2011 Infiniti G37 engine oil capacity

Let’s cut straight to the chase—whether your G37 is equipped with the 2.5-liter V6 engine or the 3.7-liter V6, it needs 5.2 quarts of oil for each oil change.

In this case especially, it’s important to keep the difference straight between the G37’s displacement—which is the volume the six cylinders take up in the engine—and the G37’s oil capacity, which is how much oil the engine needs to stay running smoothly.

What kind of oil does a 2011 Infiniti G37 need?

Now that you know how much oil to buy, you’ll need to know the kind of oil to look for on the shelves. With so many different oil options, it can feel daunting if you don’t know what you’re looking for—but for the 2011 G37, you’ll need to hunt down SAE 5W-30 full synthetic oil.

Infiniti

recommends their Genuine Infiniti/Nissan Motor Oil, but another

high-quality brand

of the same specifications should also do the trick.

What do those mysterious numbers and letters mean? The SAE signifies that the oil was coded by the Society of Automotive Engineers, which means the oil is legit. The oil’s viscosity—or thickness—is symbolized by the numbers in the oil grade.

In this case, the 5W means the oil has a relatively low viscosity in winter temperatures, and the 30 means it’s still thin for higher temperatures, like the G37’s operating temp. Basically, this means the oil in your G37 will be thin enough to keep your engine working well in freezing weather but it’ll still protect your engine when the car is running extra hot. Using the right oil grade ensures your G37’s engine will run as smoothly as possible.

How often to change the oil on a 2011 Infiniti G37

An oil only works well when you change it at the right time—and with the 2011 Infiniti G37, you can probably get by with changing your oil every 7,500 to 10,000 miles since it’s got the synthetic blend to give it extra lubrication.

That being said, you’ll still want to check your oil regularly to make sure the oil is in good condition. Around once a month (or every other time you fill up your car), inspect your oil for the following signs of needing a change:

The oil is dark brown, muddy, or black (clean oil is light brown or amber)

The texture of the oil is sandy or coarse

You notice a smoky or burning smell

You’re hearing abnormal

engine noises

Your G37 isn’t performing as well

How to change your oil and oil filter

Now that you know all the ins and outs of your Infiniti’s oil, it’s time to

change your oil

. Of course, you can always take your car to a lube shop to get it changed professionally, but that’ll run you an average of $80 to $110.

If you’ve decided a DIY oil change is the way to go, you’ll want to gather all your materials first. Here’s what you need:

A jack or ramp to lift your car

A new oil filter and O-rings

Socket wrench

Drain pain

Oil filter wrench

Funnel

Rags

When you’ve assembled the tools—plus 5.2 quarts of 5W-30 motor oil—you’re ready to roll. Make sure you’re parked on a flat surface, then turn your car on for a few minutes to warm your oil up. Then you’ll just turn your car off, pop your hood, and follow these steps:

Jack your car up enough to get under.

Remove the bolts of the engine cover and move it to the side.

Remove your oil fill cap/plug from under the engine. Place your drain pan directly underneath.

Grab your filter wrench and remove the old oil filter, letting the oil completely drain from it.

Wipe down the area before installing your new oil filter, adding some of the new oil to the gasket.

Install the new oil filter, being careful not to over-tighten.

Put the oil drain bolt and plug back in place, then use your funnel to add the new oil into your engine.

Put your oil filler cap back on.

That’s it! When you finish, check your dipstick to make sure that you’ve added the correct amount of oil. Turn on your G37 to check for any leaks around the new filter and drain bolt.

If all goes well, your dashboard oil light may turn off automatically—but just in case, you can

reset it yourself.

The easiest way to legally dispose of the old oil is to pour it into the new oil’s empty bottle(s) and take it to a local auto parts store or lube center. Never put old oil into the garbage.
