2010 Mazda 3 engine oil capacity

The 2010 Mazda 3 has an engine oil capacity of 4.5 quarts. That means you can pour 4.5 quarts of oil into your engine after the old oil has been drained.

The 2010 Mazda 3 has a 2.0 L 4-cylinder engine, which gets 148 horsepower and 135 pound-feet of torque. The 2.0 L in the engine’s name is the engine displacement—the amount of volume its four cylinders take up—and not the engine oil capacity. Make sure not to confuse these two numbers.

What kind of oil does a 2010 Mazda 3 need?

With so many different engine oils on the market, it's important to purchase the oil that’s right for your engine. According to the 2010 Mazda 3 owner’s manual, you should fill your engine with 5W-20 engine oil.

If you are not sure what that means, the numbers in the oil indicate the viscosity or thickness of the oil. The first number is the viscosity at cold temperatures (thus the W for winter), while the second number is the viscosity at your engine’s regular operating temperature.

Mazda also recommends that you use a fully synthetic oil as this is made to help your engine run more smoothly, and it will last longer between oil changes.

How often to change oil on a 2010 Mazda 3

While cars that need conventional oil will need an oil change every 3,000 to 5,000 miles, the 2010 Mazda 3 takes synthetic oil and can go 7,500 to 10,000 miles between oil changes.

However, there are some signs that you need to change your oil sooner, regardless of how long it's been since your last oil change. Watch out for these problem signs:

Your motor oil is dark brown or black

The oil feels coarse or gritty

The engine is making strange noises

Unpleasant smells are coming from the engine

Your vehicle’s performance has dipped

How to change your oil and oil filter

With all the above information, there’s only one step left: actually changing your oil.

To do so, you’ll need the following equipment:

Socket wrench

Drain pan

Replacement filter

Bottle of engine oil

Let your car run for a few minutes to warm up the engine—this will help the oil drain. Turn your car off and, after making sure your engine is not too hot, you can pop the hood and get to work.

Unscrew the fill cap. If it’s stuck after you’ve drained your oil, your car won’t be able to move

Put the drain pan under the oil drain bolt

Undo the oil drain bolt from under your car

While the oil drains, replace your oil filter

Once the oil is drained, replace the oil drain bolt using a new washer

Pour fresh motor oil into your car

Rescrew the fill car

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.

You’re done! Let your car run for a minute to see if there are any leaks or if a dashboard light has popped up. Otherwise, the last step is disposing of the old motor oil—you’ll want to place it in a sealable container and bring it to a recycling center.
