Some engine oils are produced solely for extended performance vehicles, high mileage vehicles, motorcycles, or diesel engines. Therefore, you should consult the vehicle guidebook and understand which engine oil is recommended.


Another essential factor to consider is the compatibility of the oil you intend to purchase with the existing oil. Ensure that the brand you buy is compatible with other types of oil or that the old oil will need to be completely drained. Some of the 5w30 motor oils are also manufactured for specific vehicle models. Therefore, before purchasing, be sure to purchase high-quality oil that is compatible with the model, year, and make of your vehicle.

The five indicate the oil’s viscosity at low temperatures (usually in winter), and the second number indicates the viscosity at operating temperatures.

What Is The Best Brand of Motor Oil?

Motor oils come from different brands, and the best brand will depend on several things, such as your vehicle model, make, year of manufacture, and even usage. Different brands have their formulas to suit different situations. Nevertheless, some of the respected companies with the best motor oils are Valvoline, Mobil 1, Royal Purple, Castrol, and Liqui Moly.

Would It Make Any Difference Which 5w30 Oil I Use?

The type of 5w30 oil you use is essential. This is because 5w30 oils are made differently, and their formulation process differs. Currently, some 5w30 oils are made for certain types of vehicles, makes, and even specific mileage.

What If You Use The Wrong Motor Oil?

Using the wrong car oil can reduce lubrication and shorten engine life. We recommend that you consult your car’s manual for the oil recommended by the manufacturer. If the vehicle manufacturer indicates that synthetic oil should be used, it is advisable to follow it.

Using the wrong oil can lead to poor efficiency, engine noise, oil leaks, a burning smell, and damage to engine parts because they are not well protected. If you find that you have used the wrong engine oil, it is recommended that you change the oil entirely before damaging the engine.
