Hyundai Elantra 1.8L Engine
Motor Oil Filler Cap
Turn Counter Clockwise
This automotive maintenance "how-to" guide was specifically written to assist owners of the 5th generation (2011, 2012 & 2013, 2014, 2015 & 2016) Hyundai Elantra in changing the motor oil and replacing the oil filter on the 1.8 liter Nu MPI inline four cylinder engine.

Owners of other similar Hyundai or Kia vehicles equipped with a 1.8L or 2.0L "Nu" engine or the 1.6L "Gamma" engine such as the Optima (K5) Hybrid, Soul, i40, Accent, i35 and Veloster may also find these DIY instructions to be helpful.

The tools or items needed to complete this oil change procedure include 5 quarts of new SAE 5W-20 oil, a new oil filter, a floor jack, jack stands, a 17mm socket with ratcheting wrench, a used oil catch container and an automotive funnel.

Some compatible oil filters with their part numbers include the following: Purolator PL14459, Mobil1 M1-104, Bosch D3312, K&N HP-1004, Fram PH9688, and ACDelco # PF1127.

Drain Bolt, Oil Pan & Filter
17mm Oil Drain Bolt
Turn Bolt Counter Clockwise
The first few steps are to turn on the engine, allow it to warm up for a few minutes, and then turn it off. Warming up the engine will help suspend any contaminants within the old oil and also allow it to flow out more quickly.

Then engage the parking brake and chock the rear wheels to prevent the vehicle from moving.

Twist the engine oil filler cap counter clockwise until it can be removed and set it aside in a safe place.

Removing the oil filler cap will help prevent a vacuum from forming and allow the old oil to drain out quickly.

Next raise the front passenger side of the vehicle with a floor jack and securely support it with two jack stands.

Slide under the front passenger area of the engine with a used oil catch container, a 17mm socket and a ratcheting wrench.

Be careful when removing the drain bolt since the old oil may be hot enough to cause burns depending on how long you warmed up the engine.

Locate the 17mm oil drain bolt at the back edge of the oil pan facing the rear of the vehicle.

Slide the used oil catch container to just below the oil drain bolt and remove it with the 17mm socket by rotating it counter clockwise.

Allow the old oil to drain out for at least a few minutes.


Drain Out Old Motor Oil
Twist Off Old Oil Filter
Dip Finger In New Oil
Once the old motor oil has drained out for a few minutes, replace the oil drain bolt and tighten to it just past hand tight or to about 20-25 ft lbs of torque.

Move the used oil catch container to below the old oil filter and then twist off the old filter by turning it counter clockwise.

Allow the oil to drain from the oil filter receptacle for a minute or two.

Double check that the rubber o-ring gasket from the old filter isn't still stuck to the engine.

I recommend buying the Mobil1 M1-104 oil filter since it has excellent reviews on Amazon.

Dip your pinky finger into some new SAE 5W-20 motor oil and run it around the rubber o-ring gasket on the new oil filter to lubricate it.

Lubricating the oil filter gasket will help it form a better seal, prevent leaks and also make it easier to remove at the next oil change.

Lubricate Filter O-Ring
Tighten Oil Drain Bolt
Twist On New Oil Filter
Twist on the new oil filter by hand in the clockwise direction to about 2/3 to 3/4 turn past hand tight.

Do not use an oil filter wrench to tighten the new oil filter and do not over tighten the filter.

Double check that both the oil drain bolt and new oil filter are properly tightened before sliding out from underneath the vehicle.

Be sure to remove the used oil catch container and any tools from beneath the car.

Lower Car From Jack Stands
Insert Automotive Funnel
Pour In New 5W-20 Oil
Gently lower the vehicle from the jack stands by using the floor jack.

Insert the automotive funnel into the oil filler hole at the rear left of the engine cover. Pour in about 4 quarts of the engine's 4.23 U.S. quart (4.0 liter) total motor oil engine capacity.

Run the engine for a few minutes, turn it off, and allow the oil to drain back to the oil pan for a few minutes.

Pull out the yellow handled engine oil level dipstick from the center of the engine cover. Wipe it off with a paper towel or shop rag, re-insert it all the way down, and pull it back out again.

Slowly add more oil and re-check the level on the dipstick until it reaches the "F" (full) line near the top of the flattened part of the dipstick.

You may not need to pour in the entire 4.23 U.S. quarts of new SAE 5W-20 oil to reach the correct level depending on how long you allowed the old oil to drain out.

Engine Oil Dipstick
Check Level On Dip Stick
Replace Oil Filler Cap
Once the oil level is correct, re-insert the oil filler cap and tighten it by turning it clockwise until it is snug.

Be sure to check the oil level on the dipstick a few times over the next week and examine your driveway or garage for oil spots that may indicate a leak from the oil drain bolt or the oil filter.

Also, don't forget to record the mileage and oil change details in your car's service record book.
