Which type of engine oil is suitable for the Haval F7?
3 Answers
The Haval F7 is equipped with two types of engines, namely the GW4B15 and GW4C20NT, which require the use of fully synthetic engine oil. The following recommendations apply to the selection of engine oil: 1. If you choose engine oil that meets the ACEA (European Automobile Manufacturers' Association) standards, the recommendation is: If the temperature in your region is above -30°C, use A3/B4 5W-40 oil. If the temperature in your region is lower, use A3/B4 0W-40 oil. 2. If you choose engine oil that meets the ACEA (European Automobile Manufacturers' Association) standards, the recommendation is: If the temperature in your region is above -30°C, use C1/C2 5W-30 fully synthetic oil. If the temperature in your region is lower, use C1/C2 0W-30 fully synthetic oil. Like gasoline, a higher grade does not necessarily mean better performance. There is no 'best' engine oil, only the most suitable one.
When driving the Haval F7, the question I get asked most often is about engine oil selection, as it directly impacts engine longevity. Generally, I recommend using full synthetic oil with a viscosity of either 5W-30 or 0W-20, depending on local climate and driving habits. The Haval manual provides detailed guidance—for example, 0W-20 ensures smoother cold starts in freezing regions, while 5W-30 prevents overheating in summer heat. Personally, I’ve used Shell and Mobil full synthetic oils, and noticed the engine runs quieter while saving about 10% on fuel. Stick to oil changes every 5,000–7,500 km—delaying risks sludge buildup and costly part damage. And never skip replacing the oil filter; this cheap little part (just tens of RMB) offers huge protection.
When it comes to the Haval F7's engine oil, I recommend prioritizing semi-synthetic or full-synthetic types, with viscosity suitable for the environment. For example, choose 0W-20 for northern winters, while 5W-30 is sufficient for daily use in the south. This reduces engine wear and extends service life. I've used Great Wall's original equipment oil, which offers good value for money—around 200 RMB per maintenance session. Remember to regularly check the oil dipstick to ensure proper oil levels and avoid cylinder scoring due to oil shortage. The replacement interval should ideally be every six months or 7,500 kilometers—don’t wait until the engine makes strange noises. Oil quality directly affects power output and fuel consumption; good oil ensures smoother starts.
