Do I need to change my engine oil right now?
The recommended oil change interval for a Toyota Corolla 12th generation varies depending on several factors, such as driving conditions and the type of oil used. However, Toyota recommends changing the engine oil every 10,000 miles or 12 months, whichever comes first, under normal driving conditions.
It’s important to note that if you drive your Corolla in severe conditions, such as extreme temperatures or dusty environments, you may need to change the oil more frequently. In such cases, Toyota recommends changing the oil every 5,000 miles or six months, whichever comes first.
Step-by-step instructions on how to check the engine oil level
- Park your car on level ground and turn off the engine. Wait a few minutes to allow the engine oil to settle in the oil pan.
- Open the hood of your car and locate the engine oil dipstick. It should be located on the front side of the engine, near the front of the car.
- Remove the dipstick from the engine by pulling it straight out.
- Use a clean rag or paper towel to wipe off the dipstick completely.
- Reinsert the dipstick all the way back into the engine, making sure it’s fully seated.
- Remove the dipstick again and look at the oil level. The dipstick will have two marks labeled “Low” and “Full”. The oil level should be between these two marks.
- If the oil level is below the “Low” mark, you’ll need to add more oil. If it’s above the “Full” mark, you may have too much oil in the engine, which can be harmful.
- If you need to add oil, remove the oil filler cap, which should be located on the top of the engine. Add the recommended type of oil slowly, checking the oil level frequently using the dipstick until it reaches the “Full” mark.
- After adding oil, replace the oil filler cap and recheck the oil level to ensure it’s at the correct level.
- Finally, replace the dipstick back into the engine and close the hood.
That’s it! Checking the engine oil level is an essential part of car maintenance that can help ensure your car’s engine runs smoothly and lasts a long time.
Express test for checking the quality of engine oil using a piece of paper
A rapid engine oil quality test using a piece of paper is called the “blotter spot test,” and it can give you a quick assessment of the oil’s condition.
- Take a white, unlined piece of paper and fold it in half, making a crease down the center.
- Open the paper back up and place a few drops of engine oil on the center of the paper, just above the crease.
- Fold the paper in half again, this time pressing down on the oil to spread it out evenly.
- Open the paper back up and observe the oil spot. Look for the following characteristics:
- Color: If the oil appears dark and opaque, it may be contaminated with dirt or debris. Clean engine oil should have a clear, amber color.
- Consistency: If the oil feels sticky or gummy to the touch, it may be contaminated with fuel or other substances. Clean engine oil should have a smooth, consistent texture.
- Saturation: If the oil has soaked through the paper and spread out significantly, it may be thin or degraded. Clean engine oil should form a defined circle on the paper without soaking through.
- Debris: If there are any particles or debris present in the oil spot, it may indicate a problem with the engine, such as metal shavings or sludge.
