Mazda 3 engine oil capacity

Since 2013, the Mazda 3 oil capacity has stayed the same, but it varies depending on which engine size you choose. There are three engine options for the Mazda 3, here are the oil capacities for each of them:

2.0-liter 4-cylinder: 4.4 qt or 4.2 L

2.5-liter 4-cylinder: 4.8 qt or 4.5 L

2.5-liter 4-cylinder Turbo: 5.1 qt or 4.8 L

All these oil capacities are the volume of oil needed when you replace the oil filter, which is recommended with each oil change. If you choose not to replace the filter, expect to need about 0.2 qt less oil.

What kind of oil does a Mazda 3 need?

Like the oil capacity, the recommended oil changes a bit depending on the engine. The recommended oil for the Mazda 3 is 0W-20 motor oil, unless you have the turbo engine. The recommended oil for the 2.5-liter turbo engine is 5W-30 motor oil.

We recommend using synthetic oil for your Mazda 3 to optimize performance and engine health, especially if you have a turbo engine.

These numbers refer to the oil's viscosity for readers who don’t know what “0W-20” means. When you see an oil with two numbers, it means it is a multi-grade oil, or it has been measured and rated for two temperatures. The first number (0W) refers to the oil’s viscosity in cold temperatures (measured at 0°F). The second number tells you the oil grade at normal operating temperatures of 212°F.

How often to change the oil on a Mazda 3

If you opt for synthetic motor oil, experts recommend changing your oil every 7,500 to 10,000 miles. Conventional oils tend to have a shorter lifespan, needing replacement after around 3,000 to 5,000 miles.

Those are some pretty large ranges. Many factors can affect how far your oil will take you. The best practice is to check your oil regularly for signs that it is time for an oil change. It is also typically a good idea to change your oil every six months to one year regardless of how much you've driven.

Some common signs that it’s time for an oil change include:

Black or dark brown oil. Clean oil should be transparent amber or light brown.

Oil that feels coarse or gritty

Strange

sounds

or smells coming from your engine particularly smells of oil, burning, or smoke

Reduction in your car’s power or fuel efficiency

How to change your oil and oil filter

So you know how much oil you need for your Mazda 3, and what type of oil to get. Of course, you can always take your car to the shop to change your oil, but doing it yourself can save you roughly $100 in labor costs.

If you’ve decided to change your oil yourself then you’ll need some tools to get the job done, in addition to the requisite oil. You’ll need a socket wrench, a drain pan, a filter wrench, and a new oil filter. Before you start draining your oil, run your engine for a few minutes to bring it up to normal operating temperature.

Then, turn off the engine, pop the hood, and follow these steps:

Locate and remove the oil fill cap

Position the oil pan under the engine and remove the oil drain bolt and washer

Remove the old filter and let the oil drain completely

Install the new filter

Replace the drain bolt with a new washer and tighten it to 29 lb-ft

Refill the engine with clean oil

Replace the oil fill cap

Run the engine for a few minutes and look for any leaks

Dispose of the dirty oil responsibly by taking it to a nearby recycling center

After changing your oil, it’s a good idea to turn on your car and let your engine run for about 30 seconds before you check the oil level. This will give you a more accurate measurement, and you’ll be able to top it off if necessary.

Don’t forget regular insurance policy maintenance

Once you’ve taken care of your car maintenance, it might be time to turn your attention to your
