Final answer:

Premium gasoline does not burn faster than regular gasoline; it actually burns in a more controlled manner due to its higher octane rating, making it suitable for engines with high compression, and helps prevent engine knocking or pinging.

Step-by-step explanation:

The statement that premium grade gasoline burns faster than regular gasoline is false. Premium gasoline has a high octane rating, which indicates its ability to resist knocking or pinging in a combustion engine.

Contrary to burning faster, a higher octane rating means that the fuel burns in a more controlled manner, making it suitable for high compression engines. Regular gasoline with a lower octane rating is more prone to premature combustion when used in such engines, which can lead to engine damage due to the uneven burning that causes knocking and pinging.
