Learn About Air Cooled Motorcycles
Before learning about air cooled motorcycle oil, learn about air-cooled motorcycles.
Whether you’re a new motorcycle owner or a seasoned pro, the more you learn about your bike’s engine the better equipped you will be to take care of it.
Regardless of how many miles you’ve put on your motorcycle, differences in engine design offer an opportunity for the owner to fine-tune their bike’s performance.
This all begins with maintenance, like regular air cooled motorcycle oil changes using a high-quality synthetic motor oil!
In this article, we will talk about the different kinds of engine cooling as well as which oil is best for air-cooled motorcycle oil or liquid-cooled engines.
What Is an Air Cooled Engine?
Air-cooling is pretty much as simple as it sounds.
This method of cooling the engine relies on air moving over the engine as it moves down the road.
This is often encouraged by fins affixed to the exterior of the engine, which increase the surface area and encourage better cooling potential.
This tried-and-true method of engine cooling has been used for decades thanks to its simplicity and the fact that it does not require a lot of extra weight.
If you’ve ever seen a motorcycle with fins on the engine, this is why!
In some models of motorcycles or motorized scooters, forced air cooling is employed.
This method involves an engine-powered fan that distributes air over the internal engine body as well as over the exterior fins.
What Is a Liquid-Cooled Engine?
The other kind of engine cooling method requires a water-based solution, which contains an alcohol-based coolant.
This ingredient prevents the liquid from freezing or rusting as it travels from place to place on an engine.
This type of engine cooling is considered more complex than air cooling, as it requires the addition of a radiator and more pipes.
While liquid-cooled engines do have more of a capacity to break and “go wrong” just by merit of having more parts to maintain, they do offer some benefits to offset this.
One such benefit is a reduction in engine vibration, which means better efficiency as well as less mechanical noise.
Another benefit is the liquid cooling system helps keep the engine at a regular temperature regardless of the temperature outside.
This increases your engine’s adaptability and stabilizes the performance in a wider range of possible weather scenarios.
So, Which Motor Oil Is Best?
While air-cooling and liquid cooling are both ultimately effective, one is not necessarily better than the other.
Some people like the louder operating volume of an air-cooled motorcycle, and don’t want to mess around with a radiator.
Others prefer to do their riding in all kinds of climates and prefer the stability that comes with a liquid-cooled engine.
Regardless of your personal preference, knowing how your engine cools is important to its overall maintenance.
So, which motor oil is best for an air-cooled engine? How about a liquid-cooled engine?

Air cooled motorcycle engines
Air-cooled motorcycle engines are a type of engine design commonly found in motorcycles, particularly older or classic models.
Unlike liquid-cooled engines that use a radiator and coolant to regulate temperature, air-cooled engines rely on natural airflow to dissipate heat and maintain operating temperatures.
The primary characteristic of an air-cooled engine is the presence of cooling fins on the engine cylinders and heads.
These fins increase the surface area of the engine, allowing heat to be efficiently dispersed into the surrounding air.
As the motorcycle moves forward, air passes over the cooling fins, carrying away the heat generated during combustion.
One advantage of air-cooled engines is their simplicity and reduced complexity compared to liquid-cooled engines.
They have fewer components, such as radiators and coolant hoses, which can be prone to leaks or failures.
Air-cooled engines also tend to be lighter and more compact, contributing to the overall weight savings of the motorcycle.
However, air-cooled engines have some considerations regarding their operation and maintenance.
Due to their reliance on airflow for cooling, these engines can be more susceptible to overheating, especially in hot weather or during prolonged periods of idling or slow-speed riding.
It is essential to monitor engine temperatures and avoid prolonged idling to prevent overheating and potential engine damage.
Regular maintenance is crucial for air-cooled engines to ensure their optimal performance and longevity.
Here are some key maintenance aspects for air-cooled motorcycle engines:
Cooling System: Inspect the cooling fins regularly and ensure they are free from dirt, debris, or blockages that can impede airflow.
Clean them gently using a soft brush or compressed air if necessary.
Oil Changes: Regularly change the engine oil according to the manufacturer’s recommendations.
Clean oil helps lubricate and cool the engine components, reducing friction and heat buildup.
Spark Plugs: Check and replace spark plugs as needed. Properly functioning spark plugs contribute to efficient combustion and prevent overheating.
Air Filter: Clean or replace the air filter regularly to ensure proper airflow to the engine. A clogged air filter restricts air intake and can lead to overheating.
Ignition Timing: Periodically check and adjust the ignition timing to maintain optimal engine performance.
Correct ignition timing helps prevent overheating and ensures efficient combustion.
Riding Practices: Avoid excessive idling or prolonged periods of slow-speed riding, as these conditions can limit airflow and lead to overheating.
Instead, maintain a steady speed or take short breaks to allow the engine to cool down if necessary.
By following these maintenance practices and staying attentive to the engine’s temperature, air-cooled motorcycle engines can provide reliable performance and longevity.
Remember to consult your motorcycle’s owner’s manual for specific maintenance guidelines provided by the manufacturer, as different models may have unique requirements.
Q. What is the best engine oil for air-cooled motorcycles?
A. The best engine oil for air-cooled motorcycles is typically a high-quality, synthetic oil that is formulated specifically for motorcycles with air-cooled engines. These oils are designed to provide superior heat resistance and excellent lubrication, which is crucial for maintaining optimal performance and protecting the engine components. It is recommended to choose an oil that meets the viscosity and performance requirements specified by the motorcycle manufacturer.
Q. Do air-cooled engines need special oil?
A. While air-cooled engines do not necessarily require special oil, it is highly recommended to use oil that is suitable for air-cooled applications. Air-cooled engines tend to operate at higher temperatures compared to liquid-cooled engines, so using oil with the right viscosity and additives can help manage heat and provide adequate lubrication. Motorcycle-specific oils, particularly those formulated for air-cooled engines, often offer enhanced thermal stability and protection against high-temperature wear.
Q. Can I use 2-cycle oil for air-cooled engines?
A. No, it is not recommended to use 2-cycle oil in air-cooled engines. 2-cycle oil is specifically formulated for use in engines that require a fuel-oil mixture, such as small two-stroke engines found in certain power equipment like chainsaws or leaf blowers. Air-cooled motorcycle engines typically use separate oil and fuel systems, requiring dedicated engine oil that meets the manufacturer's specifications.
Q. Do air-cooled engines use oil?
A. Yes, air-cooled engines, including those in motorcycles, require oil for lubrication and cooling purposes. Oil plays a critical role in reducing friction between moving engine components, preventing wear, and carrying away heat from the engine. It is important to regularly check the oil level and perform oil changes at the recommended intervals to ensure proper lubrication and cooling of the air-cooled engine.
