Amercian survey deals with prices at the pump in the U.S.
Are You Throwing Away Dough at the Pump?
This will wake you up. The American Automobile Association says US drivers blew about $2.1 billion on higher-octane fuel than their cars need, as most engines – about 70% – only require regular unleaded fuel. An AAA engineering and repair expert says, “Drivers see the ‘premium’ name at the pump and may assume the fuel is better for their vehicle.” But it’s not. High-octane fuels are able to withstand more compression without combusting, making it critical in high-performance engines. But while cars on the “premium required” list need that higher-grade fuel to prevent engine damage – only about 16% of Americans drive those types of cars. Cars on the “premium recommended” list are likely just fine with regular gas, thanks to advanced engine technology. The engine won’t suffer, and the worst effect may be a slight speed reduction – as in a half-second when going from zero to 60mph. And while some drivers may still buy premium once in a while to flush out the tank, experts note all gas grades have an ample amount of additives for cutting down emissions and keeping engines in tiptop shape. AAA says a better bet is taking your car for regular maintenance checkups and keeping away from low-quality gas, which is very different than regular gas from a top-tier brand. (CNN Money)
