The right motor oil can be difficult to choose because there are so many options. To assist you in selecting the option that is best for your vehicle, we cut through the confusion.
What is Motor Oil?
The lifeblood of an engine is motor oil, a miraculous substance. Sludge, abrasive particles, and harsh chemical contaminants are held in suspension as it pumps through the running engine through tiny passages called galleries, cleaning, lubricating, cooling, and cushioning moving engine parts. To keep your engine running smoothly, you should change your old motor oil on a regular basis.

What Does Motor Oil Do?
Understanding the functions that motor oil serves in the health of your engine can help you appreciate the significance of selecting the proper oil. The primary function of oil is as a lubricant, keeping parts apart by creating a thin film of molecules that function as tiny ball bearings and keep them from rubbing against one another. Not only is it a lubricant, but engine oil also:
- Coats metal parts to prevent rust and oxidization
- Reduces friction between moving parts
- Dissolves and washes away deposits and sludge from inside the crankcase
- Circulates hot oil to the engine oil cooler to maintain the right operating temperature
- Neutralizes acids created from the combustion process
These protective characteristics may be compromised if the incorrect grade of oil is used.

Find the Correct Oil Grade
An engine oil grading system has been created by the SAE, or Society of Automotive Engineers. Engine oil of the common grade 5W-30 can be used as an example to explain how it performs in general terms.
The first part of the number, 5W, which stands for Winter, indicates how well it pours in cold weather. It flows better in the cold when the number is lower. The oil weight at standard operating temperature is indicated by the second component of the number, which in this case is 30. The higher this number, the thicker it is when it is warm.
In most cases, your engine oil cap will be marked with the grade you’re looking for. Additionally, you can find it online or in the manual for your car’s regular maintenance. Whenever your manual lists two possible grades, choose the one with the lower number if you want to drive in the winter. For instance, a car might need to use 5W-20 engine oil in the summer but 0W-20 oil in the winter.

Types of Motor Oil
Only a small part of the motor oil equation involves grade. The type of oil you use in the engine may be even more crucial. And if you’re wondering, “All engine oils the same, right?”, no they are not. Although they may all originate from the same base oil, which is refined from crude oil extracted from the ground, there are some very noticeable differences between the different types of oil, even though you can’t see them with the naked eye.
Conventional Oil
Before it can be used in an engine, crude oil that has been extracted from the earth using a variety of methods must first be refined. After impurities have been eliminated, it is combined with detergents and additives that are meant to keep your engine clean and safe.
After using conventional oil in the engine, it starts to lose its quality. It will become saturated with contaminants and particles that would otherwise harm the engine within a few months or a few thousand miles, and it will start to lose its protective properties. Oil changes are crucial because they take these dangerous compounds out of the engine for disposal.

Synthetic Oil
Contrary to what many people think, synthetic oil is not entirely made from scratch. Similar to how conventional oil is made, it is derived from crude oil. But refinement is a more exhaustive process. Due to the more uniform size of synthetic oil molecules, the engine is better protected from wear. It starts out as a higher quality base oil, which means it is more chemically stable, resists oxidation better, and won’t quickly lose its protective qualities.
In addition to having a better base oil, synthetic engine oil frequently contains top-notch detergents and additives. Because of these advantages over conventional oil, synthetic oil helps keep engines cleaner, experiences less wear, performs better at higher temperatures, and doesn’t degrade as quickly.
Synthetic Blend
Full synthetic engine oil has the drawback of being pricey. A synthetic blend or semi-synthetic engine oil is an affordable alternative that provides comparable advantages. Beginning with a blend of synthetic and conventional base oils, it is then given detergents and additives that are typically better than what you would find in conventional oil. Both auto manufacturers and service centers favor it. Additionally, it has evolved into the minimal standard grade in the majority of cars.
Which Oil Should I Choose?
The maintenance guide, which you should always follow, specifies the minimal type of engine oil your car needs.
The minimum requirement for engines in naturally aspirated vehicles is frequently conventional engine oil. You can upgrade to semi-synthetic or full synthetic engine oil, though, if you’d like your engine to have even more protection.
The type of oil required is frequently semi-synthetic or fully synthetic if your vehicle has a turbocharger, supercharger, or is a high-performance model. You shouldn’t switch to conventional oil because it lacks the qualities your engine needs to be protected.
How Often Should I Change My Oil?
Although changing the oil is routine, you should never skip it or wait longer than what your maintenance manual recommends. Since synthetic oil doesn’t degrade as easily, you can usually expect longer intervals, usually 7,500 miles or more. Every 3,000 to 5,000 miles for conventional oil, an oil change is typically recommended.

FAQs
What Oil Does My Car Take Honda Civic
Your Honda Civic uses synthetic 0W-20 rated oil. The Honda engine uses synthetic oil because it requires the lower viscosity that synthetic oil can achieve. Mixed synthetic fuels or regular oil are not intended for use in your car. Utilizing these oils can harm your engine and require expensive repairs.
How Do I Find Out What Oil My Car Takes?
The oil type and grade are typically listed in your car’s owner’s manual or maintenance manual, or they may be stamped on the engine oil cap.
What Car is 5W-30 Oil For?
5W-30 engine oil is an extremely common grade and is used by hundreds of vehicle types. However, to determine if it’s appropriate for your engine, look at the maintenance manual or oil cap for the required grade.
What is My Car Oil Capacity?
Locate the Vehicle Specifications section in your owner’s manual to learn how much engine oil your vehicle requires. Find out how many quarts your engine needs, and purchase extra in case you need to top off.
