Fuel consumption: Feeding your car for maximum performance
Does your fuel make your engine knock and ping?
By Angela Tague
If you're in the habit of rolling up to the gas pump on fumes and filling the tank with premium gas, it's time for a little automobile 411. Your car's fuel consumption of premium or regular gas determines the car's performance--not fuel efficiency.
But, what about performance?
The high-end BMW and Saab used in the experiment were less powerful when fueled with regular gas. The lesson? Stick to premium gas when you want your car to operate at its maximum performance, according to the article. High-compression engines designed to run on premium fuel will operate more effectively on the higher-grade gas. This means less knocks, pings, rattles and a smoother rev of the engine. These findings are inline with Scientific American's advice: premium fuel is best for premium vehicles.
Senior Consumer Advice Editor at Edmunds, Phillip Reed states in his article, "To Save Money on Gas, Stop Buying Premium," that vehicles running on regular fuel may notice a little less get-up and go than those consuming premium gas, to the tune of being a mere 1/2 second slower when accelerating from zero to 60 mph.
And the results are...
Since the differences between using regular and premium fuel are minimal, the take-away is this: use premium gasoline in high-end vehicles and regular in everything else. If you notice lots of knocks and pings when starting up your car, switch to premium fuel.
