Standard Gasoline Maintenance Intervals

see Owner’s Manual The Optima is discontinued and we have not independently confirmed every figure below against a Optima-specific owner's manual. What follows is Kia's documented standard gasoline-engine service structure — the same interval pattern confirmed across Kia's current gas-powered lineup — applied by analogy. Spark plugs and the first coolant change vary the most by engine and generation, so those rows are explicitly flagged. Bring your VIN or owner's manual on your next visit and we’ll confirm your exact schedule at no charge.

About the Kia Optima

Final US Model Year: 2020
Kia Optima Discontinued Legacy Model
Kia sold the Optima in the US through the 2020 model year; starting with model year 2021, Kia renamed this nameplate the K5 in the US market rather than replacing it with an unrelated model. Every Optima on the road — any model year — still qualifies for full factory-scheduled service at Dean McCrary Kia.
