What Are Fuel Additives for Gasoline Engines?

Fuel additives are components that, when added to gasoline, improve its quality: they prevent carbon buildup, remove water, and increase the octane number.

When using additives from trusted brands, you may notice reduced repair costs at the auto shop. These chemical compounds are designed to enhance engine performance—reducing noise, making exhaust emissions safer, and saving fuel.

It’s important to note that most additives work primarily as preventive measures.

Important! If you use additives to address an existing problem, the result may be the opposite of what you want. For example, a cleaning additive could clog fuel injectors with carbon deposits.

For the desired effect, it’s recommended to add additives when the fuel tank is 5–20% full. In this proportion, they mix better with the fuel, and engine power increases faster.

Types of Additives

All automotive chemicals in this category are divided into:

- Cleaning additives,

- Drying additives,

- Octane boosters,

- Universal additives.

The latter can replace several specialized products.

Cleaning Additives

These additives soften the deposits that form on valves, injectors, and engine pistons. Layer by layer, these coke-like deposits are removed, broken down, and expelled from the engine system.

Cleaning additives are further divided into:

1. Additives for the entire system,
2. Injector cleaners,
3. Combustion chamber and valve cleaners,
4. Carburetor cleaners.

Injector cleaner removes carbon deposits from fuel injectors, speeds up engine starts, improves dynamics, and restores full engine power.

Combustion chamber and valve cleaner quickly removes varnish and resin deposits. It activates at low intake temperatures and high combustion chamber temperatures. These additives work most effectively in cars with multiport fuel injection.

Carburetor cleaner removes carbon deposits from the moving parts of the carburetor.

Drying Additives

You’ll likely need these additives in winter. They remove water from gasoline, which enters the combustion chamber as condensation. If the moisture freezes, it can damage fuel lines or the filter mesh.

The additive protects engine parts from corrosion and maintains the car’s high performance.

Such additives consist of 80–90% alcohol. They work as follows:

1. The alcohol binds with water. The mixture’s consistency is similar to fuel and does not freeze.
2. While the car is running, the alcohol solution mixes with the fuel.
3. The water and alcohol burn in the engine cylinders.

Keep in mind that additives cannot remove already formed ice. If there was no drying additive in the gasoline and condensation has already formed, you’ll need to replace the fuel.

Octane Boosters

These additives change the proportion of key components in the fuel. As a result, the octane number increases by up to 10%, boosting engine power.

However, excessively increasing the octane number can damage seals and reduce the engine’s lifespan. Therefore, consult a specialist before purchasing such an additive.

Universal Additives

These additives combine the properties of cleaning, drying, and octane-boosting additives.

In some cases, a universal additive is the best option. For example, a carburetor cleaning additive should always function as a dryer.

We do not recommend using multifunctional additives in high-mileage engines. Overly active additives can clog all filters.

However, such additives are an excellent choice for new cars in good technical condition.

Hyper Auto Additives Overview

We offer specialized additives designed to solve specific problems, as well as multi-purpose products that ensure high efficiency.

This allows you to save on car chemicals.

How Do Multi-Purpose Additives Work for Gasoline Engines?

1. Increase the octane rating;
2. Protect the engine from condensation;
3. Remove deposits from the injectors, exhaust valves, and the entire fuel system.

The Carburetor Cleaner removes deposits from jets and fuel channels. We recommend purchasing it if you own a high-mileage vehicle.

The Injector Cleaner is designed to combat carbon buildup on valves and in combustion chambers. Regular use of this additive helps extend the lifespan of the fuel injection system.

Express Decarbonizer gently and effectively removes carbon deposits from pistons, compression rings, and oil control rings.

The Moisture Neutralizer quickly removes water molecules from gasoline. We recommend using this additive from November to March, especially during sudden temperature drops.

Fuel System Cleaner dissolves deposits and carbon buildup in fuel lines, valves, pumps, and injectors.

Oil System Cleaner extends the life of engine oil. We recommend adding it to the engine during every oil change.

Cooling System Cleaner removes scale, grease buildup, rust, and other contaminants.

By adding Hyper Auto fuel additives, your engine power will increase, its lifespan will extend, and you will save money on fuel and repairs. Additionally, your car will start easily in any frost.

How to Choose an Additive

The best way is to follow the recommendations of your car manufacturer or its official dealer.

The additive must be fully compatible with the materials used in your engine. This prevents breakdowns and ensures optimal performance.

It is also important to match the additive to your engine type. Ignoring this rule may lead to vehicle failure.

A professional consultation with a mechanic or a gas station specialist can also be helpful. They can advise you on the most suitable additive for your engine.

How to Use an Additive

Typically, additives should be added every 2,000–5,000 kilometers.

1. Shake the additive canister well for 10 minutes.
2. Pour it directly into the fuel tank or an empty canister. For first-time use, we recommend adding half the canister.
3. Fill up with gasoline, ensuring the exact ratio specified on the canister.
4. Drive as usual without refueling until at least half of the fuel tank is used up.

🚫 Never mix two or more additives at once! This "cocktail" will have little to no effect.

🛑 Before using additives, wear protective gloves, a mask, and safety glasses.
