What oil should be used for Great Wall 1.5T engine?
3 Answers
You can use 5W-30 full synthetic oil, such as the Shell Helix Ultra series, which is suitable for most luxury cars, turbocharged models and high-performance sports cars. The following is the relevant introduction of Great Wall: 1. Introduction: Great Wall Motor is a Chinese automobile brand founded in 1984, headquartered in Baoding City, Hebei Province, mainly producing SUVs, cars, pickups and new energy vehicles. Great Wall Motor is the first private automobile enterprise listed on Hong Kong H-shares in China, the largest professional SUV and pickup factory in China, and a multinational company. 2. Brands: Great Wall Motor has five vehicle brands: Haval, WEY, Ora, Tank and Great Wall Pickup.
I've been driving my Great Wall H6 SUV with a 1.5T engine for several years, consistently using 5W-30 full synthetic oil. I've changed it myself a few times and found this viscosity particularly suitable for turbocharged engines—the engine runs smoothly, acceleration is more responsive, and fuel consumption in city driving isn't high, saving about half a liter per 100 kilometers. I usually change the oil every 8,000 kilometers along with a new filter, preferring reputable brands like Mobil or Shell for their strong compatibility and excellent high-temperature resistance. In northern winters when temperatures drop, 0W-30 can also work, but 5W-30 is sufficient for most regions. The manual recommends this viscosity, and I once made the mistake of using low-quality oil, which caused noticeable engine vibration—switching back promptly resolved the issue. Overall, choosing the right oil extends engine life and makes driving more worry-free. Remember to check oil levels regularly; don't wait for the warning light.
I've researched the engine oil selection for Great Wall's 1.5T engine. As a small-displacement turbocharged engine, it has higher requirements for oil viscosity. Generally, 5W-30 full synthetic oil is recommended because this viscosity offers good fluidity during cold starts, enabling rapid lubrication of turbo components to reduce wear while maintaining stable viscosity at high temperatures. The API standard should preferably be SP grade to meet modern engines' low-ash requirements. I frequently help friends choose oil - for Great Wall's V models using this viscosity, the acceleration response becomes smoother. Avoid overly thin 0W-20 oil as it may increase oil pressure fluctuations. For brands, either Castrol or Great Wall's own brand are suitable, with an optimal oil change interval of 8,000-10,000 km. Engine oil selection directly impacts performance and fuel efficiency - neglecting it can lead to additional maintenance costs.
