What Is Air Cooled Engines?

What Is Air Cooled Engines

To cool down the engine, Air-cooled engines do direct air circulation over heat dissipation fins or hot areas of the engine. By doing air circulation, it maintains the engine’s operating temperature.

Air cooling systems are generally used in which liquid cooling systems aren’t suited. For example, Motorcycles, lawnmowers, generators, and outboard motors all come with air-cooled engines.

In contrast to a liquid-cooled engine, air-cooled engines are more affordable, fuel-efficient, and take lesser engine spaces. Moreover, the maintenance cost of the air cooled engines is quite less than that of water-cooled engines.

What Oil Is Best For Air Cooled Engines?

What Oil Is Best For Air Cooled Engines

For automobiles, synthetic or semi-synthetic oils are good for engine health. This is also true for the ail cooled engine. However,  some commercial motor oils meet the purpose if we select the right oil according to the oil’s configuration.

Now let’s talk about the motor oil configuration and see what is the best air cooled engine oil. Motor oils come in SAE xW-X, for instance, SAE 5W-30, 10W-40, 15W-50, and so on. Which number would be perfect for air cooled engine mainly depends on the operating temperature and outside weather.

Generally, you can go with an SAE 10w-40 to 10W-50 for moderate weather. For cool weather, you must choose 5W-30 or 10W-40 for air cooled engine. Therefore, you can go with an SAE 10W-40 motor oil for air cooled engines regardless of the weather conditions.

Buying Guides: Best Oil For Air Cooled Engines

Best Oil For Air Cooled Engines

As you know, Air-cooled engines always demand a particular motor oil. And there are some issues which are associated with the engine oil that should be considered before the best oil for small air cooled engines.

If you are getting tensed about what to buy, then take a look at the following factors, which will guide you toward the right king of moto oil.

Oil Configuration

When you come across a motor oil, you will see some letters and numeric digits on the label. What actually does it means? For example, SAE 10W-20, here w means winter, and the digit 10 is indicating the oil viscosity in cold temperature. The lower the number, the oil viscosity will be thin in the cold temperature. Like 5W, or 0W would be chosen for the extremely cold temperature.

On the other hand, 20 refers to the oil viscosity at a high temperature. The higher the number, the oil viscosity would be thin in the high temperature.

In a word, you can go with between 15W to 20W for a moderate climate and 30-50 for high temperatures when you choose air-cooled engine oils.

Oil Types

There are different varieties of engine oil found in the market, such as conventional oil, semi-synthetic oil, or full synthetic oil. Now the question is which one should buy, isn’t it?

Conventional Oil

It is made of refined crude oil. The cost of the oil is much lesser than synthetic or semi-synthetic oil. And not 100% reliable for long-lasting engine performance.

Semi-Synthetic Oil

It is made through a blend of conventional oil and some man-made lubricants. More reliable than conventional oils. However, It is less effective than full synthetic oil, and the cost is almost half of synthetic oil.

Synthetic Oil

It is a lab-produced oil with some useful additives for motor engines. It contains lots of micro-elements that help to keep your engine in tip-top condition. Thus, it considers the most reliable motor oil. However, the price of the oil is skyrocketed than the other oils.

Anti-wear Protection

If the motor oil doesn’t work for anti-wearing, then what is the point of having such oil, right? Not all engine oils provide the same level of wearing protection. The oil can provides maximum anti-wear protection, that has maximum beneficiary contents like zinc, phosphorus, and so on.

Therefore, you must be aware of the anti-wear properties of the oil before buying.
