Can the T-Roc use 92 octane gasoline?
1 Answers
T-Roc cannot use 92 octane gasoline; it requires at least 95 octane gasoline. Here are the relevant details: 1. Most turbocharged engines require 95 octane gasoline. Gasolines with different octane ratings have varying levels of octane numbers; higher-octane gasoline has higher octane numbers, and higher-octane gasoline also offers better stability. 2. If 92 octane gasoline is used when 95 octane is required, it can cause engine knocking. Knocking is an abnormal combustion phenomenon in the engine, which occurs during the compression stroke. During the compression stroke, both the intake and exhaust valves are closed, and the piston moves upward to compress the air-fuel mixture. The temperature and pressure of the compressed mixture increase. If the gasoline's stability is poor, the mixture may ignite prematurely. The ignited mixture pushes the piston downward while it is still moving upward, which can negatively affect the engine's power output and fuel efficiency.
