Overview of Castrol

The advanced full synthetic Castrol Edge oil has different configurations from 0W-20/40. So you have multiple options to choose any of this viscosity-graded oil based on your vehicle recommendation and the weather condition. 

The high-temperature resistance of the oil will ensure smooth flowing into the engine. The better oil flowing penetrates the engine’s parts to avoid metal engagement, consumes less fuel, and offers heavy mileage performance. 


  • Ensure quality with good detergent additives 
  • One oil is the solution for most types of engines
  • Reduce engine starting vibration and noise generation 
  • Unbeatable price than other engine oils 

A Detail Comparison of Liqui Moly vs. Castrol

Well, after reading the overview about Liqui Moly and Castrol motor oils, you might think they are occasionally interchangeably usable. That’s slightly right. In some cases, you can interchange them, but in severe cases, it’s not wise. 

So, let’s learn an in-depth analysis of these motor oils to determine which is better in which cases.  

1. Quality And Formulation

Quality always matters when choosing engine oil because it can offer the engine’s best performance with long life. The poor oil fails to offer maximum performance and damages the engine. 

Liqui Moly

Leading car magazines in Germany publish a reader’s poll. Liqui Moly repeatedly gets top marks from its authentic users as an appreciation for providing quality oil. 


The Castrol oil meets American Petroleum Institute (API) and European Automobile Manufacturers Association ACEA A3/B4 standard recommendations. Not only that, some other standards that Castrol oil meets are Mercedes Benz 229, Ford WSS-M2C937-A, and Porsche A40. So you can trust this oil for its quality. 

2. Viscosity Level 

The engine oil viscosity defines how thick or thin the oil is! The more the oil thickness, the better it can perform under high pressure without breaking down. On the other hand, the lower the viscosity, the quicker it’ll break down. 

Liqui Moly

The 5W-40 viscosity of the Liqui Moly oil is excellent to use from -25°c to 35°c temperature. You can also easily filter the oil, because it gets sticky faster than Castrol oil. So, you must frequently change the oil, which is irritating for longer driving. 

The Castrol 

This oil comes with better thickness and won’t get sticky within running a few miles. So, you get three different advantages than Liqui Moly oil. These are; less oil consumption for running the same miles, fewer emissions are released, which causes less environmental pollution, and your fuel cost will be lower. 

3. Functionality

Engine oil has to perform different types of functionality in the different parts of the engine. So, the oil which functions well from all sides is the best compatible oil for your engines. We discuss the oil’s functionality in smooth lubrication, heat resistance, pressure handling, and engine protection.

Liqui Moly

Though Liqui Moly gets users appreciation for its quality, comparing its flowing time and engine optimization ability under tough weather, especially in high temperatures, it won’t be as good as Castrol oil. 

Even the Liqui Moly oil can’t keep the oil clean longer to offer you high mileage professional performance compared to Castrol. 


It is a gem for all types of engines to offer you superior engine protection, excellent deposits prevention, and incredible oxidation resistance. In a word, all of these boost up the engine to lengthen its lifespan. 

Moreover, the oil can handle the high temperature. So you won’t have to worry about your local weather condition when running the engine for many hours at a stretch. 

4. Oil Changing Interval 

Oil changing interval also reflects the engine efficiency and how many miles it can run with the oil. The longer the oil changing interval, the better its mileage, and vice versa. 

Liqui Moly

You must change the Liqui Moly oil after every 5000 miles of running. This means it can offer you a medium mileage range. However, the oil changing interval may be lower than this mileage due to your harsh and inexperienced driving. Because of this driving, the oil will turn black and gunk before reaching its recommended mileage. 


On the other hand, Castrol oil offers you at least 10000 mileage of efficient running with one oil filling. As a result, you can frequently avoid oil-changing hassles when using this oil. 

5. Oil Changing Cost

You must spend some bucks every time you change your engine oil. So it would help if you also considered oil change cost to determine whether one oil is better than another.

Liqui Moly

Since Liqui Moly is slightly expensive and offers lower mileage than Castrol oil, you must put this oil into your engine two times to run the same engine mileage as Castrol oil. So your oil changing cost for this oil will be approximately $90. 


Pocket-friendly price and high mileage performance will lower your Castrol oil changing cost. You may need to spend around $25 for an oil change.

Is Liquid Moly better than OEM?

No, Liqui Moly isn’t better than OEM. The manufacturer knows their engine well and keeps in mind all those things when it formulates OEM oil. But, since the Liqui Moly oils passed most OEM specifications, you can confidently use them if it permits your budget and weather. 

What To Choose Between Liqui Moly Vs. Castrol

It’s very difficult to announce the winner between Liqui Moly vs. Castrol motor oil. Generally, you have to know your vehicle’s recommended oil, budget, and local temperature ranges to define what will be better for you. 

However, you can go with Liqui Moly oil for its superior protection, performance, and peace of mind. 

Contrastly, you should choose the Castrol oil for your light cars, trucks, and motorcycles. 

No matter what oil you choose, keep in mind safe driving!
