Should the Golf use 92 or 95 octane gasoline?
1 Answers
The Golf 1.2T, 1.4T, and 2.0T turbocharged engines are recommended to use 95 octane gasoline, while the 1.6L naturally aspirated engine is recommended to use 92 octane gasoline. Relevant information about gasoline octane ratings is as follows: 1. The gasoline octane rating refers to the ratio of the actual gasoline's anti-knock performance to that of standard gasoline. The higher the octane rating, the stronger the anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. Higher octane ratings are not necessarily better; the appropriate gasoline octane rating should be selected based on the engine's compression ratio. 2. There is essentially no difference in quality between 92 and 95 octane gasoline, as neither contains fuel impurities. The difference in octane ratings is due to the varying proportions of their internal components, specifically the differing content of n-heptane and isooctane.
