Why is it so important to choose the best oil?

Regularly changing your car’s motor oil and ensuring that you are using the best quality oil for your car is crucial in keeping your engine running smoothly and preventing damage. Motor oil lubricates the internal parts of the engine, preventing the moving parts from grinding against each other and causing damage, and also helps keep the engine cool by preventing overheating.

If the oil is not changed frequently, dirt, grime, and sludge can accumulate inside the engine bay, causing the moving parts to grind against each other and leading to serious damage. Impure and dirty oil can also cause damage and potentially require engine replacement in the future. Some oils contain additives, such as detergents and antioxidants, that help maintain the cleanliness of high-temperature surfaces, prevent oxidation, and keep the engine oil from thickening.

Choosing the right motor oil for your car can be challenging, but in this page, we’ll provide you with a list of the top 10 motor oil brands and products to ensure that you are using the best oil for your engine’s needs

Most Common Engine Oil Questions

Synthetic oil is designed to perform better and last longer than conventional oil. It is better at resisting heat, improving fuel efficiency, and helping your engine run more smoothly. It is usually more expensive, but most modern cars require synthetic oil.

This depends on your car and the type of oil you use. A good rule of thumb is every 8,000 kilometers for conventional oil and every 12,000-16,000 kilometers for synthetic oil. Check your vehicle’s owner’s manual for manufacturer recommendations.

 

Yes, you can switch between synthetic and conventional oil without damaging your engine. However, once your car has been running on synthetic oil, it’s best to stick with it.

The weight of motor oil, such as 10W-30, refers to its viscosity, or thickness. The first number (with the W for ‘winter’) refers to the oil’s viscosity at low temperatures, while the second number refers to its viscosity at high temperatures.

Some signs include the oil appearing dark and dirty, your engine making more noise than usual, the check engine or oil change light coming on, and your oil level dropping faster than usual.
