Why should a boat gas tank never be full?
How to fog a car without starting?
For complete engine fogging, pull the spark plugs, spray fogging oil into each cylinder and turn the engine over ( without starting the engine).
Can you winterize a boat with ethanol?
Ethanol-laced fuel has changed some of the rules for winterizing marine gasoline systems. When prepping a boat for winter storage, boat owners must now do all they can to avoid phase separation — a phenomenon in which ethanol combines with water and separates from gasoline, descending in a soupy goop to the bottom of the tank. While this can occur at any time, it is more likely to happen when gas is stored for long periods.
How to treat boat fuel for long term storage?
How to Treat Boat Fuel for Long-Term Storage. Plan your late-season boating trip to use up most of the current fuel. Fill the tank with fresh fuel so it's almost full. Be sure to use gasoline that does not contain ethanol. As you fill the tank for storage, add a marine-specific fuel stabilizer additive. Follow all instructions outlined on the fuel ...
What is proper fuel treatment?
Proper fuel treatment is a key element of any long-term boat storage preparation plan. When handled correctly, starting your boat next season can be as simple as turning the ignition key. Neglect of the fuel system, however, can cause problems both inconvenient and expensive.
Why does my fuel tank contract?
The normal diurnal cycle of rising and falling temperatures—cooler in the evening and warmer during the day—and the fluctuations in temperature in many climates over a six-month off-season, cause any air left in the fuel tank to expand and contract. The tank “breathes” though its vent, and draws in air that is often very damp in the winter months. The moisture in that air can be absorbed by the fuel if it is an ethanol blend (E10) or condense on the sides of the tank, especially if the tank is metal. In either case you could be left with water in the bottom of the fuel tank come spring, which can foul the entire fuel system, cause the formation of deposits or corrosion in the bottom of the tank, and other issues.
What happens if you put water in the bottom of your fuel tank?
In either case you could be left with water in the bottom of the fuel tank come spring, which can foul the entire fuel system, cause the formation of deposits or corrosion in the bottom of the tank, and other issues.
Can you store a boat with a full fuel tank?
Marine engine manufacturers and technicians advise storing any boat with the fuel tank almost full, leaving just a little capacity to accommodate expansion of the fuel if the temperature warms. Filling the tank displaces any air in the tank and eliminates the opportunity for condensa tion to form inside the tank while the boat is being stored. This can occur if the boat is stored outdoors or in an unheated building.
Can you use gasoline in a boat?
The trick here is to plan your late-season boating so that you use up most of the fuel in the boat’s tank, and then fill it with fresh fuel just before it’s prepared for storage. Use gasoline that does not contain ethanol if that product is available where you live.
Does a fuel tank breathe in the winter?
The tank “breathes” though its vent, and draws in air that is often very damp in the winter months. The moisture in that air can be absorbed by the fuel if it is an ethanol blend (E10) or condense on the sides of the tank, especially if the tank is metal.
Why do you need to use ethanol fuel in a boat?
Taking your boat’s fuel system into the top performance, efficiency and increased power. I recommend using it to protect your boat’s fuel system from damages of ethanol-based fuel and moisture. It protects the engine, especially the metal components, fuel combustion and even the engine is stored.
What is a marine fuel stabilizer?
The nature of a marine fuel stabilizer has made it a known and widely-used preventive marine fuel treatment. A fuel stabilizer can stop the chemical breakdowns and reactions of instability from starting in petroleum fuels. It treats a petroleum fuel’s quality while ensuring the performance of the boat’s engine.
Why do you need a fuel stabilizer for a boat?
Adding a fuel stabilizer to your boat helps protect your marine engine from ethanol-related damage. It will allow you to store your boat without worrying about the effect of ethanol fuels to your fuel system. You can actually use fuel stabilizers for your daily marine engine use, depending on the type of fuel you use in your boat.

This fuel stabilizer is formulated for use in all 2 and 4 stroke carburetor and fuel‑injection gasoline engines, including boat engines, cars, trucks, catalyzed engines and so on.
Why is it important to use fuel stabilizers?
The preventive nature of fuel stabilizers is that they are preventive treatment solutions. They stop the chemical reactions of instability from starting. They cannot take bad, darkened marine fuel or phase-separated ethanol and put it back together. That’s why it’s important to treat your marine fuel when it is at its peak of quality, to keep it that way.
How does ethanol affect boat fuel?
The ethanol in modern boat fuels attracts and absorbs water molecules, and any condensation in the tank will be absorbed into the fuel. Eventually the fuel becomes saturated, at which point phase separation occurs. Phase separation is the separating of the water/ethanol mix from the fuel, with the denser water/ethanol combination forming a layer at the bottom of the fuel tank. This corrodes the fuel tank, leading to oxidized debris that can block the fuel system. It can also get sucked into the fuel system when the motor runs again (most fuel systems take fuel from the bottom of the fuel tank), which leads to the fuel injectors or the carburetors needing to be drained, cleaned and serviced.
What is winterizing a boat?
Winterizing your boat’s fuel system is just a part of preparing the engine for an extended period of storage. Watch the videos below to see how to winterize a 2-stroke outboard motor and a 4-stroke outboard .
Why fill a fuel tank when winterizing?
Filling the fuel tank when winterizing your boat eliminates condensation from forming inside the tank, which contaminates the fuel and leads to damage to the boat’s fuel system.
What happens when you leave the fuel tank exposed to the air?
By leaving the inner walls of your boat’s fuel tank exposed to the air, you’re allowing condensation to form inside of it , and that’s not a good thing.
How long does it take for marine fuel to break down?
Add a marine-specific fuel stabilizer while filling the tank so that it thoroughly mixes with the fuel. Untreated fuel can break down within weeks, and marine-specific fuel stabilizer prevents this from happening while keeping the fuel fresh for months. Always follow the instructions on the fuel stabilizer’s label.
Can you use fresh stabilized fuel in a fuel tank?
Fresh stabilized fuel needs to get into the entire fuel system, not just the fuel tank. Old untreated fuel left in fuel lines, carburetors and fuel rails/injectors will destabilize, leaving behind varnish-like deposits that can easily block the fuel system. By running the motor for a few minutes, the new stabilized fuel will be pumped though the fuel system, protecting it throughout winter storage.
Is it better to fill up a fuel tank or store it?
When it comes to winterizing fuel tanks, some say it’s better to fill up the tank, while others say it’s better to store the boat with a fuel tank that’s nearly empty.
What are some examples of fuel storage additives?
They do not explicitly claim to prevent separation. Sta-bil Marine Formula Ethanol and Techron are examples of this type of product.
What are the problems with E-10 fuel?
Two of the most serious concerns were: The fuel acts as a powerful solvent, even dissolving some fiberglass tanks; and phase separation, when water in the fuel separates out of the fuel mix and drops to the bottom of the tank, where it can be sucked into the pickup feed or promote corrosion within the tank.
Why is gasoline refined?
Fuel oxidation and detergency to prevent gum and varnish formation. Unlike lube oil, refined gasoline is inherently unstable and wants to polymerize, so the refiner applies more additives to stabilize gasoline. These additives also add detergency, reducing engine and fuel tank deposits. They are not intended to clean tanks or emulsify water, but can help prevent dirt and water from attaching in the first place.
How much Sta-Bil is good for fuel storage?
Its Marine Ethanol treatment is a medium-green liquid that mixes easily with gasoline. It recommends 1 ounce per 5 gallons of fuel for storage protection, or 1 ounce per 10 gallons of fuel during the season. The high levels of additives in this product suggest that Sta-bils recommended doses are conservative. The product comes in 16- or 32-ounce bottles with built-in measuring dispensers. This product delivered exceptionally clean fuel/water separation.
How does phase separation affect octane?
A side effect of phase separation is that it lowers octane by removing ethanol. However, because the octane stripping is incomplete, the fuels octane level has been documented to drop only 1-1.5 units. (About 2.8 units of the E-10 octane rating is due to 10-percent ethanol addition.)
How long does it take for a half full tank to become saturated?
A half-full tank will become moisture saturated within 30 to 90 days, depending upon the temperature range and humidity. (Unless there is a leak, MTBE can collect water only from condensation, which is usually caught by a fuel/water separator.)
What is the solubility of water in E-10?
In E-10, the solubility of water decreases with temperature-0.6 percent is soluble at 85 degrees, but only 0.4 percent at 32 degrees-and when the solubility drops due to cooling, a portion of the water drops out of suspension, along with six times its volume in ethanol.
Why is E15 fuel not recommended for boats?
The approval of E15 fuel is putting boaters who fuel up at retail locations at risk because biofuels ARE NOT recommended for use in boats of any kind. One mistake at the gas pump can be a source of expensive, warranty voiding repairs and dangerous engine failure.
When is the deadline for comments on the fuel for marine engines?
The deadline for public comments is July 11. Take a minute and leave a comment to help protect the future of fuel for marine engines. Fueling is an important part of any trip to the lake. Don’t let misfueling bring your weekend plans to a halt. Check your tanks, check the pumps, and enjoy the lake!
Why do boats need to fuel up?
Here’s one reason why. The federal ethanol mandates require increasing amounts of biofuels—including corn ethanol—to be blended into the US fuel supply every year, such as E15 fuel. The approval of E15 fuel is putting boaters who fuel up at retail locations at risk because biofuels ARE NOT recommended for use in boats of any kind. One mistake at the gas pump can be a source of expensive, warranty voiding repairs and dangerous engine failure. Here are a few things to keep in mind the next time you hit the pumps.
What are the exemptions for ethanol?
A few exemptions to the standard allow gasoline without ethanol to be sold: 1 - When ethanol blends purchased at wholesale exceed the price of gasoline 2 - When selling premium unleaded gasoline with an octane rating of 91 or higher 3 - Gasoline sold at airports 4 - Gasoline sold at marinas
What does E10 mean in gasoline?
Three of the most common types of gasoline currently found on the market are E0, E10, and E15. The “E” stands for Ethanol and the number represents the percentage of ethanol in unleaded gas.
What to do if you find water in your fuel tank?
If you discover water in your fuel tank, pump the tank until it is dry. When you remove the fuel, place it in a clear container for inspection. If the fuel is not clear or has a bad or sour odor, you need to clean the tank. - Add a quality cleanerthat will help clean deposits in the engine.
Does ethanol burn water?
Gasoline with ethanol can absorb roughly 10 times as much water and still burn through the engine. However, when water comes in contact with ethanol blended fuel, the fuel and water can separate to form distinct layers in your tank. The upper “gasoline” layer will be depleted of ethanol and have a reduced octane level.
