do cars really need higher octane
Broadly speaking there are three categories of octane requirement. In some vehicles itâs a-OK to run good olâ regular-grade petrol. However, in others manufacturers recommend premium for optimum performance. And finally in the third group high-octane gasoline is required for proper operation.
Is premium fuel worth the premium price? Can you hurt a high-octane car by running it on the cheaper stuff? There's no shortage of opinions on who is to blame for gas-price gouging. One thing that's certain is drivers tend to economize at the pump during extreme price rises-they buy cheaper, lower-octane gas.
