What is a Fuel Stabilizer? How Does it Work?

They are products that preserve stored fuel. Regardless of the type, if it isn’t being used, it won’t last indefinitely. Over time, the chemical structure will change. This applies to all fuels derived from fossil fuel, including diesel, gasoline, kerosene, etc.

Once the composition of fuel is altered, it won’t have the same properties. In a practical sense, once such aged fuel is in your car, your engine won’t run the same way. In fact, it may not work at all.

The fuel in this altered state can also cause damage to the internal workings of the engine. Old gasoline can form solid gum-like deposits. The same is true of diesels. These can clog up the internal workings of the entire engine.

At this point, you may be wondering how fuel can go bad? After all, crude oil has lasted for millions of years.

The answer is that crude oil goes through a refining process to produce petroleum products that we used today. These range from waxes (such as petroleum jelly) to heating oil and of course, engine fuel. The final products bear little resemblance to the original fossil fuel.

Most of the gasoline sold in the United States is mixed with ethanol. The ethanol works to lower the toxic emissions produced by gasoline-run engines.

Ethanol can separate from gasoline if left unused for long enough. This is known as phase separation. When gasoline is exposed to water, the separation speeds up.

This alcohol may be useful when mixed with gasoline, but can be corrosive by itself. Ethanol also causes gasoline to evaporate faster, especially under warmer conditions.

Diesel and biodiesel—non-petroleum based diesel fuel can also degrade with time. The same applies to mixtures of the two, diesel and biodiesel.

Fuel stabilizers are made from substances that prevent or slow these chemical changes. Some brands claim to be capable of restoring old fuel as well as preventing new degradation.

A common ingredient is hydrotreated light napthenic distillate. It also goes under the names of mineral oil or petroleum distillate, although these terms are broad. Gasoline, for example, is also a petroleum distillate, as are most petroleum products.

Methanol is another conventional fuel stabilizer. It promotes smoother burning and cleaner combustion.

Another benefit is that methanol reduces the risk of corrosion. When mixed with other alcohols, it can combat phase separation in ethanol-based gasoline.

Fuel stabilizers can also contain detergents or conditioning agents. The detergents work to break down gummed up fuel to prevent blockages. Conditioning agents can be things like lubricants, which improve engine function.

Certain brands of stabilizer are made with secret ingredients. In these cases, only the manufacturer knows the exact formula.

How Long is Too Long to Store Fuel?

There is no simple answer to the question of a fuel’s shelf life. Environmental factors can hasten it’s expiration date. This can include exposure to oxygen, heat, and humidity.

Fuel stored in appropriate storage containers will keep for longer. When it’s in a tank (like in your vehicle) it is exposed to the elements, specifically air.

For gasoline, it’s recommended to use it within a month of purchase. If you store it in an airtight can, you can extend the shelf life to six months.

Note that the storage container should have space for the gasoline to expand. It should also be smaller than five gallons.

For diesel, the lifespan in storage is 12 months, if the temperature is below 68 degrees Fahrenheit. At 86 degrees Fahrenheit or higher, you can expect diesel to stay viable for six to 12 months.

Remember this only applies to fuel storage containers, not the tank in your vehicle or equipment. Exposure to metals of all sorts will speed up diesel deterioration.

This is an important point to reiterate. Forgetting about fuel that’s been stored too long in your vehicle can do irreparable damage to your engine and equipment. If you try to run the motor, you’ll be distributing buildup gunk throughout the engine system.

Also, if you do have old gas that needs throwing away, make sure you dispose of old gas properly and responsibly!

Can a Stabilizer Reverse Bad Fuel?

Some stabilizers on the market are capable of reversing changes in fuel that has been stored for years. The exact ingredients of these types of miracle stabilizers are trademark secrets, though.

The worse off the fuel’s condition, the less likely it is that a stabilizer will help. It’s preferable to avoid fuel from aging to that point in the first place.

Bear in mind that running rancid fuel can cause blockages or destroy your engine. You don’t want to make forgetting about stored fuel a habit.

How to Choose the Best Fuel Stabilizer – Buying Guide

There are a few things to consider before you pick a fuel stabilizer, as it’s important you choose the right product for the fuel you want to treat.

Gasoline, Diesel, or Oil Stabilizer?

Gasoline and diesel are distinct from one another. Diesel is denser than gasoline and has a higher boiling point. Gasoline is flammable, whereas diesel is combustible.

Similarly, diesel and gasoline engines run in different ways. You can’t use gasoline in a diesel engine, and vice versa. For these reasons, the oil we use to lubricate our engines is typically fuel-specific.

Your chosen stabilizer also has to be compatible with what you will be using it on. If you want to stabilize both diesel and gasoline, you can opt forone that works with both.

Using an incompatible stabilizer isn’t wise. At best, the wrong fuel additive won’t be effective. At worst, you might end up with engine damage or an unpleasant chemical reaction. Knowing which to buy will save you hassle as well as money.

Ease of Use and Mixing Instructions

Most brands of fuel stabilizer are straightforward to use. You won’t need to be proficient in mechanics or engineering.

All you have to do is pour the correct amount of stabilizer into the tank. This could be before or after you fill the tank, depending on the brand.

The instructions will tell you the right quantity for the amount of fuel you’re treating. You might have to let the product settle before you run the engine.

Having said that, some stabilizers are still easier to use than others. The containers may include spouts that make the stabilizer easier to measure out.

You’ll want to be sure to carefully read the intended use before purchase. For instance, not all fuel stabilizers are meant for refreshing old fuel. These variations should be used exclusively on fresh gasoline.

Any Compatibility Issues

Compatibility doesn’t only apply to the type of fuel you want to stabilize. Look at the product guidelines to see what sort of engines the stabilizer is rated for.

A few brands only work on either two-cycle or four-cycle engines. Others are developed for specific vehicles or equipment. For example, some are primarily intended for use in boats.

Reviews and Customer Satisfaction

Reviews can guide you in the right direction when you’re buying a fuel stabilizer. You can find out if a particular brand will meet your expectations based on the experiences of others. Search out reviews written by real people, like on Amazon.

The manufacturer’s website or product pamphlets can sometimes be biased. It’s always helpful to learn about the results that others have had with a particular product.

Price

The prices can vary dramatically. The ingredients, manufacturer, and concentration all play a role in the cost.

The quantity is often less important than concentration. A big bottle might treat less fuel than a small bottle if the smaller one has a highly concentrated formula. Compare costs based on how much fuel can be treated, not the actual size of the product.

Stabilizers from well-known companies are likely to be priced higher. At the same time, you’re usually getting a better quality guarantee than from a lesser known brand.

Best Fuel Stabilizers for Gasoline

Below, we’ve rounded up and added mini reviews of the best fuel stabilizers for gasoline for your convenience. There’s a stabilizer listed suitable for every type gasoline engine—so take a look to find the right one for you.

This concentrated product can be used for a range of applications. To start with, you can treat over 250 gallons of gasoline with a single 16-ounce bottle.

The stabilizer needs to be added before fill-up, and initial treatment needs 1 ounce for every 8 gallons. Subsequent refills only require half that amount.

Measuring this stabilizer out is easy, thanks to 1-ounce markings on the bottle. In the event that you accidentally pour too much in, there’s no need to panic. The ingredients are engine-friendly, and the excess product won’t cause damage or blockages.
