What grade of gasoline should the Haval M6 use?
2 Answers
The Haval M6 should use 92-grade gasoline. Do not use high-grade gasoline for a long time, as it can alter the ignition timing. Prolonged use of high-grade gasoline is not only bad for the car but can also shorten the engine's lifespan. The gasoline grade is the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the grade, the stronger the anti-knock performance. Relevant information is as follows: 1. Gasoline of different grades has different octane ratings, and gasoline with a higher octane rating has better stability. 2. Gasoline with poor stability can easily cause engine knocking. Knocking occurs during the engine's compression stroke. During the compression stroke, the piston moves upward to compress the combustible mixture, causing the temperature and pressure of the mixture to rise. 3. If the gasoline's stability is poor, the combustible mixture may ignite prematurely. The burning mixture will push the piston downward while it is still moving upward, which can affect the engine's power output.
I've been driving a Haval M6 for several years, and my friend asked the same question when he first bought the car. According to the official manual, it's recommended to use 92-octane gasoline, which is the most common grade under the Chinese standard. The octane rating matches the engine's compression ratio, making it both economical and worry-free. There's no need to use 95-octane or higher—it's not worth the extra cost, and the performance improvement is minimal, unless you frequently drive on highways or mountainous roads where the engine is under heavy load to prevent knocking. Using lower grades like 90-octane or below is risky, as it may cause knocking sounds, reduced power, or even long-term piston damage. When I first got the car, I compared 92 and 95-octane and found little difference in fuel consumption, so I stick with 92. Also, pay attention to fuel quality—choose reputable gas stations and avoid cheap, small ones. Off-brand fuel often contains impurities that can clog injectors and harm engine longevity. It doesn't hurt to check the fuel system during regular maintenance. In short, 92-octane is the golden choice—it saves money and protects your car.
