What Are The Signs That Your 2018 Toyota Sienna Needs An Oil Change?
Several signs may indicate the need for an oil change in your 2018 Toyota Sienna, such as:
-
Check Engine or Oil Change Light
The check engine light or oil change light may illuminate the dashboard. This means that the oil life monitoring system has detected that the oil quality or level is low and needs to be replaced.
-
Dark and Dirty Oil
Over time, engine oil can become dirty and darken in color. This is due to the accumulation of contaminants, such as dust, metal particles, and fuel residues. If you check the oil on the dipstick and it appears significantly darker than the fresh amber color, or if it has a gritty texture, it may be an indication that an oil change is necessary.
-
Loud Engine Noise and Knocking
As engine oil ages and becomes less effective, it may fail to provide adequate lubrication to engine components. This can result in increased friction, wear, and heat, which can cause the engine to make loud noises or knock. If you hear unusual sounds from the engine, especially when accelerating or idling, it may be a sign that the oil is too old or low and needs to be changed.
How To Check The Oil Level And Quality Of Your 2018 Toyota Sienna?
Checking the oil level and quality of your 2018 Toyota Sienna is a simple and important task that you can do by yourself. Here are the steps to follow:
- Park your car on a level ground and turn off the engine. Wait for at least five minutes to let the oil settle.
- Open the hood and locate the oil dipstick. It is usually yellow and may be labeled as “OIL”.
- Pull out the dipstick and wipe it clean with a cloth or paper towel. Then, reinsert it fully and pull it out again.
- Check the oil level by looking at the markings on the dipstick. The oil level should be between the minimum and maximum marks. If the oil level is low, you need to add some oil.
- Check the oil quality by looking at the color and consistency of the oil. The oil should be brown or black, and smooth and slippery. If the oil is milky, gritty, or smells like gas, you may have a problem with your engine and should consult a mechanic.
- To add oil, open the oil filler cap on top of the engine and pour the appropriate oil for your car. You can find the recommended oil grade in your owner’s manual or on the oil filler cap. Do not overfill the oil, as this can cause damage to your engine.
- After adding oil, wait for 30 seconds and repeat the dipstick test to check the level again. When you are done, replace the oil filler cap and the dipstick, and close the hood.
