What Type of Engine Oil Should an Arrizo 5 Use?
3 Answers
Arrizo 5 originally uses SM grade 10W-40 engine oil. Below is extended information regarding engine oil selection for the Arrizo 5: 1. As an economical model, semi-synthetic engine oil is the preferred choice. The Arrizo 5's engine does not have specific brand requirements for engine oil, as long as it meets the specifications. If the local temperature is lower, switch to 5W-40 grade engine oil. 2. Fully synthetic engine oil can also be used, as it offers better performance, resulting in lower engine noise and wear, though the oil change interval will be shorter. 3. It's important to note that the choice between fully synthetic and semi-synthetic engine oil applies to naturally aspirated engines. For turbocharged engine versions, only fully synthetic engine oil should be used.
I also drive an Arrizo 5, and the key point during maintenance is to check the oil viscosity rating. The manual clearly states that 5W-30 or 5W-40 full synthetic oil is most suitable, such as API SN grade or above. I often use Shell Helix Ultra 5W-30, and the engine idle is noticeably quieter, with much smoother starts. During summer when running the AC on the highway, I tried switching to 5W-40, and the high-RPM sound became more solid. Never cheap out and use mineral oil—my neighbor used some no-name mineral oil, and within six months, there were strange noises during cold starts. When changing the oil yourself, pay attention to the dipstick marks. Last time, an apprentice overfilled it, causing a spike in fuel consumption. Remember to check the oil quality every 5K km; if you’re stuck in city traffic often, you can change it earlier at 7K km. Buy from authorized stores of big brands—I once bought fake Mobil oil online, and it caused me a lot of trouble.
According to Chery's official maintenance manual, the Arrizo 5 recommends using fully synthetic engine oil with a viscosity of 5W-30 or 5W-40. I've personally tried three different brands and found that Castrol Edge 5W-30 works best for daily commuting, offering quick engine response and good fuel economy. It starts smoothly even in sub-zero winter temperatures below -10°C, but if you frequently drive on highways, switching to 5W-40 is advisable. At repair shops, I've seen some owners mistakenly use 10W-40 oil, which triggered cold-start engine warnings. The oil grade should be at least SN, and SP grade is better for newer cars. Don't exceed the 8,000 km maintenance interval – replace it earlier if you often encounter stop-and-go traffic. Also, remember that OEM oil filters provide the best compatibility; avoid cheap off-brand alternatives. When selecting oil, check the production date – oil stored for over two years loses its effectiveness.
