Should the Kia K3 use 5W20 or 5W30?

The 1.5-liter naturally aspirated model of the Kia K3 can use 5W20 engine oil, while the 1.4-liter turbocharged model requires 5W30 engine oil. Additional information is as follows: 1. The Kia K3 is a compact car under the Kia brand, with a wheelbase of 2700mm, and its length, width, and height are 4660mm, 1780mm, and 1450mm respectively. 2. The 1.4-liter turbocharged engine of the Kia K3 delivers 130 horsepower and a maximum torque of 211 Nm. This engine is equipped with direct injection technology and uses an aluminum alloy cylinder head and block. It is paired with a 7-speed dual-clutch transmission. The 1.5-liter naturally aspirated engine produces 115 horsepower and a maximum torque of 143.9 Nm. This engine features multi-point fuel injection technology and also uses an aluminum alloy cylinder head and block. It is matched with a CVT transmission. 3. The front suspension of the Kia K3 uses a MacPherson independent suspension, while the rear suspension employs a torsion beam non-independent suspension. The use of a torsion beam rear suspension helps to maximize rear passenger space and trunk capacity.
For the oil selection of the Kia K3, my suggestion is to first check the owner's manual, as it will clearly specify the most suitable viscosity. Generally speaking, for newer K3 models, such as those from 2020 onwards, the manufacturer recommends using 5W20 because it is thinner, flows better during cold starts, and can improve fuel efficiency while reducing engine wear. However, for older K3 models or if driving in high-temperature regions, 5W30 might be more suitable as it has a moderate thickness, providing more stable protection during long-distance driving or in hot weather. My experience is that you should not arbitrarily change oil types, as this may affect engine lifespan; regularly check the oil level, and if you frequently drive in city traffic or take frequent short trips, sticking to the recommended grade can reduce wear risks. Saving a bit of money to buy better oil is more cost-effective in the long run. Remember, the maintenance manual is your best friend! Don’t overlook small details to ensure your engine runs smoothly.
