How to Check and Add Engine Oil 

This will show you how to properly check and add engine oil for a Hyundai Sonata. However, this procedure applies to other models as well. 

  1. Open the driver's side door and locate the hood release handle. open drivers door (Typically along with the left side kick panel or under the dash below the steering wheel)
  2. Pull the release handle until you hear a pop. This will tell you that the hood is released. open hood TIP: there should be tension on the release handle from the hood cable for the hood release to be pulled. If you cannot feel any tension and you do not hear a pop when you pull the release handle, you may be able to take a pair of needle-nose pliers and pull on the cable itself just behind the hood release handle. If this does not pop your hood, you may need your hood cable replaced.
  3. Once the hood is released, walk over to the front of the vehicle and feel for the second hood release handle to raise your hood. Once the hood is raised, there may be hood shocks holding your hood up and out of the way. Or there may be a prop rod you will need to place on the underside of the hood. If the hood goes up with little effort and does not try to slam down when you begin to pull your hand away, you most likely have hood shocks. If your hood does not stay up on its own, there is a prop rod that holds your hood up. this can be easily located by checking the perimeters of your engine bay. Usually along the front, just about the grille, or along with one of the fenders.  hyundai engine


  4. Now you can locate your engine oil dipstickoil dipstick on hyundai sonata In this case, the oil dipstick is orange and right in front of the engine. Place your hand on top of the dipstick and pull straight up until the dipstick is completely removed to prevent bending the dipstick.  
  5. Now that the dipstick is out, wipe the oil off the dipstick and reinsert into the dipstick hole and remove it again for a more accurate oil level reading. 
  6. While still holding the dipstick horizontal to the ground, check the level by seeing where the oil is relative to the indicator dots. The dot further up the dipstick towards the top indicates that the oil is full and does not need to be filled. However, the dot towards the end of the dipstick indicates that the oil is at the bottom of the operating range, and you will need to refill ASAP.  TIP: If your oil is between the two dots, your engine oil is at a normal range. However, adding oil is recommended, so the reading is near the top indicator dot.  
  7. If you found that you need to add engine oil, look for the engine oil fill cap at the top of your engine. This is typically indicated with the word "oil" or with the engine oil viscosity printed on the cap itself, such as 5W-30. check hyundai engine oil level


  8. Turn counterclockwise until the cap is free, and you can place it aside. 
  9. Now that you have purchased the correct oil viscosity and you know where to add the oil, place the engine oil funnel in the fill hole and add the necessary amount of oil to achieve optimum engine oil level. 
  10. Remove the engine oil funnel, replace the oil fill cap and confirm your engine oil level reading on the dipstick. Once engine oil fill level is achieved, replace engine oil dipstick. Wipe any dripped or spilled engine oil on your engine bay clean, lower prop rod, and or close hood securely. 

Common Causes

What can cause Hyundai oil light to come on? 

  • External and Internal engine oil leaks 
  • Incorrect oil viscosity causing the oil to "burn" off and out the exhaust
  • Going too long between oil changes
  • Minor/Major engine damage (i.e., bad PCV valve, blown head gasket) 

Can I drive with low engine oil?

This is not recommended. Driving with low engine oil will cause more damage to the internal components of your engine over time. Also, proper engine cooling and performance will suffer as a result. 

What type of oil should I put in my car?

You should always add the OEM recommended oil viscosity to your vehicle's engine. (i.e 5w30, 10w30) you can consult your owner's manual for this information. If you do not have or cannot locate your owner's manual, a quick google search will point you in the right direction. 

Where can I get engine oil? 

You can purchase engine oil at many local retailers, including box stores like Wal-mart. However, if you are not sure what to get, auto part stores are an excellent resource. They have OEM recommendation catalogs to help you find the right brand, viscosity, and quantity you require. 

How much engine oil should I add?

In this video, the engine oil level is indicated by two dots towards the end of the dipstick. The dot towards the top of the dipstick is the full indicator, and the one towards the end of the dipstick is the filled dot. If your oil level is at the filled dot, typically, your car's engine requires an entire quart of oil.

However, always start with a half quart, check the reading again and add more if necessary to prevent overfilling. If your engine oil level reading is between the two indicator dots, your engine oil level is in operating range but is probably low a half quart. Add half a quart and re-check your engine oil reading by reinserting the dipstick and pulling it back out. 

TIP: To confirm your hood is closed securely, pull up on the hood once you believe it is latched. At this time, your hood should not "pop" back up and will remain down until you pull the release on the inside of the car again.

Also, if you still want added peace of mind, many vehicles have a warning light on the dash indicating if the hood is open. Start your car and confirm that there is no warning light indicating your hood is open, and you are good to go!
