|
| 48. | Octane ratings measure a gasoline's ability to cut down on engine " knocking, " which results when fuel burns unevenly.
|
| 49. | It is also harmful to modern engines due to its low octane rating, high heat of combustion and lack of additives.
|
| 50. | If they have received consumer complaints about poor performance, they send the gas to a lab to test its octane rating.
