Find The Right Engine Oil For Your Car

Every engine oil will have its viscosity grade labelled on the packaging. This will look something like 0W-20, 5W-30 or 5W-40. This grading is used to measure how thick / fluid the oil is and help ensure you buy the right oil for your car. The lower the viscosity grade of the oil, the more fluid and thinner it will be than those with a high grade (higher numbers) which will be much less running and thick.

When topping up or changing your cars engine oil it is really important that you use the correct type of oil.

If you’re unsure which engine oil your car or vehicle needs, the manufacturer will always provide the information in the car service manual. However, to save you time and effort 'What Car Oil' has done the research for you and we have a comprehensive list of every car make, model and trim along with the engine oil you need to use.

The Importance Of Engine Oil

Oil is an essential part of an engine. Without oil, the engine and ultimately the entire car would not run properly. The oil performs a number of critical jobs in the engine: lubrication, protection against wear and corrosion, cooling and much more. However, an engine oil is not always just an engine oil, but varies in its composition. The engine for your car can therefore require mineral oil (base oil obtained directly from petroleum), semi-synthetic oil (mixture of mineral oil and synthetic oil) or fully synthetic oil (oil produced synthetically).

In addition to the different production methods, viscosity is an important factor. A viscosity of 0W is currently the thinnest oil for a car. The higher the viscosity, the thicker the oil. However, when looking for the right oil for your car we need to look beyond just the viscosity. For example, for 10W oil we have grades such as 10W-30 or 10W-40. This secondary code designates a multigrade oil. A single-use oil like 10W is primarily designed for certain months of the year. A multigrade oil like 10W-40 is designed for a whole year.

The specification for an engine oil is synonymous with the viscosity. The best known include SAE and ACEA. Guidelines and values ​​for an oil set by car manufacturers or institutes, a motor oil may only bear this label if it satisfies the predefined guidelines.

So if you know that your vehicle requires an engine oil with a certain viscosity and a specification such as SAE or ACEA, the only question left for you as a buyer is which brand to choose. Brands like Liqui Moly or Castrol are often used because their reputation promises high quality. So is only Liqui Moly or Castrol motor oil good for your vehicle? Definitely not!
