Potential Consequences
Higher octane gasoline also helps prevent a phenomenon known as “engine knock,” which results from the premature ignition of the fuel-air mixture in the engine’s cylinders. By filling up your luxury car with regular gasoline, the lower octane rating may cause the engine to knock, reducing its efficiency and performance.
While occasional use of regular gasoline might not immediately lead to catastrophic failures, a consistent pattern of using lower octane fuel can contribute to things such as:
- carbon buildup
- reduced fuel efficiency
- increased wear and tear on vital engine components
