An inability to easily read your engine oil dipstick would mean that you can’t accurately keep track of the quantity of oil in your engine.
Here are some of the reasons why your engine oil dipstick is hard to read and what you can do to resolve it:
1. Dirty or Worn Dipstick
One of the most common reasons the engine oil dipstick may be hard to read is that it is dirty or worn out. Over time, the dipstick can become coated with oil, dirt, and debris, making it difficult to read the markings.
Additionally, the dipstick may wear out over time, causing the markings to become faint or even disappear. In such cases, you may need to replace the dipstick to make it easier to read.
2. Dirty or Contaminated Oil
Another reason the dipstick may be hard to read is that the oil in the engine is dirty or contaminated. Old or contaminated oil can become thick and sticky, making it difficult to get an accurate reading.
The oil may also be too dark, making it hard to see the oil level on the dipstick. Changing the oil, filtering, and starting fresh with clean oil are best in such cases.
3. Engine Design
The engine’s design can also make it hard to read the dipstick. Some engines have a narrow, twisting dipstick tube that can make inserting and removing the dipstick hard.
This can make it difficult to get a good reading, especially if the oil level is low. Other engines have dipsticks in hard-to-reach areas, making it challenging to get a good reading.
4. Improper Dipstick Insertion
Improper dipstick insertion can also make it hard to read. If the dipstick is not inserted properly, it may not accurately read the oil level.
For instance, if the dipstick is not pushed in or too far, it may not show the correct oil level. Therefore, following the manufacturer’s instructions on inserting the dipstick correctly is essential.
5. Low Oil Level
A low oil level can make it hard to read the dipstick. If the oil level is too low, the dipstick may not show any oil on it, making it appear as if the oil level is empty. Adding more oil to the engine is essential in such cases to bring it up to the proper level.
6. Bent or Damaged Dipstick
Sometimes, the dipstick may get bent or damaged due to accidental mishandling or manufacturing defects. A bent or damaged dipstick may not slide easily into the tube or give inaccurate readings. In such cases, replacing the dipstick with a new one is best.
7. Varying Temperatures
Another factor that can affect the accuracy of the dipstick reading is the engine’s temperature. The oil expands when the engine is hot, causing the level to rise on the dipstick.
Similarly, the oil contracts when the engine is cold, causing the level to drop. Therefore, it’s essential to check the oil level when the engine is at operating temperature or according to the manufacturer’s recommendations.
8. Improper Dipstick Cleaning
Improper cleaning of the dipstick can also make it hard to read. Using a dirty cloth or not cleaning the dipstick properly can cause dirt and debris to accumulate on the dipstick, making it difficult to read the markings. It’s best to clean the dipstick with a lint-free cloth or a paper towel before taking the reading.
9. Improper Storage of the Dipstick
Improper storage of the dipstick can also cause it to become hard to read. Storing the dipstick in a dirty or dusty environment can cause dirt and debris to accumulate on it, making it difficult to read the markings. Therefore, storing the dipstick in a clean and dry place is essential.
How to Fix Issues with an Engine Oil Dipstick Being Hard to Read
1. Clean the Dipstick
If the dipstick is dirty or has debris, reading the oil level accurately can be challenging. To clean the dipstick, use a clean, lint-free cloth or paper towel to wipe it down thoroughly. Remove all the debris and dirt from the dipstick before reinserting it into the tube.
2. Replace the Dipstick
If the dipstick is damaged or bent, replacing it with a new one is best. You can purchase a replacement dipstick from an auto parts store or online retailer. Check your car’s make and model to ensure you purchase the correct dipstick.
3. Check the Oil Level at the Right Time
The best time to check your engine oil level is when the engine is warm or hot and the car is parked on a level surface. If you check the oil level when the engine is cold, the level may not be accurate, and the dipstick may be hard to read.
4. Use a Dipstick Guide
If you’re having trouble reading the markings on the dipstick, you can use a dipstick guide to make the process easier. A dipstick guide is a tool that attaches to the dipstick and provides a clear visual indication of the oil level. You can purchase a dipstick guide from an auto parts store or online retailer.
5. Check the Owner’s Manual
If you still have trouble reading the dipstick, consult your car’s owner’s manual for guidance. The manual may provide specific instructions on how to read the dipstick for your car’s make and model.
Consequences of Not Being Able to Read the Dipstick
1. Engine Damage
If the oil level in the engine is too low, it can cause serious damage to the engine. The engine oil lubricates the engine’s moving parts and keeps them from overheating and causing friction. The engine can seize up without enough oil, resulting in expensive repairs or replacement.
2. Reduced Fuel Economy
Low oil levels can also lead to reduced fuel economy. The engine has to work harder to compensate for the lack of lubrication, which can cause it to consume more fuel. This can result in higher fuel costs and reduce the car’s efficiency.
3. Higher Emissions
Low oil levels can also cause higher emissions. When the engine is not running efficiently, it can produce more pollutants, such as carbon monoxide and nitrogen oxide, which can harm the environment.
4. Engine Knocking
Low oil levels can also cause engine knocking, which is a sound that indicates that the engine is not running correctly. Engine knocking is a sign of severe engine damage, and if left unchecked, it can cause further damage to the engine.
5. Safety Hazard
Not being able to read the dipstick accurately can also be a safety hazard. If the engine oil level is too low, it can cause the engine to stall or fail, leading to potentially dangerous situations, such as accidents or breakdowns.
How to Read an Oil Dipstick Correctly
1. Locate the Dipstick
Before anything else, you need to locate the oil dipstick in your car’s engine. It’s typically a long, thin metal rod with a handle, usually located on the side or front of the engine. Refer to your car’s owner’s manual for the exact location.
2. Park the Car on a Level Surface
You need to park your car on a level surface to get an accurate reading. A flat driveway or parking lot would be ideal. If the car is on an incline, the oil may not settle evenly, and you may not get an accurate reading.
3. Turn Off the Engine and Wait
Once you have parked your car, turn off the engine and wait for it to cool down for a few minutes. This allows the oil to settle back into the pan, giving you a more accurate reading.
4. Pull the Dipstick Out
Remove the dipstick from the tube and clean it with a lint-free cloth or paper towel. Remove all the dirt and debris from the dipstick to get an accurate reading.
5. Reinsert the Dipstick
Insert the dipstick back into the tube, ensuring it’s fully seated. Then, pull it out again, and this time, observe the oil level on the dipstick.
6. Read the Oil Level
The dipstick has markings on it indicating the oil level. Look for the “FULL” mark and the “ADD” mark. The oil level should be between these two marks. If the oil level is below the “ADD” mark, it’s time to add more oil.
7. Check the Oil Condition
While you have the dipstick out, look at the oil’s color and consistency. The oil should be clear and not too thick or thin. If the oil is dark or dirty, it’s time for an oil change.
8. Add Oil If Necessary
If the oil level is below the “ADD” mark, add more oil to your car’s engine. Refer to your car’s owner’s manual for the oil type and how to add it.
