Haval H4 requires 5w30 engine oil. The steps for changing the engine oil are as follows: 1. Lift the vehicle, remove the underguard, and place a container with a capacity of about 10 liters below the oil drain plug. 2. Unscrew the oil drain plug, use an air gun to blow for two minutes at the oil filler port, then tighten the oil drain plug after draining and wipe it with a tissue to check for leaks. 3. Reinstall the underguard and lower the vehicle, then use a funnel to add oil through the oil filler port. Taking the 2020 Haval H4 LeXiang Edition as an example, its body dimensions are: length 4410mm, width 1845mm, height 1695mm, with a wheelbase of 2660mm and a fuel tank capacity of 55 liters. The 2020 Haval H4 LeXiang Edition features a MacPherson independent front suspension and a double-wishbone independent rear suspension. It is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 150PS, maximum power of 110kW, and maximum torque of 210Nm.

I've been driving a Haval H4 for several years, and I always use 5W-30 synthetic oil when changing the engine oil, as recommended in the user manual. It adapts well to various temperatures—not too thick in summer nor too thin in winter—keeping the engine running smoothly. I change it every 5,000 kilometers and regularly check the oil level to avoid low oil-related issues. Synthetic oil offers higher durability, better protecting engine components and reducing friction noise and unusual sounds compared to mineral oil. When choosing oil, I look for products meeting API SN or higher standards to ensure authenticity and avoid counterfeit products. After changing the oil, the car's performance noticeably improves, and fuel consumption decreases slightly. In short, timely maintenance is key—don't skimp on small expenses only to face major repairs later.

As a tech-savvy car owner, my choice of engine oil for the Haval H4 is very clear: 5W-30 synthetic oil. The manual specifies this grade because of its excellent fluidity and protective performance, capable of handling both high and low temperatures as well as aggressive driving. I prefer the full synthetic version, which lasts longer under API standards, extending the replacement interval to around 8,000 kilometers. When changing the oil, pay attention to the dipstick markings to ensure the oil level is appropriate. If you drive frequently, the oil lifespan will shorten, so monitoring oil quality changes is crucial. Using high-quality synthetic oil can make power output smoother and reduce carbon buildup issues. Remember to record each replacement time for scientific maintenance.

I use the Haval H4 for daily driving, and for oil changes, I simply follow the manual's recommendation of 5W-30 synthetic oil. Make sure not to choose the wrong grade—it's simple and safe. Check the oil level every few thousand kilometers to confirm there are no leaks or degradation. Changing the oil on time helps prevent engine wear and noise; I usually change it every 5,000 kilometers. Maintaining standard procedures and avoiding unnecessary modifications or additives ensures the car runs smoothly. Regular maintenance not only saves money but also extends the vehicle's lifespan and enhances driving comfort. Choosing the correct oil grade is the crucial first step.
