What type of engine oil does the Haval F7 use?
4 Answers
Haval F7 uses a fully synthetic engine oil with a viscosity of 40. Engine oil is often referred to as the lifeblood of the engine, playing a crucial role in its operation. Without engine oil, the engine cannot function properly. Inside the engine, oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. During normal engine operation, the oil forms a thin film on the surfaces of various engine components, preventing direct contact and friction between them. The Haval F7 is the second model in Haval's F series, a compact SUV with dimensions of 4620 mm in length, 1846 mm in width, 1690 mm in height, and a wheelbase of 2725 mm.
I've been driving a Haval F7 for three years and have changed the engine oil several times. The 4S店师傅 told me that 5W-30 full synthetic oil is most suitable for this car, and it's also written in the manual. For summer long-distance driving or as the car ages, using 5W-40 with higher viscosity is more stable. Nowadays, domestic full synthetic oils are completely sufficient, such as Mobil 1 or Great Wall Jinjixing, which work very well. Never be tempted to buy cheap oil from small workshops. Last week, I changed the oil myself and found that 5W-30 starts much faster in cold winter mornings. Remember to replace the oil filter with every oil change, otherwise, the new oil mixing with old impurities can be very damaging to the engine. This car basically needs an oil change every 7,000 to 8,000 kilometers, and you should pay attention if the idle noise increases.
I've serviced dozens of Haval F7s, and I recommend using 5W-30 full synthetic oil for both the 1.5T and 2.0T models. For new cars, it's best to follow the manual. In areas with temperatures below -20°C, 5W-30 ensures faster starts. For older cars with over 100,000 kilometers, you might try 5W-40 for better protection, but make sure the oil grade is SN or higher. Some owners complain about high fuel consumption, only to find out they were using old 40-viscosity oil—switching back to 30-viscosity immediately improves fuel efficiency. I recommend changing the oil filter every time. Once, I saw oil that turned as black as ink after just 3,000 kilometers because the filter wasn't replaced. Northern owners should especially remember to switch to winter oil before December—don't wait until it freezes.
Last year, I thoroughly researched when changing the oil for my Haval F7. After checking the manual and car owner groups, the conclusion was that using 5W-30 full synthetic is the safest bet. When getting maintenance at the shop, I always keep an eye on the mechanic to avoid wrong specifications—once they almost added 10W-40. During the summer heat, I switched to 5W-40 once, but didn’t notice much difference in performance. I’ve bought Shell Helix Ultra from the official website and Great Wall Dry Series, and now I realize domestic oils offer great value for money. When changing the oil, the oil pan bolt should be tightened gently—my neighbor once stripped the threads, causing a leak. Regularly checking the dipstick is crucial, and I keep the maintenance schedule in my phone reminders.
