If octane 88 is used, what does the material imply?

• A. It meets the minimum octane requirement.
• B. It does not meet the minimum octane requirement.
• C. It is acceptable only in special models.
• D. It is recommended for cold weather.

Answer: (B)

Interpreting minimum octane requirements means the engine needs fuel at or above a specified octane level to run safely and smoothly. If octane 88 is used, it sits below the minimum rating the material expects. That minimum is set to prevent knocking and ensure proper combustion; using fuel below it can lead to knocking, reduced power, and potential engine stress. So the material implies the fuel does not meet the minimum octane requirement. The other options aren’t supported because the spec isn’t describing suitability for special models or cold-weather use, and it isn’t saying that 88 meets the minimum.
