Haval H2 is suitable for 10W40 engine oil. The functions of engine oil include lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. Taking the 2018 Haval H2 as an example, it is a compact SUV with body dimensions of 4365mm in length, 1814mm in width, and 1710mm in height, a wheelbase of 2560mm, a fuel tank capacity of 50L, and a curb weight of 1450kg. The 2018 Haval H2 features a MacPherson independent front suspension and a multi-link independent rear suspension. It is powered by a 1.5T turbocharged engine with a maximum horsepower of 150PS, a maximum torque of 210Nm, and a maximum power output of 110kW, paired with a 6-speed manual transmission.

I've got some insights on choosing engine oil for the Haval H2, as my own car has the same 1.5T engine. The manual recommends using 5W-30 viscosity, with a focus on certification standards—it must be full synthetic oil with API SN or SP grade, given the high precision of turbocharged engines. Personally, I use Mobil 1 or Shell Helix Ultra, which are suitable for all seasons, fuel-efficient, and provide smooth cold starts in winter. Never skimp on quality by buying off-brand mineral oils, as they lack sufficient high-temperature protection and can easily cause cylinder scoring. If you frequently drive on highways or live in cold northern regions, you might consider a low-viscosity 0W-30 variant. For each oil change during maintenance, don’t exceed 8,000 kilometers, and make sure to check if the oil filter is compatible—cheap filters from roadside shops can seriously harm your engine.

My neighbor has been repairing cars for ten years, and he says the turbo engine of the Haval H2 is particularly demanding on oil quality. You should choose a full synthetic oil with A3/B4 or C3 certification, like Great Wall's Jinjixing J700, which has a specially formulated recipe tailored for domestic brands. Using 5W-40 in summer is more reliable, as it offers better high-temperature shear resistance, preventing oil film rupture and piston ring damage. If you want to save money and use semi-synthetic oil, make sure it's at least SL-grade or above, and change the oil at 5,000 km. For older cars with noticeable oil consumption, try a higher viscosity 10W-40 as a temporary solution, but don't use it long-term, or fuel consumption will skyrocket. When changing the oil, remember to have the mechanic completely drain the old oil—mixing residue with new oil is like not changing it at all.

Choosing the right engine oil depends on viscosity grade and performance level. The Haval H2 owner's manual recommends 5W-30 viscosity, with SP-grade full synthetic being optimal for balancing cold-start performance and high-temperature protection. Here are three well-tested recommendations: Shell Penzzoil P9 Pro excels in cleaning performance, Castrol Edge responds quickly to power demands, and KunLun KR9 offers great value. Don't blindly trust imported oils—focus on whether the container bears the GF-6A certification mark. Mineral oils are absolutely unsuitable as turbocharger temperatures are too high and may cause sludge formation. In humid southern regions, consider changing oil every six months, while northern cold climate areas should prioritize 0W grades. Use exactly 4 liters per oil change—overfilling increases crankshaft resistance.
