Do I need to urgently change the oil right now?

What is the frequency (interval) of changing engine oil?

The recommended frequency of changing the engine oil in a Toyota Highlander depends on the model year, the type of engine, and the driving conditions. In general, Toyota recommends changing the engine oil every 10,000 miles or 12 months, whichever comes first, for newer models with synthetic oil. For older models or those with conventional oil, Toyota recommends changing the oil every 5,000 miles or 6 months.

However, there are some situations where the recommended oil change frequency may change. For example, if the Highlander is driven in severe conditions, such as in extreme heat or cold, in dusty or sandy environments, or for frequent short trips, Toyota recommends more frequent oil changes. In such cases, the oil should be changed every 5,000 miles or 6 months for synthetic oil or every 3,000 miles or 3 months for conventional oil.

The spacing between oil changes can also be affected by the type of oil used. Synthetic oil is designed to last longer than conventional oil and can often go longer between oil changes. If the Highlander uses synthetic oil, the recommended oil change frequency may be longer than if it uses conventional oil.

How to check the engine oil level?

To check the engine oil level in a Toyota Highlander, follow these steps:

1. Park the vehicle on level ground and turn off the engine. Wait a few minutes to allow the oil to settle in the oil pan.
2. Open the hood and locate the engine oil dipstick. It is usually labeled and has a yellow handle for easy identification.
3. Pull the dipstick out of the engine and wipe it clean with a rag or paper towel.
4. Reinsert the dipstick into the engine all the way in, and then pull it out again.
5. Check the oil level on the dipstick. The oil level should be between the two marks or within the crosshatched area on the dipstick. If the oil level is below the low mark, it is time to add more oil.

If the oil level is low, follow these steps:

1. Add oil as needed, using the oil recommended in the owner’s manual.
2. Start the engine and let it run for a few minutes.
3. Turn off the engine and wait a few minutes for the oil to settle.
4. Check the oil level again with the dipstick to ensure that the oil level is now within the recommended range.
5. If the oil level is still low, repeat the process of adding oil until the level is correct.

Visual (express) assessment of the condition of engine oil

To understand the current state of engine oil by visual inspection, follow these steps:

1. Open the hood of the vehicle and locate the engine oil dipstick.
2. Pull out the dipstick and inspect the color and consistency of the oil on the dipstick.
3. Clean the dipstick with a rag or paper towel, and then reinsert it into the engine. Pull the dipstick out again and check the oil level.

When inspecting the oil on the dipstick, here are some things to look for:

1. Color: Fresh engine oil is typically amber or light brown in color. As the oil ages and becomes contaminated with dirt and debris, it can darken and turn black. Milky or foamy oil can indicate the presence of coolant in the oil, which can be a sign of engine problems.
2. Consistency: The oil should be smooth and consistent, without any lumps or particles. If the oil feels gritty or has debris in it, this can indicate that it is time for an oil change or that there is a problem with the engine.

To perform a quick visual inspection of the engine oil using a piece of paper, follow these steps:

1. Take a white piece of paper and place a few drops of engine oil on it.
2. Wait a few minutes for the oil to spread and settle on the paper.
3. Observe the color and consistency of the oil on the paper.

When performing a visual inspection of engine oil using a piece of paper, here are some things to look for:

1. Color: Fresh engine oil will appear as a light or transparent spot on the paper, while dirty or contaminated oil will appear darker and may have streaks or spots of debris.
2. Consistency: Engine oil that has thinned out or become contaminated may spread out more on the paper, while fresh oil will remain more contained.

Additionally, warming up the engine will help to suspend any contaminants in the oil, making them easier to remove.

To properly warm up the engine before changing the oil, you should start the car and let it idle for a few minutes, or take it for a short drive around the block. This will help to raise the temperature of the engine and the oil, making it easier to drain. However, it’s important not to overheat the engine, so you should avoid revving the engine or driving aggressively while it’s warming up.

After the engine has been warmed up, turn it off and allow it to cool down for a few minutes before you begin draining the oil. This will allow the oil to settle in the oil pan and reduce the risk of getting burned by hot oil or components. Once the engine has cooled down enough to touch, locate the oil drain plug and oil filter and proceed with the oil change as you normally would.
