What is the 2021 Toyota Sienna Oil Type and Capacity?

How often does a Toyota Sienna need an oil change?

Toyota recommends that you change your 2021 Sienna’s oil with 0W-16 fully synthetic oil every 10,000 miles or 12 months. However, you may need to change your oil sooner depending on your driving habits, car conditions, and several other factors.

Over time, your engine oil will degrade and lose its effectiveness. When this happens, the engine’s ability to lubricate and absorb heat is compromised. Regular oil changes in your Sienna will help keep the parts lubricated and also keep it running at its peak. 

Also, using the right oil and viscosity in your Sienna determines the engine’s longevity. Synthetic oils are recommended for your 2021 Sienna because they have a higher viscosity index, and better oxidation stability and they increase your engine’s performance.

What is the difference between 0W-16 and 0W-20 engine oil?

Both 0W-16 and 0W-20 are low-viscosity oils that have been significantly optimized for fuel economy. However, they have a few notable differences, some of which include:

1. Fuel efficiency

As stated earlier, both 0W-16 and 0W-20 motor oils are heavily optimized for fuel efficiency. However, if you observe their weight closely, you will notice 0W-16 is slightly thinner than 0W-20.  Since it is thinner, it does better at exchanging heat because the oil flows faster.

So, despite 0W-20 being a good choice for fuel economy, 0W-16 does better when it comes to fuel economy.

2. Temperatures

Both 0W-16 and 0W-20 are suitable for cooler temperatures because they flow easily to lubricate vital engine parts and provide excellent cold-start performance. However, because 0w-16 is a slightly thinner oil than 0w-20, it performs better during cold starts.

This means that 0W-16 oils will perform better than 0W-20 during the winter or extremely cold temperatures. While 0W-20 will lubricate your engine better during summer or hot temperatures.

3. Recommendations

0W-16 and 0W-20 motor oils are generally recommended for modern gasoline and petroleum engine vehicles, especially in extremely cold regions.

However, with the increasing global demand for engine fuel economy, more European vehicles are beginning to tilt towards thinner oils like 0w-16. 0W-16 also comes highly recommended for hybrid vehicles.

4. Pricing

Both 0W-16 and 0W-20 are expensive but 0W-16 is more expensive. This is obviously because of their viscosity and excellent fuel efficiency.

How can you change your 2021 Sienna’s oil in your garage?

 To change the oil in  your 2021 Toyota Sienna, get the appropriate oil ad tools, then follow the steps below:

Step 1: Warm up your engine to an operating temperature

Step 2: Drive your car up ramps to raise so that the front end of the car is high enough for you to get under.

Step 3: Take off the engine oil fill cap and set aside

Step 4: Detach the access panel from the skid plate with a screwdriver to get to the oil pan drain plug.

Step 5: Use a 14mm socket or wrench to slide the drain pan under the drain plug 

Step 6: When you have fully drained the oil, replace and tighten the drain plug

Step 7: Take out the oil filter.

Step 8: Lubricate the new oil filter o-ring with a fingertip dipped in oil.

Step 9: Install and tighten the new oil filter.

Step 10: Re-install the skid plate access panel

Step 11: Fill up your engine with 4.5 quarts of fresh engine oil, the replace engine oil fill cap

Step 12: Start the engine and take your car off of the ramps

Step 13: Park your car on a level surface, then check the engine oil level on the dipstick. Adjust it if you need to.

Step 14: Bravo, you did it!

Why is it best to change the oil with a warm engine?

It is best to change your oil with a warm engine because the oil viscosity is thinner, so it drains out of the engine faster and completely.

Contaminants are more likely to stay suspended in hot engine oil than in cold engine oil. With this, the chances are that they will be flushed out of the engine during the draining procedure.

However, it is not advisable to change your oil when the engine is red-hot. Let the engine sit for an hour or half before starting the draining process. Also, ensure that you wear protective gloves to minimize the chances of getting burnt.  

Can I use the same oil filter twice?

No, you should not use the same oil filter twice. In fact, Toyota recommends that you change your Sienna’s oil filter each time you change your engine oil.

Your Sienna’s engine requires a substantial amount of fresh oil to function effectively. If you don’t change your oil filter regularly, it can become severely clogged. A clogged filter distorts oil flow in the engine and hinders proper lubrication of the engine. This could result in poor engine performance, overheating, and in worse cases, engine damage. 

Does changing engine oil increase horsepower?

Changing your engine oil may not necessarily increase your horsepower but keeping dirty or old oil in your engine will decrease it. Old oil not only lowers your horsepower but also the efficiency and mileage of your car. This may eventually shorten the life of your engine. 

Ensure that you change your oil in line with the instructions in your owner’s manual.
