Comparison of Top Engine Oil Brands: Mobil 1, Castrol, Liqui Moly, Motul

Most drivers don’t know that the right engine oil can help in the smooth operation and longevity of their vehicle’s engine. And with several renowned engine oil brands dominating the market, each claiming to be the best, finding the right engine oil can be challenging. In this blog post, we’ll compare four leading engine oil brands: Mobil 1 Vs Castrol Vs Liqui Moly Vs Motul to help you make an informed decision for the best possible ride.

How to choose between Mobil 1 Vs Castrol Vs Liqui Moly Vs Motul?

Before we start choosing the best car and bike engine oil in India, we must first drill down on the importance of this vital lubrication fluid. Engine oil is contained in the oil sump or reservoir and pumped at pressure to all moving parts of the internal combustion engine. It mainly lubricates the valve train, pistons and cylinders, crankshaft, clutch and gears. Although some vehicles use a separate system to lubricate the

Let’s just say engine oil is the lifeblood of a vehicle’s engine, facilitating its operation and extending its longevity. Here’s why it’s indispensable:


Moving parts of the engine create a large amount of heat due to friction. Engine oil’s primary role is to reduce friction & wear. It does this by creating a thin film over moving parts that prevents metal-on-metal contact. Constant movement without engine oil will cause the part to fail, e.g. Pistons will seize or valves will get stuck.

Heat Dissipation:

Engine oil’s second role is to dissipate heat generated during engine operation. It absorbs and transfers heat away from critical components, sometimes sending it to an oil cooler radiator. The engine operates at optimal temperature with engine oil.

Seal Protection:

Many of the engine seals and gaskets need to be coated with oil to maintain their integrity. Rubber seals are prevented from drying out and cracking, especially under high heat conditions. The engine is properly sealed and free of leaks with the right oil flowing through it.


Engine oil contains detergents and special additives that can carry away dirt, debris, metal shavings and carbon deposit contaminants that accumulate in the engine. Engine oil is constantly cleaning the engine and keeping it free from harmful deposits. This is important for engine efficiency and extended lifespan.

Does Engine Oil Brand Make a Difference?

Now that we know the basics of engine oil, we are in a good position to decide on the brand. Engine oil can indeed make a significant difference in terms of driving quality, engine performance (and very often compatibility with your vehicle).

Here are some reasons why different brands are preferred by some manufacturers and drivers who are looking for something special from their vehicles.

Quality Assurance:

Established brands such as Mobil, Castrol, Motul, Liqui Moly, Wurth and Shell invest big time in research & development. They test their engine lubricants to ensure top quality and performance in all conditions. More importantly, they adhere to strict industry standards & regulations to deliver reliable products that drivers trust and manufacturers recommend.

Formulation Expertise:

Each brand of engine oil may use advanced formulations and additives that have been patented. They are tailored to specific engine types (petrol/diesel), desirable driving characteristics (high mileage and extended change intervals), and performance requirements (road or racing applications). Some vehicle manufacturers recommend specific brands or formulations based on these characteristics that make them well-suited for their engines. Engines are even designed with the engine oil in mind to ensure optimal performance and compatibility.

Long-Term Benefits:

High-quality engine oils from trusted brands offer long-term benefits as compared to affordable products that just do the job. With big brands, you may see improved fuel efficiency, extended engine life, and reduced maintenance costs by extending the change intervals and overall better engine health. Choosing a reputable brand can ultimately save you time and money during the lifetime of your vehicle.

While all engine oils serve the same fundamental purpose of lubrication, cleaning, heat dissipation and protection, each brand’s product can focus on certain aspects of performance, reliability, and overall driving satisfaction. Select a reputable brand that meets the specific requirements of your vehicle and one that can cater to your driving habits for optimal results.

Buying Engine Oil

How Often Should You Change Engine Oil?

When you change your engine at regular intervals as per manufacturers recommendation, it contributes to maintaining the health and performance of your vehicle’s engine. The frequency of oil changes varies depending on factors such as vehicle type, engine specifications, age, mileage and sometimes even driving conditions.

Here are some general guidelines on when to change the oil:

Manufacturer Recommendations: You need to check you service manual or ask your dealership / mechanic about oil change intervals. It’s the most reliable source because manufacturers typically provide specific guidelines for oil change intervals based on various factors.

Time or Mileage: Most modern vehicles require you to change the oil every 5,000 – 10,000 km or every 6 months. But, new vehicles equipped with synthetic oils have longer intervals, and can last beyond 10,000 km or up to a year before they need an oil change.

Driving Conditions: If you regularly drive in frequent stop-and-go traffic, tow heavy loads, or driving in extreme temperatures, off-road or take your vehicle to the track, that could accelerate oil degradation. Hence, more frequent oil changes are required for optimal engine protection and lubrication in tough conditions.

Oil Quality: The type of engine oil and brand used also play a role in determining when the oil needs to be replaced. Synthetic oils which have high thermal stability typically last longer than conventional oils which lose their viscosity sooner due to frequent heating and cooling cycles.

Checklist: Signs for an Oil Change
Dash indicator light that shows an oil can glowing or blinking
Increased engine noise or knocking sounds
Check engine light on instrument cluster
Dipstick with dark or dirty oil
Excessive exhaust smoke or a burning oil smell
Low oil level on the dipstick.
Mileage indicates that it is time for an oil change as per the service manual
Poor performance, slow acceleration and not able to reach top speed
Decreased fuel efficiency
More than a year since the last oil change

Consequences of Neglecting Oil Changes

Failing to change your oil at regular intervals can have damage your vehicle’s engine and hamper performance permanently. Here’s what can happen if you don’t change the oil when required:

Increased friction & wear of engine partsOil loses its lubricating properties over time. It leads to high friction and wear on engine components such as valves, pistons and cylinders. This can result in premature engine failure & costly repairs at the least. 
Deposit Build UpOil accumulates sludge, dirt, carbon, metal shavings and other contaminants while it runs through the engine. Eventually, it will clog oil passages and inhibit proper lubrication. The engine will overheat and fuel consumption will increase. 
Reduced Engine Acceleration and Low PerformanceIncreased heat and friction will prevent the engine from operating properly. This can result in poor engine performance and reduced power output as well as rough engine operation. 
Engine DamageCritical engine components such as pistons, bearings, valves and camshafts can suffer damage due to inadequate oil. They will wear prematurely. The entire engine may have to be replaced.
Decreased Life of EngineThe lifespan of an engine is largely determined by regular oil changes. Neglecting this process can shorten the engine’s lifespan.


Choosing the right engine oil is perhaps the most important part of maintaining the health and high performance of your car or bike’s engine. Of course how and where you drive also makes a difference, but if you have a good brand of engine oil, it should take care of most issues that could crop up with an inferior engine oil. While Mobil 1, Castrol, Liqui Moly & Motul all offer high-quality oils, each brand has a unique formula that gives it certain strengths and considerations in situations. Evaluate your vehicle’s needs, review your driving habits, and choose a budget to select the best oil for optimal performance & longevity of your vehicle.
