Q) Which engine is oil good to use?

Things to Consider Before Choose Engine Oil 2022

Don’t trust in a cock and bull story! The market is bundled with many engine oil options of different brands, those who have appealing advertisements and false information.

These make people skeptical and often lead them to the abyss. In this era of posh and careful marketing strategy, buying something seems the toughest job. Not to worry, as I am here to lessen your pain. In this article, I will review some of the best engine oil of the present time.

In the reviews, you will get cent percent honesty. You will also learn some crucial buying tips, and the answers to some often asked questions. So, what are you waiting for? Let the real journey begin. I will open with buying tips first. Let’s start:

Consider Type

Engine oil can be of many types based on the material by which they are made. While buying engine oil, your first concern should be the type. Consider which type is good enough for the engine of your vehicle.
Let’s help you out on that with a brief detail about the types.

Conventional: The most common engine oil type is conventional, which is less compelling when compared to fully synthetic, synthetic blend or high-mileage engine oils. In new cars, conventional is common.

Anyway, a conventional oil approximately let you go 3000 to 5000 miles in between oil changes.  If you wish to go for conventional engine oil, 5W-20 or 5W-30 is the proper judgment.

Synthetic: Fully synthetic engine oils are having immense popularity in recent times because of their performance on high-performance automobiles.

If you prefer to acquire the best synthetic engine oil, remember they are designed for engines with higher RPM and temperate. In a nutshell, synthetic motor oils are for heavy-duty vehicles.

Synthetic Blend: You can call them hybrid as they are a blend of synthetic and conventional motor oil. Those oil offers excellent protection and enhance engine performance compared to conventional types. Also, these are less expensive.

High-Mileage: These motor oils are produced for some specific vehicles with a high mileage. By high-mileage vehicle, I meant those cars that has over 75,000 miles on the engine.

Consider Viscosity

If you figure out the correct viscosity for your engine based on the weather in your area, you are a champ in buying engine oil. If not, ready to experience some real trouble. Viscosity is an essential factor to consider. Based on external temperature, operating temperature and load vehicles get a viscosity rating from their manufacturers.

  • Gasoline engines usually have viscosity levels of 5W-30, 5W-20, and 0W-20.
  • Diesel engines generally have viscosity levels of 15W-40 and 5W-40.

These numbers show the ability of motor oil to resist thickening in low temperatures and thinning at high temperatures. “W” is referring to the thickness of oil in chilly temperature.

Most engine oils are multi-grades today, which means they have a viscosity of two grades. You don’t have to use thin oil in winter or thick oil in summer if you select multi-grade oils. Remember the lower the number before ‘W,’ the better it will perform in winter.

Additional Consideration

If you have a sports car and you love to drive fast, high-mileage motor oil is what you need. Some goes for those who carry heavy loads on their car frequently.

Types of additives on the oil of different brands differs from each other. Many of the brand use anti-foaming agents, anti-wear agents, antioxidants, detergents, corrosion inhibitors etc. Decide which additives are best for your vehicle.

You should know the need of the engine. It might hurt it if you use an improper mixture of conventional oil and synthetic oil. It can ruin the strength of synthetic characteristics. Remember that few old cars works better with conventional engine oils whereas modern cars runs better with synthetic oils.

Price Consideration

Best engine oils can be plus or minus twenty dollars. If you don’t want to spend too much money still need a better option, synthetic oil is an excellent choice.

If you can pay over 20 dollars, you will get full synthetic motor oils. Based on your budget, you will find something on the best engine oil reviews we have mentioned below. Look which one is suitable for you.


Engine oil is an integral component of a car to perform better. If you don’t use a wonderful one, your car will not run smoothly. Using a worse kind for an extended period can ruin the engine completely. Therefore, it is essential to know everything and buy a good option.

As discussed, I have mentioned some of the best engine oil reviews with practical buying tips. I hope this will help you out. I also answered some questions people asked often.

So, now it is my time to say goodbye to you all. If you still have anything else to say, feel free to ask in the comment section. I will try to answer honestly. Anyway, this is not the end, my friend. We will surely meet again in this blog with some other essential car article. Keep an eye on our blog and share so that we can grow.
