Can a Volkswagen 1.4T Engine Use 92 Octane Gasoline?

[StBethany]

Volkswagen 1.4T engine can use 92 octane gasoline for short-term use. The difference between 95 and 92 octane: Higher octane rating means better anti-knock performance. 95 octane gasoline has anti-knock performance equivalent to a standard fuel containing 95% isooctane and 5% n-heptane, while 92 octane gasoline is equivalent to a standard fuel containing 92% isooctane and 8% n-heptane. Engine model: The Volkswagen 1.4T turbocharged engine is the EA211 model with a compression ratio of 10.5:1. Therefore, it is better to use the officially recommended 95 octane gasoline with relatively higher anti-knock performance. If the gas station happens to be out of 95 octane, the owner can add an appropriate amount of 92 octane gasoline and switch back to 95 octane at the next refueling.
