Frequently Asked Questions

6 common questions answered

Is the oil filter replaced every time a 2018 Kia Optima has its oil changed?Yes, the manufacturer's published schedule for the 2018 Kia Optima states that the oil filter should be replaced every 3,000 miles.

Replacing the filter with the oil renews the component that captures debris. A loaded filter can open its bypass valve, allowing unfiltered oil to circulate. Your vehicle's service history helps confirm what is due.

  • Filter replacement alongside the oil
  • Filter matched to the fitted engine
  • Leak check after the engine runs
What is included in an oil filter replacement on a 2018 Kia Optima?The service includes an engine-matched filter, a new drain plug gasket or washer where used, and a leak check after the engine runs.

The filter is selected for the engine actually fitted to the sedan. The sealing component is renewed where the engine uses one, and the filter seal is checked after operation. You can schedule service online.

  • Filter matched to engine specification
  • New gasket or washer where applicable
  • Post-service filter seal inspection
What happens if the oil filter on a 2018 Kia Optima is not replaced?A loaded filter can open its bypass valve, allowing oil to circulate without filtration.

The engine still receives oil, but it may no longer receive filtered oil. Debris carried by the oil remains the reason the filter is replaced with the oil rather than stretched across two changes. An inspection and service history help determine what the vehicle needs.

  • Debris is held by the filter
  • Bypass operation can send unfiltered oil through
  • Oil service does not renew an old filter automatically
Does a 2018 Kia Optima need a specific oil filter?Yes, the filter must be matched to the 1.6 to 2.4-liter inline-four engine fitted to the vehicle, because filters are not interchangeable across engines.

The 2018 Kia Optima engine range spans 1,591 to 2,359 cc. Herb Chambers Kia of Burlington can match the filter to the engine actually fitted without relying on a generic fit. The service also includes a seal leak check after the engine runs.

  • 1.6 to 2.4-liter displacement range
  • Inline-four engine layout
  • Engine-matched filter selection
Can the oil be changed on a 2018 Kia Optima without changing the filter?The oil can be changed separately, but the manufacturer's schedule calls for replacing the oil filter every 3,000 miles.

Using an old filter leaves the component that holds debris in service after the oil is renewed. Once loaded, its bypass valve opens and unfiltered oil circulates. The manufacturer's schedule and the vehicle's service history determine the appropriate maintenance.

  • Filter replacement is paired with scheduled oil service
  • Loaded filters can bypass filtration
  • Service history helps establish what is due
