To determine what oil to use for your car, you can use an oil selector tool provided by various oil manufacturers such as Mobil, Pennzoil, and Castrol. These tools will recommend the best motor oil for your vehicle based on factors such as make, model, and year. You can also refer to your vehicle owners manual, which will define the engine oil viscosity and type that the car manufacturer recommends. The owner's manual may also include details for cold or hot climates.
When picking an oil for your engine parts, the most important thing to consider is the oil's viscosity, which is usually written in a format like 5W-30. Viscosity ratings apply across all types of motor oil, whether traditional oil or synthetic oil. The most common oil you'll find in modern cars is the 5W-30.
It's important to use the correct oil for your car, as engine oil is designed to lubricate the moving parts of your engine, protect against wear and tear, and help keep your engine running smoothly. Using the wrong oil or not enough of the correct one could lead to serious damage to your vehicle. Depending on the type of oil your vehicle requires, you should also consider its additives.
