanol-blended fuels against water attraction, varnish formation, and corrosion.  The ethanol treatments help protect automotive, small engines and marine engines from these issues. Like the AMSOIL Motorcycle Octane Boost, fuel additives protect fuel for more than just one tank.  However, because ethanol is in your tank every day, these treatments are recommended during every fill-up.
