Complete Oil Specifications

Kia’s European owner’s manual for the 2023 Ceed with the Smartstream G1.0 T-GDi engine calls for full synthetic SAE 0W-20 rated API SN PLUS/SP or ILSAC GF-6 (for markets outside the Middle East and North African countries it lists separately). Engine oil drain-and-refill volume is 3.6 L (3.8 US qt).

When to Change the Oil

Under the manual’s normal maintenance schedule for gasoline engines in Europe (except Russia), replace the engine oil and oil filter every 15,000 km (10,000 miles) or 12 months, whichever comes first. Severe driving conditions, or using oil below the recommended specification, call for more frequent changes on the severe-maintenance schedule.

What We Couldn’t Confirm

  • Whether 3.6 L includes the filter. Kia labels it “drain and refill”.
  • Severe-usage interval figure, OEM oil filter part number and drain plug torque. None appear in the owner’s manual pages used here.
