Lexus RX 350 engine oil capacity

Driving with too much or too little engine oil runs the risk of causing damage to your engine or other vehicle components. So, how much engine oil does the Lexus RX 350 need?

The answer might depend on your vehicle’s model year and engine type, which can vary depending on

trim level

and other configurations. If you’re not sure what kind of engine your RX 350 has, you can refer to your owner’s manual, the label on your driver’s side door jamb, or the information on the engine itself.

Your owner’s manual should also list your engine oil capacity based on your engine type.

The 2012 Lexus RX 350, for example, has an oil capacity of 6.4 quarts, or 6.1 liters, while the 2021 Lexus RX 350 has an oil capacity of 5.7 quarts or 5.4 liters.

What kind of oil does a Lexus RX 350 need?

The type of oil your Lexus RX 350 requires will vary depending on your model year, too.

That makes it important to check your owner’s manual to verify the right oil type for your Lexus RX 350. Using the wrong oil type could end up causing serious damage to your engine.

The 2009 Lexus RX requires 5W-30 motor oil, for instance. Meanwhile, the 2021 Lexus RX 350 requires synthetic 0W-20 with an oil grade of ILSAC GF-6A multigrade oil.

Let’s break down the 2021 recommendation further. The 0W-20 is the oil’s viscosity or thickness. The “0” refers to its viscosity at cooler temperatures before your engine has started up, while the “20” refers to its viscosity at normal engine operating temperatures—about 212 degrees Fahrenheit.

“ILSAC GF-6A” refers to a set of specifications and quality standards that your engine oil has to meet to be considered acceptable for your vehicle.

Lexus

typically recommends choosing Toyota Genuine Motor Oil as a first pick, but what’s most important is that the brand you choose has the correct viscosity and certification.

And what about synthetic oil? In most cases, vehicles that use conventional oil can use a synthetic blend or full synthetic oil, and you could be able to drive long distances between oil changes. However, if your vehicle requires synthetic oil, you shouldn’t use conventional oil.

Not sure where to start when it comes to engine oil options? Most auto shops have search tools that will let you check the compatibility of a certain oil type with your vehicle.

The manufacturer’s recommendation: For the Lexus- and Toyota- approved choice, use

How often to change oil on a Lexus RX 350

How often you should change your engine oil on your Lexus RX 350 depends on what kind of motor oil you’re using and what kinds of driving conditions you’ve been experiencing.

As a general rule, you could expect to need to change conventional oil on a Lexus RX 350 every 3,000 to 5,000 miles, or 7,500 to 10,000 miles if you’re using synthetic oil. You can check your owner’s manual for the recommended oil change interval for your model year.

That said, if you’re regularly driving up steep inclines, in dusty environments, or if you’re regularly pushing your Lexus RX 350 to the limit, you might end up needing to change your oil sooner than you’d otherwise need to.

Since when you should change your oil can vary so widely, it’s a good idea to check it periodically. Most car experts will recommend checking your engine oil levels about once a month, or whenever you’re refueling at the gas station.

The following are some signs that could mean it’s time for your Lexus RX 350 to get an

oil change

Motor oil is dark brown or black in color

Engine oil has a grainy texture

Smells of oil, burning, or smoke coming from the engine

How to change your oil and oil filter

When it’s officially time for an oil change, here’s what you’ll need to get it underway:

Socket wrench

Filter wrench (used to remove old oil filters)

Drain pan

Fresh oil

New oil filter

Replacement washer for drain bolt

Gloves

Towel(s) to clean up

Once you have everything you need, you can get started by letting your engine run for a few minutes—this helps the oil warm up and makes it easier to drain. Then, you can head to the front of your vehicle, prop open your hood, and get into it:

Remove the oil fill cap

Underneath the vehicle, remove the drain bolt and washer

Let the oil empty into the drain pan

While you wait, remove your old engine oil filter and install the new one, following the package instructions as needed

After the oil has finished draining, replace the drain bolt with a new washer

Refill the engine with fresh oil, using your dipstick to verify it’s at the proper level

Replace the fill cap

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.

Let your engine run for a few minutes again to verify everything’s working as it should, and check around for any potential leaks. After letting your engine cool off again, you can check your oil one last time to verify it’s at the proper level, topping it off if you need to.

That’s not all! The final step of changing your oil is properly disposing of the old engine oil. Motor oil is a hazardous material, so you can’t just dump it down your drain or throw it out with your regular trash. Many cities have drop-off locations where you can recycle used engine oil.
