Optimal Performance For Your Engine

Reading Time: 3 minutes
A blog on how engine oils affect your car, and how to use it to keep your car in optimal performance. Read here to find out more.

The oils in your engine are the most important factor of keeping your engine healthy. A lot of focus is put on how you drive, but the type of oil you use can also affect how well your engine performs. Engine oils are made with different types of additives that give your car the performance it needs to run efficiently.

The additives in Engine Oils are there for various reasons:

  • Antioxidants – reduce viscosity breakdown caused by heat and oxidation
  • Corrosion inhibitors – prevent rust and corrosion from forming in the engine
  • Detergents – clean up deposits that build up on engine parts called sludge, which can cause excessive wear in an engine.

Types of Engine Oils There are many types of motor oils out there, but we can break them down into two major categories: synthetic and conventional. Conventional motor oils are called “minerals” because we mostly extract them from crude oil. Synthetic motor oils are created when refining crude oil is done at a higher temperature, creating more refined base stocks for lubricants that produce better performance.

Synthetic Oil vs Conventional Oil: Which is Better?

Conventional oil will work fine for most cars, but synthetic oils have some advantages over conventional oils, including durability and protection from dirt and small pieces of debris. 

Synthetic oil is derived from a chemical reaction between various hydrocarbons and an alcohol compound. The resulting product is a type of oil that is completely man-made. It has all the benefits of petroleum-based oil, but in some ways it is superior.

This synthetic oil is frequently used in high-performance cars because it has better thermal stability than conventional oils. This allows it to resist breaking down as easily as conventional oils do when the engine reaches high temperatures. This means that synthetic oils are better suited for high-performance engines than conventional oils, which makes them ideal for racing vehicles.

Total synthetic oils are used in both older and newer engines and can be used for both gasoline and diesel engines. They have good low-temperature fluidity and good thermal stability and anti-oxidation properties. They have solvency properties that help remove deposits and keep the engine clean, along with anti-wear properties that protect against damage caused by metal-to-metal contact inside the engine.


Engine oils come in all different viscosities — a term referring to how easily it flows. The viscosity rating can range from 5W-50, but most engines use 10-40 or 20-50 engine oil. The lower the number, the thicker the viscosity of the oil, so less heat is needed to warm it up enough so that it can flow through your motor. Oil with higher numbers requires more heat to warm it up, so some heat has to be removed from other parts of your engine in order for them to work properly.

The thicker and colder the oil is, the better it can protect against wear and tear in extreme temperatures or heavy loads. However, thinner oils allow for faster acceleration because they can flow through your motor with much less resistance.

The engine oil reduces friction and absorbs heat so that the engine can run smoothly. It also protects the metal surfaces from corrosion and prevents them from overheating. In addition, engine oil helps to clean the motor by collecting deposits of combustion residues, preventing them from clogging up the engine.

The engine oil is the lifeblood of the car. It protects the engine and its moving parts against wear and tear, heat and corrosion. Therefore, it is very important to choose a high-quality lubricant for your vehicle.

But how do you decide which engine oil is best suited to your car?

They designed engine oils specifically according to the type of engine in your car. The viscosity is an important factor when choosing an oil: we typically use thinner oils in cold climate conditions for their better flow properties, whereas thicker oils are used in warmer climates for their increased thermal stability and resistance to viscosity breakdown during high temperatures.

There are various types of engine oil based on their application:

  • Conventional engine oils (designed for cars manufactured before 2000)
  • Synthetic engine oils (designed for cars produced after 2001)
  • Diesel oils (for diesel engines only)
  • Bioengine oils (for environmentally friendly vehicles)
