The 2006 Toyota Sienna has an oil capacity of 5 quarts (4.7 liters).
The 2006 Toyota Sienna is a long-lasting van, with the space, power, and practicality to satisfy most modern families. Although it’s gotten a bit older, a 2006 Sienna could still run smoothly for many years if it’s taken care of properly—starting with regular oil changes.
A V6 vehicle requires a bit more engine oil than a standard sedan, so you can expect to spend a bit more on
oil changes
with your Toyota Sienna. But this is a relatively easy service to perform yourself if you want to save some money by getting your hands dirty.Here’s a quick guide to the 2006 Toyota Sienna’s engine oil capacity.

The oil capacity on your 2006 Toyota Sienna is about the same as most vans.
If you are using a new fuel filter, this car takes 5 quarts (4.7 liters) of engine oil.
The size of the six-cylinder engine on the Sienna means that you can expect to buy more oil for this van than for a typical four-cylinder sedan. In other words, your cost of ownership—including oil changes—for the Sienna may be slightly higher because of its larger engine oil capacity.
What kind of oil does a 2006 Toyota Sienna need?
Toyota states that the 2006 Toyota Sienna is supposed to use 5W-30 engine oil. Engine oil ratings are highly specific, and using the incorrect viscosity grade could cause serious damage to your engine
Need a quick refresher on engine oil ratings and what they mean? We’ve got you covered.
That 5W-30 rating is a shorthand for describing the viscosity of the oil at different operating temperatures. “W” stands for winter, and the 5 and 30 signify how thick or thin the oil becomes at different temperatures.
The “5W” means that your van can start up in relatively cold temperatures. “30” refers to the viscosity when the Sienna is running at peak operating temperature. High viscosity is typically preferred for vehicles that move heavy loads.
The brand is less important than the rating when it comes to engine oil. As long as you select a 5W-30 engine oil from a reputable manufacturer—you should notice an API certification seal on its container—it should perform well in your Toyota Sienna.
Remember, you can always check your owner’s manual to learn more about how to change your oil or explore your Sienna’s oil capacity and other specifications.
How often to change oil on a 2006 Toyota Sienna
Toyota recommends an oil change for the Toyota Sienna every 5,000 miles. When using synthetic oil, you may be able to extend that range between 7,500 and 10,000 miles, but it depends on factors like what condition your engine is in and what kinds of driving conditions are typical for you.
To get the timing of your engine oil change right, you should get in the habit of checking your engine oil for quality and amount. This should be a monthly event. It’s easy to use your dipstick and quickly assess the level and texture of your engine oil.
Here are a few signs your van might be due for an oil change:
- Dark color: Clean motor oil is amber-colored, while dirty oil will be dark brown or black as it collects debris
- Gritty texture: Clean motor oil is smooth
- Odd noises: Low oil or a leak could lead to clanking sounds, meaning components aren’t getting properly lubricated
- Smoky smells: If you smell something burning, get your oil checked
Reduced performance can be yet another signifier that you need an oil change.
How to change your oil and oil filter
Car ownership can be expensive! Luckily, some
maintenance tasks
are easy to perform yourself—and doing so will save you money. The cost of an oil change is easily more than $100 for the Toyota Sienna. So, the first thing you’ll need for your 2006 Toyota Sienna’s oil change is five quarts of 5W-30 engine oil—but that’s not all.
To perform an oil change and swap out the filter, you’ll also need: a new oil filter, a funnel, a 14mm socket, a torque wrench, an oil filter wrench, clean rags, a drain pan, gloves, and eye protection. You’ll need to park the car somewhere level and secure. If you decide to use jacks for easier access, remember to keep best safety practices in mind.
When you’re ready, you can start by running the van for a few minutes to get the oil warmed up, which will help it drain more easily. Then, turn off the engine, pop the hood, and you’re ready to change your Toyota Sienna’s oil.
Here are the steps to change the oil on a 2006 Toyota Sienna:
- Remove the oil fill cap
- Place a drain pan beneath the engine to catch the old engine oil
- Remove the oil drain bolt
- Allow the old oil to drain out
- Install the new oil filter
- Replace the drain bolt to the appropriate torque specifications
- Use a funnel to add new oil
- Wipe up any spills and replace the oil fill cap
You’re almost done! Look for any visible leaks. If you don’t see any, run the van for a few minutes. After the engine has cooled off again, check the level with the dipstick to confirm that you have added enough oil. If not, add more as necessary.
The last step is to properly dispose of your old engine oil. Do not pour it down the drain or dump it into the garbage! Instead, take it to a recycling center in your area that accepts it. Some auto shops will accept used motor oil for recycling as well.
