Premium Gas A Con?
What Car? [via The Daily Record] says premium petrol is a rip-off, providing neither extra power nor superior gas mileage. The UK consumer magazine paid a lab to test various premium grades against their lowly counterparts. The lab concluded that premium petrol purchasers may eke out a few more miles to the gallon, but the cost (up to 30p more per gallon) outweighs the benefit. In specific, they claim that Shell's V-Power petrol couldn't quite match the mileage provided by regular: 22.9mpg to 23mpg (which is well within the margin of error). The article fails to mention that certain car manufacturers require premium unleaded for a reason; the knock sensor will smooth things over, but you'll get pitiful gas mileage and probably damage your engine over the long run.
