2018 Elantra Oil Change - What Oil Type and DIY Tips?

0

Ashley M. · rep 0 · May 22, 3:02 AM · 1 replies · solved · Question

Hey everyone, I've got a 2018 Hyundai Elantra SE with about 60,000 miles on it. I usually take it to the dealership for oil changes, but I'm looking to start doing them myself to save some money and learn a bit more about my car.

I'm a bit confused about the exact oil type and viscosity I should be using. The owner's manual mentions a few options, but I want to make sure I'm getting the best synthetic oil for its age and mileage.

Also, any tips or tricks for a first-timer doing an oil change on this specific model? What tools will I need, and are there any common pitfalls I should watch out for? Thanks in advance for the help!

Summary: For 2018 Elantra Oil Change - What Oil Type and DIY Tips?, work through these steps on your 2016+ vehicle:

  1. Confirm the symptom — note when it happens (cold start, highway, after fuel fill, etc.).
  2. Scan codes — save all pending/stored DTCs; don't clear until you've recorded them.
  3. Check TSBs & recalls — look up your VIN for open campaigns and known fixes.
  4. Inspect the obvious — related fuses, connectors, fluid level, and recent repairs.
  5. Test the common fix — follow model-specific service procedures; one change at a time.
  6. Escalate if needed — burning smell, no brakes, overheating, or stalling in traffic → shop visit.
