If you want to do everything you can to protect your car’s engine, you need to know how to maintain it. How much oil does my car need?, you may be wondering. This is important to understand if you plan to do your own oil changes or need to top off the system.
In this guide, we cover how much oil most engines need. We also take a look at where to find the specifications, so you can properly treat your vehicle.
How much oil does my car use?
It really depends on the type of engine your car has. Most engines today have between five and six liters of oil. However, compact four-cylinder engines can hold as few as four quarts, while a large truck engine can hold as many as eight or nine.
Most four-cylinder engines have a capacity of five liters or less because the engine is smaller. In comparison, a larger six-cylinder can hold around six liters. At the higher end of the spectrum, an eight-cylinder can hold five to eight liters of oil.
Where to find your car’s engine oil capacity
1. Owner’s Manual
The traditional way to find out what your vehicle needs is to read the owner’s manual. This manual will not only tell you how much oil to use, but it will also show you which type is best.
If you lost your manual or didn’t receive it with a used car, you may need to try one of our other options. You can also buy a new one, possibly on eBay or another online platform.
2. Online resources
There are many ways to find information online, and the web provides an outlet for everything you need. You can search a database on a local auto parts store’s website.
You can also Google the information and see what’s going on. Just make sure you get the specifications from a reliable source or else you could end up in a mess. A reliable service that you can use for free is Castrol Web.
Contact your local dealer for help. After-sales service can find the information for you. The parts department may also be ready to help.
You will need to provide them with the model, year, and make of the car. You can also ask about the size of the motor. If you don’t know all of this, just give them the VIN, or vehicle identification number.
Remember, you don’t have to stay with the dealership. If they don’t give you the help you need, contact an independent mechanic.

Signs It’s Time for an Oil Change
Why do you need to know how much oil is in your vehicle? When you perform an oil change, you will need to fill the system. Here are some signs that indicate it is time to drain and refill the oil with the proper amount.
- The oil light comes on. This indicates that the oil level is low. You may need to change it or just fill it out a bit.
- The oil pressure gauge indicates a low level. Not all vehicles have this indicator, but it is useful to know when there is a problem.
- The engine running poorly. By changing the oil, you help remove the deposits on the tappets that are causing the problem.
- Lower fuel economy. As engine oil becomes dirty, it becomes more difficult for the engine to run efficiently. You will notice a difference in your vehicle’s gas mileage.
Any time your engine seems to be running rough or you notice a change in performance, you should check your oil levels.

What happens if the engine’s oil level is too low?
You don’t want to run your engine with low oil. It is necessary to lubricate the internal parts of the engine. In addition, it is necessary to reduce friction in the engine. What you may not know is that motor oil also works to keep your engine running at normal temperatures. For these reasons, you need motor oil to keep your engine running at its best.
For a short period of time, you can rev the engine without a full reading, but only if it is slightly low. You don’t want to go over a liter for any reason. Otherwise, you will wear out the engine more, especially when starting. It could also damage valuable engine parts, such as valves, cam bearings, and tappets. If you end up needing an engine rebuild, it will cost much more than putting a quart of oil in the vehicle.
What happens if the engine oil is too high?
On the opposite end of the spectrum, it is possible to overfill the engine. You may think there isn’t too much of something, but that’s not the case with your engine. When there is an excessive amount of engine oil in the crankcase, the crankshaft and pump begin to aerate it. The motor oil turns into a foamy mixture.

This mixture creates a huge amount of air that moves between the engine components. The oil pump will pick up a lot of air as it moves the oil. Additionally, if you drive at higher speeds, such as on a highway, the crankshaft begins to rotate up to twenty times per second. This leads to greater aeration. As the oil becomes bubbly and foamy, it can no longer lubricate the internal parts, causing serious engine damage in the future.
The oil level should always be read between the two lines on the dipstick. These lines should say something like “Complete” and “Add.” If the levels are not at these markers, you must take steps to protect the car’s engine from damage.
