Understanding through oil brands comparison

Brand History

As mentioned, Liqui Moly and Castrol are prominent in the industry. Their proven and verified quality products are mirrored in their available oils, like the Castrol edge vs Liqui Moly molygen.


It’s no surprise that every car owner has used their products since both brands have been in the industry for a long time. Apparently, both brands started their journey by supplying oil for planes. Castrol started in 1919, while Liqui Moly began in 1957.

1. Liqui Moly history


Liquid Moly has found its way into the industry during the war era. Most war planes survived and successfully landed due to the lubricant oil they used, Liqui Moly. It contains molybdenum disulfide or MoS2, the star ingredient for automotive products.

Hans Henle acquired and patented the product, hence the birth of the Liqui Moly brand.

2. Castrol history


Meanwhile, the Castrol brand began its journey in the automotive industry before Liqui Moly. During its initial years, its founder Charles Wakefield declared the future of the brand. That’s the person who made Castrol oil prominent.

Throughout the production process, their aim to produce lubricants for planes and automobiles succeeded. Their experiment using castor oil helped lubricants to work in a versatile mode, thus, forming a trustworthy product and brand called Castrol.

Product Differences

A little bit of comparison for both brands has been presented above. However, there’s much more to uncover from those ideas and more to present.

1. Base


The known base or type of oil for Liqui Moly and Castrol is synthetic. However, they don’t use the same kind of synthetic oil. Castrol oil types include PAO, while Liqui Moly oil is an ester.

PAO or polyalphaolefins is what is usually accepted for BMWs. It belongs to the Group IV category for synthetic oils. That’s because of its capability to withstand low and high temperatures.

On the other hand, Ester is also an invincible oil that can perform despite declining and increasing temperatures. The only difference is it belongs to Group V of the synthetic oil category. Group V is known as an aid to improve other base oils.

2. Temperature performance


As mentioned, both brands can produce versatile oils, which can perform well in a wide range of temperatures. Finding engine oil that can last is a big deal, especially if the weather is the outside factor. In short, it should be versatile enough to offer lubrication.

Since Castrol can manage up to 150°C, it will be perfect for traveling. The engine will not lack its lubrication even if it’s in use for a longer time. On the contrary, Liquid Moly can work even at -20°C. In short, it is better during the cold season than Castrol.

3. Viscosity


Regarding the temperature, engine oil viscosity is also different for both brands. Viscosity involves the thickness of the engine oil and how it affects the flow of lubrication for the engine.

Car owners must have compared one of the most common viscosity grades both brands offer. Choosing between the Castrol 5w30 vs Liqui Moly 5w30 can be tough as both offer protection and lubrication.

However, if versatility is the topic, Castrol might offer more deals than Liqui Moly. Castrol offers various viscosity grades that vehicle users can use during the winter. Not only the 5w30 (Castrol edge 5w30), but the brand also has 0w20 until 0w40.

4. Liqui Moly Additives vs Castrol Additives


Additives in engine oil are the formula that ensures protection for the engine. That involves factors that help keep the machine running smoothly despite numerous factors (e.g., corrosion, sludge, etc.).

So, is Liqui Moly oil good?

Regarding additives, Liqui Moly is a premium oil brand offering ceramic oil treatment. This additive prevents heat buildup and severe friction during engine usage. Thus, ensuring the safety of the driver and keeping the car functional.

 So, is Castrol oil good?

Meanwhile, Castrol oil also provides many additives to protect the engine from further damage. It includes a detergent additive, which helps dispersant additives to keep the engine clean from particles.

Other vital additives are present in Castrol, one of which is anti-oxidants. Unfortunately, Liqui Moly may seem to fail this comparison due to the lesser additives included. Despite that, it is still a strong contender against Castrol.

5. Price

When it comes to the price list, it can be concluded that Liqui Moly offers a higher range than Castrol. That can be shown in the product comparison Liqui Moly 10w60 vs Castrol 10w40. Of course, the product is a must-try, especially for sports cars.

Meanwhile, Castrol engine oil 10w40, like CASTROL GTX HIGH MILEAGE 10W-40, is also a great product. It is also 100% synthetic like the counterpart but is available at a lower price.

In short, both brands and products are highly effective. It will now depend on whether the buyer wants the expensive or cheaper version.

6. Compatibility


Aside from understanding the similarities and differences between these prominent brands, it is equally important to know their compatibility with people’s cars. Luckily, both are highly functional and offer 100% synthetic quality, which BMW cars need.

Finding suitable engine oil has never been easier for this car brand. Ensuring functionality and ease of use, like their best car model, e46 m3, is the priority when choosing a suitable engine oil.

Since it involves the welfare of the engine, car owners must choose wisely when selecting the product. But, according to Catstrol and Liqui Moly, compatibility is ensured.
