Haval H6 upgraded version uses semi-synthetic engine oil with SL grade and 10W-40 viscosity. Introduction to engine oil: Engine oil, also known as engine lubricant, serves multiple functions including lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, as well as shock absorption. Precautions for using engine oil: Engine oil selection should be based on the requirements of the engine. Choose engine oil that matches the engine specifications. Multi-grade oil is recommended as it offers advantages such as fuel economy, extended service life, and high efficiency, providing better protection for the engine. The oil level should be slightly below the mark on the dipstick; avoid overfilling.

I've been driving my Haval H6 upgraded version for over two years, and I'm used to using fully synthetic 5W-30 engine oil, which is recommended in the manual. It protects the engine from stalling and extends its service life. I mostly drive in the city, where the oil temperature doesn't get too high, so 5W-30's moderate viscosity is perfect, and the oil change interval is longer—usually every six months or 7,500 kilometers. Remember to check your car's model year; if the engine is noticeably turbocharged, don't skimp by using semi-synthetic oil. Before changing the oil, always check the oil level and ensure the filter is clean—it saves money and gives peace of mind. This viscosity ensures quick starts in winter and resists evaporation in summer heat. Regular maintenance can save you from costly repairs, so I always go to an authorized service center where they understand Haval's specific requirements.

As a city commuter, I prefer engine oil with stable performance. I use 5W-40 full synthetic for my H6 upgrade. With frequent traffic jams in the city, a thicker oil film reduces engine noise and provides quicker acceleration response. I manually checked the owner's manual, and most turbo models across different years support this specification. Don't skimp by using mineral oil—it wears out faster and requires more frequent changes. Spending a bit more on full synthetic makes the car run smoother. Changing it every 8,000 kilometers is the most hassle-free. Also, remember not to overfill the oil—check the dipstick markings to avoid blue smoke from burning. Regular engine maintenance can extend its life by several years.

Driving the family-oriented Haval H6, saving money is the top priority. I use semi-synthetic 5W-30 oil, which has the right viscosity, and change it every 5,000 kilometers. The manual only requires API SN grade, and semi-synthetic oil saves one-third of the cost compared to full synthetic while delivering adequate performance. When taking the kids out, the engine runs quietly with moderate oil temperature. Always choose reputable brands to avoid counterfeit products damaging the car. The oil change interval is shorter, but it’s cost-effective overall. Replace the oil filter simultaneously to prevent impurity buildup. Cold starts are easy in winter, and don’t neglect cooling in summer. Economical driving can extend the H6’s service life by several years.
