Modern additives for classic cars provide the solutions needed for adding power and a longer engine life. Indeed, the fuel additive market is exploding, thanks to an increased interest from classic car owners.

Modern Additives for Classic Cars

Potent Blends

Today, turbo octane boosters can transform top quality fuels into potent blends. In fact, the solutions can cause the fuel to perform almost as well as race car gas. Modern additives for classic cars include the following:

  • Lead replacement additives
  • Solutions that safeguard the engine from ethanol
  • Corrosion inhibitors
  • Competition valve-type lubricants

Keeping the Engine Safe

Modern additives that protect older cars from ethanol are important formulations. These  solutions keep the engine safe from excessive condensation, rust, and erosion. Any fuel additive for a classic car then must be ethanol-compatible.

Some classic cars are designed to accept lead gasoline. So, when using unleaded gas, car owners must use lead replacements. Using the replacements prevents valve seat recession as well.

Protection against Corrosion

However, ethanol corrosion is the main reason for additive use. Therefore, modern additives include solutions that inhibit the activity. Additives of this type protect the tubes, tanks and engine gaskets against rust.

Fuel Phase Separation

What additives you use depends on a car’s age and design. For example, an older car with a carburetor can suffer ethanol damage. Therefore, drivers should seek fuel additives with carburetor safeguards. These kinds of products stop fuel phase separation and damage.

A Hygroscopic Product

Ethanol causes problems because it is hygroscopic. Fuel tank condensation is the result. When fuel systems contain water, fuel phase separation or water contamination occurs. If a separated or contaminated fuel travels into the engine, it can stop running.

Protecting an Engine from Ethanol

Besides being corrosive, ethanol also disintegrates plastic, rubber, or fiberglass. Happily, there are ways to handle an ethanol problem. Besides using the proper additives, you should use nylon tubing or fuel lines instead of rubber or plastic. Also, replace a fiberglass fuel tank with a stainless steel tank. Changing out the O-rings can help too.

For an additive, use a non-alcohol based fuel treatment. This type of solution will prevent additional water accumulation in the gas. Never use an ethanol-based fuel treatment when you are using an ethanol-based gas.

Featured Additives

Additives comes in a variety of formulas. The following list presents the main products.

–Fuel stabilizers maintain gas efficiency during  the times a car is not used. The stabilizers prevent the hard starts that result from engine corrosion. Troubles with starting typically occur when the gas separates.

–Octane boosters increase the octane rating of a fuel. They protect an auto’s cast-iron valve seats with a lubricant base.

–Fuel injector cleaners protect fuel injectors against ethanol build-up. Without the use of the cleaners, injectors clog up.

–Anti-gel diesel additives  unclog diesel fuel filters. They prevent hard-starting problems during low temperatures.

Fuel additives that contain polybutene amine, or PBA, can be invaluable. They are ideal for cleaning build-up from fuel injectors, intake valves and carburetors.

In order to select a modern additive, you need to read the directions for the product. You also should talk to a mechanic about your power needs. Additives can save you both time and money if they are used properly. However, do not use an additive without confirming its use. Different cars require different products. Therefore, check to make sure that the additives you are using can enhance your car’s performance. Again, talk to a mechanic if you are unsure about your choices.
