What type of engine oil should a Haval H2s use?
3 Answers
Haval H2s should use 5W30 engine oil. The type of engine oil a vehicle should use is best determined by the manufacturer's recommendation. The recommended engine oil specification can be found in the vehicle's user manual (maintenance manual), which provides detailed explanations. The Haval H2s is positioned as a compact SUV, with body dimensions of 4195mm in length, 1772mm in width, and 1638mm in height, a wheelbase of 2550mm, and a seating capacity of 5. The vehicle is exclusively front-wheel drive, featuring a MacPherson strut front suspension and a torsion beam rear suspension.
I've been driving a Haval H2 for almost three years, always using 5W-30 full synthetic oil for maintenance. The car's manual clearly states the recommendation for this grade, and I specifically checked the maintenance handbook to confirm. During the first service at the 4S shop, the mechanic also mentioned that the 1.5T engine is best suited for 5W-30 viscosity. Even in Northeast winters with temperatures as low as -20°C, it starts up just fine, and the engine remains stable during summer road trips. It's crucial to choose oil with ACEA C2 or C3 certification—the Great Wall original full synthetic is a good option. Remember to change it every 7,500 km, and don't skimp by using mineral oil; turbocharged engines need high-quality fuel. Last time, someone in the car owners' group mentioned using 10W-40, which caused their fuel consumption to skyrocket—totally not worth it.
Having worked on domestic cars for seven years, I know the Haval H2S's engine inside out. This 1.5T engine strictly requires 5W-30 full synthetic oil – turbocharged engines have higher oil specifications. A common customer mistake is randomly switching oil grades. Last time, someone used 5W-40, which noticeably slowed cold starts. The most accurate reference is the oil cap marking, which specifies the recommended 0W-30/5W-30 values. Focus on two key oil parameters: low-temperature fluidity ensures cold-start lubrication, while high-temperature viscosity protects the turbo. I recommend premium brands like Mobil 1, and always replace the filter simultaneously. Buying your own materials post-first-service can save 30%, but absolutely avoid no-name oil brands.
