With good fuel efficiency, a high dependability rating, and seating for up to eight, the Toyota Sienna is the vehicle of choice for soccer moms and rad dads across the nation. If you want to keep your family ferry in good working order, you’ll need to keep your Sienna’s engine topped off with the right amount of oil—6.4 quarts.
The 2010 edition of the Toyota minivan wowed owners with its affordability. With an original starting price of just $24,540, the 2010 Sienna was a real money saver. But, saving money on the sticker price doesn’t make sense if you're constantly paying for repairs. That’s why it’s important to know your Sienna’s oil capacity and to
change your oil
You can find all the info you need about the 2010 Toyota Sienna’s oil capacity in your vehicle’s owner’s manual. But, if you’ve lost your manual, have no fear—we’ve compiled this useful guide with all the 2010 Toyota Sienna oil capacity info you need.

2010 Toyota Sienna engine oil capacity

Let’s answer the big question right off the hop: how much motor oil does a 2010 Toyota Sienna need?
Well, each and every 2010 Sienna is furnished with a 266-horsepower 3.5-liter V6 engine which has an oil capacity of 6.4 quarts or 6.1 liters. But don’t get your engine’s oil capacity confused with its displacement. Engine displacement is the total volume of your engine’s cylinders—that’s what “3.5-liter” describes in “3.5-liter V6 engine.”
Engine displacement and oil capacity are not the same things, and if you only put 3.5 liters of oil in your 2010 Toyota Sienna, it would be well under the required amount of motor oil.

What kind of oil does a 2010 Toyota Sienna need?

The 2010 Toyota Sienna uses
SAE 5W-30 Toyota Genuine Synthetic Motor Oil
, but if you’re having trouble finding that, you can use SAE 10W-30—just be sure to use 5W-30 at your next oil change.
Engine oil has a code that describes the oil’s viscosity—that is, how easily the oil flows. These codes are written as a combination of numbers and letters, ie. 5W-30. 
The first two digits in the code refer to the oil’s cold temperature viscosity, and the lower the first number, the easier the oil will flow when the engine is cool and in cold climates. In fact, the “W” stands for winter—that’s how you know it's the cold temperature viscosity.
The second number indicates the oil’s operating temperature viscosity. The higher the second number, the easier the oil will flow at high temperatures.
SAE is the initialism for the Society of Automotive Engineers, which is the organization responsible for developing these oil viscosity codes.

How often to change the oil on a 2010 Toyota Sienna

Oil changes are an important part of
regular car maintenance
. Toyota recommends changing your 2010 Sienna’s oil every 3,000 to 5,000 miles—about every six months—but synthetic oil can last from 7,500 to 10,000 miles, which means you might be able to go up to a year in between oil changes.
The key is to keep an eye out for signs that it might be time to change your oil, such as:
  • Dark brown or black oil. Healthy motor oil should be amber in color, like liquid honey. 
  • Coarse oil. Bad oil can feel sandy to the touch. Good oil should feel smooth as satin.
  • Strange sounds. If you hear new or loud noises coming from your engine, it might be time to change your oil.
  • Strange smells. New smells can also be a sign of bad oil, particularly if you smell burning oil or smoke.
  • Reduced fuel economy. Bad oil greatly inhibits your engine’s efficiency, so if you find yourself going less time between fill-ups, it might be because your oil is wonky.
These signs can appear anytime, so even if you are within the recommended 3,000 to 5,000-mile interval, you may still need to change your oil.
The 2010 Toyota Sienna comes with an oil life tracking system, and the Maintenance Required Light will come on at the 4,500-mile mark after the last oil change to remind you of the upcoming 5,000-mile recommended oil change interval. But, again, if you notice any of the above symptoms, you may need to change your oil earlier than that.

How to change your oil and oil filter

When it’s finally time to change your Sienna’s oil, you’ll need to gather some materials and a few tools. The job will require a socket wrench, an oil drain pan, a new oil filter, seven quarts of 5W-30 motor oil, and an oil filter wrench.
When you’ve got everything you need, start up your minivan and let the engine warm up for about five minutes to get it to regular operating temperature. Next, shut off the engine, pop the hood, and follow these instructions:
  • Take the oil fill cap off and set it aside.
  • Raise Toyota Sienna with ramps or a car jack, and place the oil drain pan underneath the engine.
  • Remove the oil drain bolt and washer located underneath your van at the bottom of the engine.
  • While the oil drains into the pan, remove the old oil filter and replace it with the new oil filter.
  • When the oil has completely drained, replace the oil drain bolt using a brand-new washer and tighten the bolt to 30 ft-lbs of torque.
  • Fill your engine with 6.4 quarts of fresh 5W-30 motor oil and put the fill cap back on. You still have it, right?
Now, start up your engine and let it run for a minute. While you’re waiting you should check for leaks. If everything looks good, shut off your engine and check your oil level. Top off the oil if needed, and put the fill cap back on once more.
You’re almost done. Now you just have to reset the oil life tracker. To do this turn your vehicle on, but do not start the engine. 
Locate your “trip” or “odometer” button on the dash display and push it to toggle through your dash menu until reaching the odometer display—it should say ODO. Next turn off the vehicle, hold down the trip button, and turn the vehicle back on without starting the engine. Your odometer should show several zeros, and your Maintenance Required Light should disappear.
If the light does not go away, bring your Sienna to your nearest
dealer and have them take a look at it, as the illuminated light may be an indicator of a bigger problem.
After you’ve reset the oil life tracker, pour the old motor oil into a sealable container and take it to your local recycling center. Do not dump the old oil down a drain, toilet, sewer grate, on the ground, or put it in your garbage.
