Should the Volkswagen Polo use 92 or 95 octane gasoline?
2 Answers
The Volkswagen Polo uses 92 octane gasoline. Additional information: 1. The difference between 95 and 92 octane gasoline lies in the isooctane value. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane, resulting in different anti-knock properties. Therefore, it is generally recommended to follow the manufacturer's suggested gasoline type. 2. In special circumstances where fuel is unavailable, mixing the two types of gasoline usually does not cause major issues, but prolonged use should be avoided as it can lead to knocking, power shortages, etc. Similarly, a car that normally uses 95 octane gasoline can occasionally use 92 octane without significant problems, but long-term use will increase the frequency of knocking and accelerate engine wear.
I've been driving a Volkswagen Polo for almost five years and always insisted on using 95-octane gasoline. The manual recommends 95-octane, and I initially tried 92-octane but noticed poorer power response—the throttle felt sluggish, and I occasionally heard slight knocking sounds. Later, a mechanic at the repair shop explained that the Polo's engine has a high compression ratio, making 95-octane more suitable due to its higher octane rating, which reduces engine wear and improves combustion efficiency. In the long run, even though 95-octane is slightly more expensive, it saves on repair costs. For daily commuting, using 92-octane might save money short-term, but deteriorating engine condition would lead to costlier repairs. Remember to check the spark plugs every six months—it's crucial for maintaining performance. My experience is that sticking to 95-octane as recommended keeps the car running smoothly and ensures stable mileage.
