Save money by using regular gas, says consumer advice website

Consumers can save themselves money by opting for non-premium fuel, a leading US consumer website has said.

As the price of oil continues to rocket, having a knock-on effect on the forecourt, is telling US consumers that modern engines mean that many cars which typically use premium can run perfectly well on regular gasoline.

To help, the organization last week released a list of vehicles which "require" premium fuel and a list for which it is just "recommended," meaning that the driver could switch to regular gasoline which is cheaper.

"You'll find that in today's automobiles, advances in engine technology mean that even if the owner's manual recommends premium gasoline, the car will typically run on regular without knocking," said the firm's Consumer Advice editor Philip Reed.

"Its performance will suffer only slightly: perhaps it might be a half-second slower from zero to 60 mph (100km/h)."

Premium fuel generally refers to gasoline with a higher octane rating, used in some high-performance vehicles which require more power - although its availability has led to the assumption that using it somehow increases the power of a car, which isn't always true if the vehicle in question hasn't been designed for it.

Unless specified by the manufacturer, standard fuel will almost always suffice for vehicles, and in many cases it can even be used safely in vehicles where premium is recommended (although using the wrong type of fuel can result in expensive engine damage).

In the UK, for instance, cars must be able to run on both standard and high-octane fuel, according to a technical specialist from British motoring organisation the AA.
