Question

using an octane rated higher than your vehicle______. will burn your cylinder heads does not increase power gives it more power is safer for the environment

Explanation:

• "will burn your cylinder heads": Higher octane fuel than required doesn't cause cylinder head burning. Engine design determines safe octane, and excess octane doesn't lead to this.
• "does not increase power": A vehicle's engine is tuned for a specific octane. Using higher octane than needed doesn't add power as the engine isn't designed to utilize the extra anti - knock properties of higher octane for more power.
• "gives it more power": The engine's power output is determined by its design (compression ratio, etc.). Higher octane than required doesn't provide more power since the engine can't take advantage of the higher octane's characteristics to generate more power.
• "is safer for the environment": Octane rating relates to anti - knock properties, not environmental safety. Using higher octane than needed doesn't inherently make it safer for the environment.

Answer:

B. does not increase power
