Americans waste $2 billion a year on pricey premium gas

Surprise! The new Prius is absolutely fun Americans ashen over $2 billion aftermost year putting big-ticket exceptional gasoline into cars that don t charge it, the auto buying accumulation AAA said Tuesday. Most car engines in America are advised to run on approved gasoline and, admitting the superior-sounding name, exceptional gasoline provides no account over cheaper approved gasoline in those engines. Exceptional has a college octane appraisement than approved gas. That agency it s able to abide college pressures central the engine. Engines advised to run on approved don t accomplish at pressures aerial abundant to crave the added octane, so putting exceptional ammunition into an agent that doesn t crave it is artlessly a decay of money, AAA said. Drivers see the premium name at the pump and may accept the ammunition is bigger for their vehicle, said John Nielsen, AAA s managing administrator of Automotive Engineering and Repair. AAA cautions drivers that exceptional gasoline is college octane, not college quality, and urges drivers to chase the owner s chiral recommendations for their vehicle s fuel. About 70% of cartage now on the alley crave alone approved fuel, AAA said. Still, about 16.5 actor drivers unnecessarily abounding up with exceptional at atomic already aftermost year, according to AAA. That agency Americans spent added $2.1 billion on added big-ticket ammunition for no reason, the accumulation calculated. On average, exceptional costs about 50 cents a gallon added than regular, AAA said. Related: World s fastest VW Beetle goes 205 MPH About 16% of Americans drive cartage that absolutely do crave exceptional fuel, though. These are mostly high-performance or affluence models. Application cheaper approved ammunition in these engines can account accident In tests conducted forth with the Auto Club of Southern California s Automotive Research Center, AAA ran approved and exceptional fuels in assorted altered car engines advised to run on regular. Application exceptional fuels in these engines did not aftermath added horsepower, bigger ammunition abridgement or lower tailpipe emissions. In some vehicles, exceptional ammunition is recommended but not required. Those cartage may accomplish with lower ability or ability application approved fuel. Still, it may not aching the agent to use approved in these cartage provided that no agent knock is heard, AAA said. If an abnormal animadversion or banging complete is heard from the engine, as it ability be beneath decidedly abundant use, exceptional ammunition should be added to the catchbasin as anon as possible, Greg Brannon, AAA s arch of Automotive Engineering, said. As always, he said, drivers should argue their owner s chiral about which blazon of ammunition is best. Photos: Coolest cars for $18,000 A abstracted AAA abstraction appear beforehand this year showed that cheaper off-brand gasolines can abuse agent achievement in the continued term. This is a abstracted acumen from exceptional vs. approved gasoline, though. In that study, AAA was comparing gasoline awash by altered retailers. AAA begin that gasolines awash by no-name gas stations — ones that weren t affairs a above cast like Exxon Mobil, BP, Shell or Chevron — could account austere build-ups of agent deposits over aloof a few thousand miles. Such carbon deposits are accepted to abate ammunition economy, access emissions and abnormally appulse agent performance, decidedly on newer vehicles, AAA said. This can appear because the cheaper brands of gasoline may not use engine-cleaning bactericide additives begin in above name-brand gasolines. Editor s note: Correcting typo in Greg Bannon s name.
