What Grade of Gasoline Should a Haval Car Use?
2 Answers
Haval cars should use 92-octane or higher gasoline. Do not overfill the tank: Overfilling the gasoline tank can easily block the vent hole. Once the vent hole is blocked, the air pressure inside the tank will drop below normal, leading to poor fuel supply or even a complete lack of fuel. Overfilling also increases the vehicle's weight, thereby increasing fuel consumption. Additionally, gasoline can deteriorate, posing a safety hazard. Avoid waiting for the low fuel warning: While driving, always monitor the fuel gauge. When the gauge shows only a quarter of the tank remaining, it's time to refuel. If the tank is left empty for too long, the temperature difference between the inside and outside can cause moisture to form inside the tank. This moisture can corrode the tank, degrade fuel quality, and increase the engine's workload.
I've been driving a Haval for several years, and every time I go to the gas station, I choose 92-octane gasoline without hesitation—it's the most cost-effective option. According to the user manual, most Haval models like the H6 or Big Dog recommend 92-octane or higher, as it matches the engine's anti-knock performance and avoids premature damage. Always check the label inside the fuel filler cap, where the official recommendation is printed. I don’t think it’s necessary to use 95-octane gasoline. While some claim it slightly boosts horsepower, it’s significantly more expensive, and Haval’s engine design is optimized for the economy of lower-octane fuel. Long-term use of the wrong octane rating may lead to carbon buildup or engine knocking, which isn’t worth the trade-off. Remember to choose reputable gas stations—consistent fuel quality ensures smoother driving. My own experience has shown that sticking with 92-octane saves a lot of money, extends maintenance intervals, and rarely causes major issues.
