Additives

Additives for motorcycles are products designed to improve engine performance, extend the service life of mechanical components and optimise fuel combustion. Many riders wonder whether they are really useful and how to use them correctly.

Why use motorcycle additives?

Motorcycle additives have several essential functions. Some improve engine efficiency by reducing carbon deposits and optimising fuel combustion, which can lead to lower fuel consumption and increased performance.

Others protect mechanical components against premature wear by reducing friction and promoting better lubrication. Additives are also useful to prevent fouling of the injection system and the carburettor, a common issue on bikes used in urban environments or for short trips.

What are the different types of motorcycle additives?

There are several categories of additives, each with a specific action.

Fuel additives help improve the octane rating of petrol, clean the fuel system and prevent the build-up of harmful deposits in injectors or the carburettor. Some products are specifically formulated for 2-stroke engines, others for 4-stroke engines.

Engine oil additives enhance the lubricating properties of the engine oil by reducing friction and wear on moving parts. They are particularly recommended for high-displacement motorcycles or bikes used in extreme conditions (racing, high temperatures, long distances).

Engine cleaners and decarbonisers remove combustion residues that accumulate in the combustion chamber and on the valves. A dirty engine can lose power and consume more fuel. These additives provide internal engine cleaning and can restore original performance.

Finally, cooling system additives protect the radiator and cooling circuit against corrosion, scale and overheating. They help maintain an optimal operating temperature, which is crucial to avoid engine overheating.

How and when should you use motorcycle additives?

The use of additives depends on the type of product and the specific needs of your motorcycle. For fuel additives, it is recommended to pour them directly into the tank before filling up, to ensure proper mixing with the petrol. Depending on the product, regular or occasional use may be recommended. For example, an injector cleaner can be used every 3,000 to 5,000 km, while an octane booster can be added before a ride where higher performance is required.

Engine oil additives must be added during an oil change or when checking the oil level. It is important to follow the dosages specified by the manufacturer to avoid overdosing, which could alter the properties of the oil.

Engine cleaners are often used before an oil change, to remove residues and impurities present in the system. Proper internal cleaning helps preserve engine longevity and optimise its efficiency.

As for cooling system additives, they can be added directly to the coolant. They are recommended when the coolant is replaced or as a preventive measure, especially before periods of high temperatures or long journeys.

Are motorcycle additives really effective?

The effectiveness of additives depends on several factors, including product quality, the overall condition of the motorcycle and how often they are used. An engine that is well maintained with quality engine oil and clean fuel will require fewer additives than an engine subjected to harsh conditions. However, when used correctly and as a complement to regular maintenance, additives can extend engine life, improve performance and reduce fuel consumption.

Before using an additive, it is advisable to consult your motorcycle’s owner’s manual and choose a product suited to your engine. Some manufacturers advise against the use of certain additives that could affect engine operation or injection systems. Choosing well-known brands such as Motul or Bardahl and following the manufacturer’s recommendations are essential precautions to avoid any issues.

In summary, motorcycle additives are not strictly essential, but they can be a valuable asset to keep an engine clean, efficient and durable. Depending on your needs, they help improve combustion, protect mechanical parts and optimise the overall operation of your machine.
