Oil Type Comparison

Motul 8100 is a full synthetic motor oil which has proven to provide exceptional results in terms of protection to the engine by minimizing its wear, inhibiting friction with its extra ordinary lubrication properties. In addition, the motor oil keeps the engine clean from sludge deposits or any harmful build ups by providing oil film resistance.

In comparison, the Mobil 1 motor oil with full synthetic properties, is made to lubricate the engine elements of the car effectively. It is worth sharing here that the viscosity retention of Mobil 1 is high and does not compromise the efficiency of engine. The life of engine parts is certainly high with this motor oil as it does not let the sludge to build up on the valves of the engine.

Comparing Additives

Choosing the right additive for manufacturing engine oil is much important because it is imperative to the stable running of the engine. Here, Motul 8100 has blend of different on purpose additives and Mobil 1 contains ZDDP as an additive.

Motul 8100 is made with a unique mixture of certain additives which help keep the oil clean and environmentally safe with optimum performance. These additives significantly contain anti-wear agents, anti-foam, anti-rust, viscosity index improvers, detergents and anti-oxidants.

On the other hand, Mobil 1 has a higher level of ZDDP (1,000 ppm) and a small amount of phosphorus and detergents. This unique combination helps engines to achieve over all high performance and safety over an extended period of drive.

Engine Performance Comparison

Let’s analyze some of the important factors for both of these engine oils below:

Catalytic Converter Performance

There may be many reasons behind the catalytic converter failure, including false timing, spark plugs, and improper fuel mixture.

Motul 8100 makes use of modern engine technology to help the catalytic converter safe by protecting the oil. This is achieved by preventing oil from evaporation and combining with other harmful substances. The presence of anti-oxidants in this motor oil further helps and protects the oil particles from breaking down under harsh weather conditions.

Besides, Mobil 1 delivers extended performance with advance protection against engine wear. It ensures engine efficiency and longevity, making it suitable for both gasoline and fuel injected engines. Thus, it is highly applauded by most high performance and luxury car manufacturers around the world.

Reduction of Sludge build

Good synthetic motor oils use different kind of additives to address sludge issues as it can easily deteriorate the performance of engine.

Motul 8100 motor oil is composed of specific synthetic base stocks with modifying molecules to help maintain the oil pressure and provide excellent oil film resistance. In addition, there are cleaning agents present as additives to keep oil clean and sludge free.

In the case of Mobil 1, it has fewer contaminants. The oil has been manufactured in such a way that it resists the creation of sludge and prevent harmful deposits from accumulating.

Oil Burn-off protection

Oil burns off may lead to degraded engine performance, it may be caused due to the evaporation of oil particles which occur because of heated up engine for long intervals.

Motul 8100 uses advanced technology which helps maintain the oil pressure and prevent harmful emissions that can damage the engine. The lubrication property of the oil also controls the oil consumption and reduces the evaporation of oil particles as well.

Besides, Mobil 1 has provided with sufficient low viscosity grades to gain engine efficiency even in higher temperature conditions, resulting in excellent overall performance.

Minimizing Engine Wear-Off

Additives such as anti-wear agents in synthetic motor oils are used to reduce engine wear off and to achieve a long lasting performance.

Motul 8100 has an incredible lubrication property which provides excellent wear protection to the engine. The anti-wear agents reduce friction between the metal surfaces to minimum. Detergents in the oil keep the oil clean and easy to flow.

Mobil 1 uses detergent agents, protective additives and several anti-oxidants to reduce friction to minimum in any part of the engine.

Engine Seals Protection

Engine seals are important cover for the engines and require protection.

In Motul 8100, engine seal is protected by keeping the motor oil clean with the help of detergents present in the oil. They also reduce any sludge build-up and harmful deposits from accumulating.

Mobil 1 has the best active cleaning agents to prevent sludge or any harmful substances to stick. These additives ensure a protected and smoothly running engine to operate at its full potential.

Improved Fuel Economy

Several additives are added in motor oils to keep engine in good health and shape, improve performance and improve fuel economy.

Motul 8100 is best known for its environment friendly properties as it uses less fuel and emits less carbon. The anti-wear agents help protect the engine from wear and tear, boosting its performance and the detergents keep the motor oil free from dirt and sludge.

Besides, Mobil 1 has some inherently present fuel saving ingredients, which can avoid high friction rates and acidic accumulation that may adversely affect the fuel economy percentage. The protective agents in the motor oil are to sustain the fuel economy performance as well.

Viscosity Comparison

Viscosity of motor oils is one important parameter to consider in evaluating the overall performance of any given oil. It determines the strength of the lubrication and efficiency of the oil in different operating temperatures and preventing the engine and its parts from friction.

Motul 8100 motor oils is available in 3 different viscosities or grades, the grades significantly tell if the oil is suitable for lower or higher temperatures. Motul 8100 grades are SAE 0W-30, 5W-30 and 5W-40. In 0W-30, 0 stands for the grade at low temperature with W indicating winters and the digit 30 shows the grade at normal temperature.

Mobil 1 grades

Mobil 1 too offers a variety of viscosity grades to support the engines of different types of cars, trucks, vans etc. For example Mobil 1 (Truck & SUV) SAE 5W-20 is for gasoline powered trucks and SUV engines, Mobil 1 (High mileage) SAE 5W-30 is suitable for higher mileage vehicles, Mobil 1 SAE 10W-30 is designed for domestic and imported cars and similarly Mobil 1 SAE 15W-50 is for performance vehicles.

Oil Change Frequency Comparison

Fully synthetic motor oils are manufactured to deliver higher mileage and optimum performance before require to be changed.

Motul 8100 gives excellent performance and does not require frequent oil change. However, it is recommended to change oil after every 3000 miles.

While Mobil 1 delivers extra ordinary mileage and requires change after every 10000 miles, otherwise the engine can degrade its performance.

Mobil1 wins here!

Cost Comparison

The costs of both motor oils are listed below:

  • The Motul 8100 full synthetic costs $43.96 for five quartzes.
  • The Mobil 1 costs $22.37 for five quartzes.


The Motul 8100 is fully synthetic motor oil, designed for modern cars operating on gasoline or diesel engines to achieve great results in terms of engine performance, better mileage, longevity of the engine and its parts.

Whereas, Mobil 1 is state of the art fully synthetic motor oil which contains a unique blend of certain additives to provide far better results than the contemporaries. It has a range of oils designed for all types of modern gasoline powered vehicles, including High-performance turbocharged, supercharged fuel injected engines found in SUVs, light vans and light trucks.
