Vehicle: 2018 Hyundai Elantra SE

Hey everyone,

I'm looking to do my first DIY oil change on my 2018 Hyundai Elantra with the 2.0L engine. I've heard different things about oil types and weights, so I'm a bit confused. What's the recommended oil type and viscosity for this specific engine?

Also, any tips or tricks for a first-timer? What kind of oil filter should I get? I want to make sure I'm using the right stuff to keep my Elantra running smoothly. Thanks in advance for the help!

Hello Chris P.,

Great initiative on tackling your own oil change! It's a fundamental maintenance task that can save you money and give you peace of mind.

For your 2018 Hyundai Elantra with the 2.0L engine, the manufacturer generally recommends:

  1. Oil Type: Full Synthetic or Synthetic Blend engine oil.
  2. Viscosity: SAE 5W-20 or 5W-30, depending on your climate and specific engine variant. Always check your owner's manual for the most precise recommendation for your vehicle's trim and region.
  3. API Specification: Look for API SN PLUS or SP rating, which indicates protection against low-speed pre-ignition (LSPI).

DIY Oil Change Tips:

  • Tools: You'll need a wrench for the drain plug, an oil filter wrench, a drain pan, a funnel, and a torque wrench for proper tightening.
  • Filter: Use a high-quality oil filter. OEM Hyundai filters are always a safe bet, but reputable aftermarket brands like Wix, Mann, or Bosch are also good choices. Ensure it's specifically for your Elantra's engine.
  • Procedure:
    1. Warm up the engine slightly (5-10 minutes) to help the oil flow better.
    2. Safely lift and support the front of the car with jack stands.
    3. Locate the drain plug and oil filter. Place your drain pan underneath.
    4. Remove the drain plug and let all the old oil drain out. Replace the crush washer on the drain plug.
    5. Remove the old oil filter. Apply a thin film of new oil to the rubber gasket of the new filter before installing.
    6. Hand-tighten the new filter until snug, then give it an additional 1/2 to 3/4 turn. Consult your filter's instructions or owner's manual for specific torque.
    7. Reinstall the drain plug and torque it to specification (usually around 25-30 ft-lbs, but verify for your model).
    8. Lower the car and fill the engine with the recommended amount of new oil (typically around 4.2-4.5 quarts for the 2.0L, but check your manual).
    9. Start the engine, let it run for a minute, then shut it off. Check for leaks and verify the oil level on the dipstick.

When to See a Shop: If you're uncomfortable with any step, don't have the right tools, or encounter unexpected issues like stripped bolts, it's always best to consult a professional mechanic.
