They will result in urgent repairs that will cost you a lot. 

The oil system is extremely important for the proper functioning of your Toyota Sienna. There are a few crucial components that allow smooth work. Read on and find out more! 


Proper oil  

The oil is crucial for a well functioning engine. It will lubricate the moving Toyota Sienna Parts, as well as cool down the engine and prevent overheating. As the oil does serious work, it will trap a certain amount of debris. When the oil is too dirty, it won’t be able to do its job.  Toyota Siena models require oil changes every 10,000 miles, or once a year.  

If you don’t change the oil, you risk damaging the whole engine. Changing the old dirty oil with brand new is very important. There are different types of engine oils, so you need to make the right choice for your car’s engine. For example, the 3.5L V6 engine in a 2017 Sienna requires 0W-20. Check up with the instructions given by the manufacturer to see about your specific model.  

When you perform an oil change, make sure that you have the needed tools. You don’t want to find out that you are missing an important tool in the middle of the process when you need it the most. Also, keep in mind that you should do research about motor oil disposal. 


Oil filter 

When you change the oil, you will need to change another important part. One of the important functions of oil is cleaning the engine parts. It gathers the debris when circulating around the moving parts. The oil filter is meant to prevent the debris and large particles from circulating again. It will trap all impurities, which will result in a debris buildup. When there is too much debris in the filter, it won’t be able to work proeprly.  

Make sure that you replace the old with new genuine Toyota Sienna oil filters. Keep in mind that this crucial part isn’t too expensive, and it can prevent further damage. There is no reason why not to change the oil filter.  


You are advised to change the filter along with an oil change, however, consult the manual for your specific model. There are various signs by which you can tell that the filter is ready for a change. The low oil pressure is the first indicator, but there are more signs. Check if the engine is overheating, or you hear unusual noises. Also, dirty exhaust can be a sign that the oil is too dirty. The car will be working less efficiently, so e sure to avoid any inconvenience.
