What is the best motor oil for Kia Optima? This question was posed to me by a customer who wanted to know what type of oil he should buy for his car. I thought it would be best if I answered this question and shared my findings with other people on the internet so they could benefit from it as well.
In this blog post, we will discuss which types of oils are best for Kia Optima (or Kia K5 since 2019) and why some oils might not work as well as others. We’ll also talk about how using synthetic engine oil can help you save money in the long run!

2019 2020 2021 2022 Kia K5 Engine Oil Capacity
The 2022 Kia K5 is classified as a family sedan, but its attractive design and 290-hp engine option suggest something sexier. Sure, the previously known as the Kia Optima isn’t about to take on its perennially excellent adversary, the Honda Accord, but the K5’s wide range of standard features and reasonable pricing make it a compelling value alternative. Every variant comes standard with active safety technology and infotainment systems, with the sedan’s pleasant interior complemented by a spacious rear seat.
The souped-up engine is standard on the K5 GT, and tire-spinning behaviors will either attract or repel customers. The basic powertrain is rather modest, and it’s the only way to get an all-wheel drive. Despite a high driver’s seat that suffers from poor isolation due to the largest possible wheel-and-tire combination, as well as an uncomfortable driving position overall, the 2022 K5 sedan is an incredible vehicle—whether purchased for a family or not.

Recommended Engine Oil For Kia Optima (K5)
The viscosity of engine oil has an influence on fuel efficiency and cold-weather operation (engine start and engine oil flowability). Engine oils with a lower viscosity might offer improved fuel economy and cold-weather performance, but higher-viscosity engine oils are required for optimal lubrication in hot weather.
Using oils of any viscosity other than those specified might cause engine damage. Consider the range of temperature your vehicle will be operated in before the next oil change while selecting an oil. Continue to pick the required oil viscosity from the chart.

An authorized Kia dealer should replace the engine oil and filter.
The engine oil and filter should be changed at the times suggested in the maintenance program. If the car is driven in harsh weather, more frequent oil and filter replacements are advised.
Engine oil, especially if it has been utilized for a lengthy time, can irritate or cause cancer in the skin if it is continuously exposed. Engine oil contains chemicals that have been demonstrated to induce cancer in laboratory animals.
As soon as possible, wash your hands thoroughly with soap and warm water after handling old oil to prevent irritation or disease of the skin. Children should not be allowed access to old engine oil.
How Much Oil Does a Kia Optima Take?
The 2022 2.5L Turbo Kia K5 (Kia Optima) takes 6.1 quarts (5.8 liters) of 0W-30 oil.
TOP TIER Detergent Gasoline, which includes detergent additives to help prevent deposit formation in the engine, is a good example of high-quality gasoline.
Clean gasoline will help the engine run more smoothly and improve the emission control system effectiveness.
If TOP TIER Detergent Gasoline isn’t accessible, one bottle of additive should be put in the tank every 7,500 miles (12,000 km) or at each engine oil change. Additives can be purchased from your authorized Kia dealer and given instructions on how to use them. Do not combine different additives.
