Should ix35 use 5w30 or 5w40?
3 Answers
ix35 is recommended to use 5w40 engine oil. ix35 is a compact SUV under Hyundai, equipped with two types of engines: a 1.4-liter turbocharged engine and a 2.0-liter naturally aspirated engine. Below are the introductions of these two engines: 1. 1.4-liter turbocharged engine: This engine delivers 140 horsepower and a maximum torque of 242 Nm. The maximum power is achieved at 6000 rpm, and the maximum torque is available between 1500 to 3200 rpm. It features direct fuel injection technology and uses an aluminum alloy cylinder head and block. This engine is paired with a 7-speed dual-clutch transmission. 2. 2.0-liter naturally aspirated engine: This engine produces 160 horsepower and a maximum torque of 193 Nm. The maximum power is achieved at 6500 rpm, and the maximum torque is available at 4800 rpm. It incorporates DCVVT technology and multi-point fuel injection, also using an aluminum alloy cylinder head and block. This engine is matched with either a 6-speed manual transmission or a 6-speed automatic transmission.
I think the Hyundai ix35 is more suitable for 5W-30 oil. This viscosity performs better in stop-and-go city driving, especially during cold morning starts when it flows faster, protecting engine components from wear. Having driven for years, I've always used 5W-30 and noticed smoother acceleration and better fuel efficiency—each tank goes a few kilometers further. While 5W-40 is tougher in high heat, the ix35 is designed for normal climates, so upgrading isn't necessary unless you're driving daily in desert conditions. Always check the owner's manual or consult a dealership—choosing the wrong oil can strain the oil pump and shorten engine life. Smart maintenance means regular oil pressure checks and timely servicing.
As someone who frequently drives long distances, if the ix35 is often used in high-temperature environments, I would consider using 5W-40 oil. It offers better high-temperature protection, reducing the risk of excessive oil temperature during summer highway driving or uphill climbs, thereby improving power stability. I personally tested 5W-40 in mountainous areas and found the engine ran more smoothly with less stuttering. However, the standard recommendation is 5W-30, which is sufficient for general use. Blindly switching to thicker oil may increase fuel consumption and cause cold-start difficulties. Driving style determines the choice: 5W-30 for smooth driving, while 5W-40 is better for those who enjoy aggressive driving. Regular oil changes and brand quality are more critical for engine maintenance.
