What type of transmission oil does the Haval H6 use?

[IsabelleLynn]

The Haval H6 uses the original 75W-90 specification transmission oil. The transmission oil for the Haval H6 should be replaced at 6,000 kilometers, 52,000 kilometers, and 100,000 kilometers, and then every 50,000 kilometers or three years thereafter, whichever comes first. Different models have different replacement cycles. Below are the replacement cycles for transmission oil: Manual transmission: Manual transmission oil is generally recommended to be replaced every three years or approximately 100,000 kilometers. Automatic transmission: Automatic transmission oil is generally recommended to be replaced every two years or approximately 40,000 kilometers. Continuously variable transmission (CVT): CVT transmission oil is generally recommended to be replaced every two years or approximately 60,000 kilometers. The methods for replacing transmission oil are as follows: Unscrew the drain plug at the bottom of the transmission to drain the oil, then refill. Remove the transmission oil pan directly to drain and refill: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a circulation machine to replace automatic transmission oil: Dynamic oil replacement with an intelligent circulation machine can filter and clean sludge and impurities inside the automatic transmission.

When I drove the Haval H6 2nd-gen manual transmission before, I checked this. The maintenance manual specified GL-4 grade 75W-90 gear oil. However, there are significant differences between model years. For example, early manual transmission models could use this specification, but some owners of the 1.5T version reported smoother operation with 75W oil. Actually, the most reliable method is to check your vehicle's owner's manual - the parts specification table on the last page will definitely have the correct information. If you can't be bothered to check, just provide your VIN to the 4S parts department - their system will instantly tell you the exact specification, and you can ask about labor costs for the oil change while you're at it. Remember not to use automatic transmission fluid improperly - incorrect viscosity can damage synchronizers.

The transmission oil for the Haval H6 depends on the specific configuration. The older 6-speed manual transmission only requires GL-4 75W-90 mineral oil, the kind that costs about 50 yuan per liter. However, the third-generation automatic transmission uses a 7-speed wet dual-clutch system and requires a specialized low-viscosity DCTF oil, model HF-DCTF-1, which must be purchased from an authorized dealership. Once, a friend of mine tried to save money by using a generic transmission oil, and the gear shifts became as jerky as riding a horse. For automatic transmissions, it's recommended to change the oil every 60,000 kilometers, while manual transmissions can last up to around 80,000 kilometers.

Manual transmission owner speaking from experience: My old H6 manual gearbox has always used Fuchs GL-4 75W-90, and the shifting feel is exceptionally smooth. Remember never to use GL-5 oil! This oil has high sulfur content that can corrode the copper synchronizer rings - one transmission repair would cost you a decade's worth of oil. The required amount is approximately 2.2 liters, and a gravity fill is sufficient. For automatic transmission brothers, just go to the 4S dealership for the original factory oil - it's the most worry-free option, specifically Great Wall's own DCT specialized oil.

I just changed the transmission fluid for my H6 GT version two days ago. For automatic transmissions, you must use the manufacturer-certified DCT-specific oil, labeled as HF-DCTF-1 on the bottle. The mechanic said this oil has a viscosity of only 5.5cSt, while regular ATF oils are above 7, and mixing them could cause valve body malfunctions. It took about 4.5 liters, costing over 600 yuan including labor. Manual transmissions are simpler—any roadside shop can handle it with GL-4 75W-90, just two liters for around a hundred yuan. The key is not to mistake the transmission type.
