Why Should You Check the Oil Level?

By checking your oil level you can keep your car’s engine in good shape and avoid unnecessary breakdowns and costly repairs.

Monitoring and checking your oil level will greatly improve the engine’s performance and reduce the risk of a breakdown. Oil reduces friction in the engine to keep all parts moving smoothly and is essential to the running of the engine. Too little oil in your engine will cause the engine to perform poorly and take damage.

How Often Should You Check the Oil Level?

You want to check your car’s oil at least once a month. Checking the engine oil level in your car is a simple process.

4 Easy Steps to Checking Your Engine Oil Level

1. Park your vehicle on a level street.

Parking on a level street is important as your engine oil should be level in its container. After parking, wait at least 10-15 minutes or until your engine has cooled down before you begin checking your oil level. If you check any fluid while your engine is still hot, you risk severe burns.

2. Locate the oil dipstick in your car.

You can find the oil dipstick by looking for a yellow ring on or next to your oil tank. The location of the oil dipstick will be different if you are driving a rear-wheel drive compared to a front-wheel-drive vehicle, but the yellow ring will look the same.

3. Pull out the oil dipstick and wipe it off with a clean rag.

You need to wipe the oil dipstick off before doing the reading as oil can splash onto the dipstick as you drive, making the reading inaccurate. Once wiped off you can re-insert the oil dipstick back into the pipe to get an accurate reading.

4. Re-insert the oil dipstick and pull it out again.

Insert the oil dipstick back into the pipe and then pull it out again. Note how high the oil film reaches on the dipstick. There are markings on the oil dipstick that indicate when you need to add more oil – the oil film should reach above the indentation or MIN part in the oil dipstick or you need to add more oil.

The picture below shows an oil dipstick. You can see the MIN indentation, the MAX indentation, and the CURRENT OIL LEVEL. The oil level in your engine should be in between the MIN and MAX markings.

How To Fill Up or Change Engine Oil

When you do end up having to fill up your oil level, look for the lid with the “engine oil” icon. It should be on or next to the engine. Then re-fill gently and apply the same method that you used when checking the oil level to determine when you have filled enough.

If your engine oil is contaminated and has to be changed, you can empty the engine oil through a drain plug on the bottom of the engine. To reach the plug you may need to crawl under your car.

What Does Contaminated Oil Smell Like?

You also want to smell the oil to make sure it isn’t contaminated by gasoline. If the oil smells of gasoline it’s contaminated and should be changed.
