How Much Oil Does My Car Need?

There are numerous reasons why your car needs to have the right amount of oil in it. One of the most important parts of maintaining a car is having the proper amount of oil. Your car won’t run well if there isn’t oil in it. In the long run, this damage might shorten the car’s lifespan significantly.

Fortunately, it needn’t be challenging to give your car the right amount of oil. In actuality, it’s not too difficult. Here CarMats will share with you how to calculate the exact amount of oil your car will need.

Let’s first explore the specifics of why oil is crucial for your car. There are numerous moving components in car engines, and these components can generate heat and friction. The oil just keeps the engine of the car lubricated while it absorbs heat. This keeps the engine from overheating and improves its performance.

Having said that, oil requires upkeep. You won’t put it in your car just once and forget about it for the duration of its life. Your car needs routine maintenance to keep it running smoothly, and oil changes are no exception.

Oil loses the thickness that helped make it so effective in the first place as it degrades over time. This indicates that it is unable to carry out its functions as effectively as it did before being added to the vehicle. Get into the habit of regularly checking the amount of oil in your car because of this. In the end, this can only be avoided by changing the car’s oil at the proper intervals. This makes it easier to guarantee that the oil is pure, effective and performing its function at the highest level. Additionally, the kind of oil your car uses can affect how often the oil needs to be changed.

What are the Different Types of Oils?

There are numerous varieties of oil, and what works for one vehicle might not necessarily work for another. Therefore, if you’re doing it yourself, it’s crucial that you make sure you’re using the right kind of oil.

The various kinds of oil consist of:

  • Conventional
  • Synthetic Blend
  • High-Mileage Synthetic Blend
  • Full Synthetic Oil
  • European Oils

Conventional Oil: This kind of oil is made from crude oil that is mined underground and is based on petroleum. It is more sensitive to temperature changes and typically costs less than other types of oil. Additionally, it is known to thin in the heat and thicken in cold temperatures. The tendency of this kind of oil to produce sludge is also due to the thickening of contaminants, oils, and carbon.

Synthetic Blend Oil: This kind of oil is a combination, as you might have guessed. Because it is both natural and man-made, it gives your car better performance and lubrication and protects the parts inside.

These oils don’t degrade as quickly as conventional oils, so they typically last longer. They are also better at withstanding heat, it should be noted. While a synthetic blend oil won’t be as inexpensive as conventional oil is, you still get a lot of value for less money than you would for fully synthetic oil.

High-Mileage Synthetic Blend: The high-mileage synthetic blend oil will be discussed next. This oil might be right for you if your car has at least 75,000 miles on it. You should start taking extra precautions once your car reaches this point. Making the switch to this kind of oil is one of these precautions. It has all the benefits of synthetic blend oils, plus better additives and cleaners.

These guards the car against incredibly high temperatures, wear, and sludge buildup. The additives primarily function to increase the engine’s lifespan. They safeguard piston rings, seals, and other things as well. To stop the oil from deteriorating due to oxidation, antioxidants have also been added.

Last but not least, detergents that keep your engine clean and remove sludge are also added. This is a fantastic alternative because they cost less than full synthetic oils while lasting longer than typical petroleum oils. win-win situation.

We’ve talked a lot about full synthetic oil, so let’s discuss this well-liked kind of oil. Full synthetic oil is essentially crude oil that has been purified and reduced to its simplest forms. These were created to satisfy the demands of motor vehicle engines. Additionally, this kind of oil contains additives made synthetically. These are more expensive than conventional oils, but because of the structure of their molecules, they also lubricate and clean out impurities better and last longer. This type of oil is also more heat-resistant than others, resists sludge buildup, and is typically less affected by temperature changes. Because of this, the engine won’t need to use as much full synthetic oil.

European Oils: European oil is last but not least. While this type of oil shares many characteristics with fully synthetic oils, it also contains unique additives. This has stricter emissions requirements. Because of this, a luxury, European-made vehicle typically uses European oil. The most expensive oil is this kind.

How Much Oil Does My Car Need?

Depending on the size of the engine, your car will need different amounts of oil. Your car’s engine will need less oil if it has a smaller one than a bigger one.

Of course, the best thing to do if you have any specific questions about your car is to consult the owner’s manual. That will give you the precise answers to the queries you have. You can also consult the website of the car manufacturer if you can’t find the answers you’re looking for there; just make sure you check the right year of the car. Another choice is to take it to the shop where a mechanic can assist you in determining how much oil your vehicle needs.

However, there are ways for you to accomplish that on your own. Generally speaking, the number of cylinders in your car’s engine will determine how much oil it needs. That implies:

  • You’ll need about 5 quarts of oil if your car has a 4-cylinder engine.
  • You’ll need about 6 quarts of oil if your car has a 6-cylinder engine.
  • Depending on the size of the engine, you’ll need between 5 and 8 quarts if your car has an 8-cylinder engine (so check your owner’s manual).

The cost may also differ depending on whether you decide to change the oil filter along with it or just the oil in the car.

How Often Should I Change My Car’s Oil?

How frequently you change your car’s engine oil depends on a few factors. These factors include the age of the car, the kind of oil it uses, and the kinds of driving situations you usually use your car in.

Modern lubricants have altered the traditional rule of changing your car’s oil every 3,000 miles. Most engines now need an oil change every 5,000 to 7,500 miles. Having said that, the type of oil your car needs may also have an impact on how often it needs to be changed.

For instance, you might be able to go up to 15,000 miles between services if your car uses full synthetic motor oil. The condition of the engine oil cannot be determined by its color, so you must adhere to the maintenance schedule outlined in your owner’s manual. Additionally, the vehicle’s age must be considered.

With regard to older vehicles, you ought to change the oil based on the mileage. Additionally, you should adhere to a more strict schedule if you drive your car in “severe” circumstances, such as frequent short trips (5 miles or less), in extremely hot or dusty environments, in constant stop-and-go traffic, or while towing heavy loads. In the owner’s manual, this will be covered in detail. For more recent vehicles, the instrument panel will frequently display a warning. If you are unable to locate it, you should adhere to the instructions in the owner’s manual.


In order to maintain your car properly, you must make sure that it has the appropriate level of oil. In light of this, it’s crucial to check that your car is using the right kind of oil. A long lifespan for your car can be ensured by checking on both of these issues. No matter if it’s a gas or diesel engine, you can treat any oil-lubricated system with products like our Performance Booster Oil Additive. The Performance Booster stops rust, oxidation, and normal friction to reverse engine wear.
