Haima's original engine oil model is 5w40. Engine oil, also known as engine lubricant, serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, as well as shock absorption. Often referred to as the 'blood' of a car, engine oil consists of base oil and additives. Taking the 2017 Haima M6 as an example, it is a mid-size sedan with body dimensions of 4700mm in length, 1802mm in width, and 1478mm in height, featuring a wheelbase of 2730mm, a minimum ground clearance of 190mm, and a curb weight of 1435kg. This model is equipped with a 1.5T turbocharged engine delivering a maximum torque of 223Nm and a maximum power of 120kW, paired with a 6-speed manual transmission.

I've been driving my Haima car for many years. The original engine oil specifications are usually 5W-30 or 5W-40, depending on what the vehicle manual states. My car uses 5W-30, which has moderate viscosity and is suitable for both winter and summer, ensuring quick cold starts and stable high-temperature lubrication. I get it changed at the 4S shop myself, and the engine runs quietly and smoothly afterward. Changing it every 5,000 kilometers is the most worry-free approach. Not following the manufacturer's recommendations can accelerate wear, increase sludge buildup, and double repair costs. I've tried other brands, but the original oil fits best, saving money and preserving engine life. Many car owners overlook this and only change the oil when the warning light comes on, only to regret it later.

As a mechanic who frequently services Haima vehicles, I'd like to remind you that the primary factory-recommended oil specification is 5W-30. SAE 5W-30 has low viscosity with excellent cold-weather fluidity, providing optimal engine protection against wear. We recommend genuine oil because it's specifically formulated for Haima's engine design, meeting API SN or SP full-synthetic standards for extended heat resistance. Always check oil levels during changes - never let it dip below the dipstick minimum. In high-temperature regions, you may upgrade to 5W-40. Oil quality significantly impacts performance; using aged or mixing with inferior oils may cause abnormal engine noise. My professional advice: adhere to scheduled and strictly follow the manual's recommended specifications to maximize your vehicle's durability.

My newly purchased Haima car's manual clearly states that the factory-recommended oil is 5W-30. After using it, the acceleration is smooth, fuel economy is good, and it's convenient and cheap to buy online. Changing it yourself isn't difficult, just find a repair shop. Choosing the right viscosity is important; don't make a mistake when temperature differences are large, otherwise the engine will make noise. Haima car owners should pay more attention to this small matter. Oil is simple and saves the hassle of car repairs.

I've been working at Kaihai for several years. The manufacturer recommends 5W-30 oil, which is practical and durable. I use it to keep the engine running smoothly and reduce vibration. Female car owners should pay attention to these details to ensure safe driving. Check the manual to confirm the model, don't randomly switch brands, and trust the reliable service of 4S shops. The right viscosity extends engine life, reduces fuel consumption, and makes minor worry-free. When temperature differences are large, upgrading to 5W-40 is better. Regular oil changes maintain engine health.

I prioritize eco-friendly driving. Haima's original 5W-30 is mostly fully synthetic oil, which is less polluting and recyclable, matching the engine for efficient operation. Using low-emission grade oil reduces carbon footprint, and synthetic types last longer with extended oil change intervals to minimize waste. Confirm the manual's specifications for climate adaptation—use higher viscosity in hot weather to protect resources while maintaining performance. Choosing original factory-matched oil results in lower engine noise and simpler , contributing to ecology.
