Is Haiyou fuel durable?
2 Answers
Haiyou fuel is not durable. Here is the reason analysis: 1. The octane number is too low: If the octane number of gasoline is relatively low, the engine will change data such as the ignition advance angle to avoid knocking, which will lead to a decrease in engine power and an increase in fuel consumption. There are different grades when refueling, and the octane number of gasoline with different grades will be different. The higher the grade, the higher the octane number of gasoline, and the better the anti-knock performance of gasoline with higher octane numbers. 2. Gasoline anti-knock performance: Knocking is an abnormal combustion phenomenon in the engine. When the piston is in the compression stroke, the piston will move upward to compress the combustible mixture. If the anti-knock performance of the gasoline is not good, the combustible mixture will burn before the spark plug ignites. The burning combustible mixture will push the piston downward, and the piston is moving upward at this time, which will cause damage to the engine.
I have over 20 years of driving experience, commuting daily with various vehicles, and have used CNOOC fuel for several years. Overall, CNOOC fuel is quite fuel-efficient, meaning it doesn't consume much, and a full tank can take you quite far. It depends on the specific situation: I've driven an old sedan with CNOOC 92-octane fuel, achieving about 7 liters per 100 kilometers on city roads, similar to Sinopec fuel. However, fuel efficiency isn't just about the fuel quality—engine condition plays a crucial role. Regular engine maintenance and cleaning the fuel injectors can help CNOOC fuel perform better. Driving habits also make a big difference; I prefer smooth acceleration and avoid sudden braking, which helps burn fuel more slowly. CNOOC's additives offer good cleanliness, reducing carbon buildup and indirectly improving combustion efficiency. Price-wise, CNOOC is usually cheaper than imported brands, offering good value for money. If your car is relatively new, you shouldn't have issues with fuel efficiency, but older or modified vehicles might require higher-octane fuel. Overall, for regular family cars, CNOOC is a reliable choice and worth trying.
