The automotive industry wants to make 95 octane gasoline the new normal for the United States and it has taken its case to Washington. On Friday, Dan Nicholson, General Motors’ vice president of global propulsion systems, told the House Energy and Commerce Committee’s environment subcommittee that switching to 95 octane would align the U.S. with Europe and is one of the most affordable ways to boost fuel economy and lower greenhouse emissions.

Affordable for automakers, that is. Because there is no reason to think your local gas station will suddenly do you a solid and price 95 octane lower just because 87 is gone.  (Read More…)

1-Ethanol-Gas-006

Like something from the Nixon era, the U.S. Southeast is currently in the grips of a gasoline shortage, all thanks to the shutdown of the Houston-to-New York Colonial Pipeline. North Carolina and Virginia have declared a state of emergency as gas pumps dry up.

Even TTAC’s Bozi Tatarevic can’t find premium unleaded to save his life. His WRX’s tank runneth dry.

The sudden gas crisis provides a perfect backdrop for a study by the American Automobile Association showing that 16.5 million Americans gassed up their vehicle last year with octane they didn’t need. (Read More…)

Speaking at a conference this week, EPA exec Christopher Grundler said automakers have asked for higher octane fuels for higher compression tolerance and more powerful engines, Automotive News is reporting.

Speaking at the CAR Management Briefing Seminar series, Grundler said the EPA has the authority to regulate fuel, but that the agency would investigate whether it would make sense to offer the higher-grade fuel. Grundler is the agency’s director of the Office of Transportation and Air Quality.

(Note to Grundler: You seem like a smart guy. Why can’t we all have race fuel all the time?)

Hi Sajeev,

I have a Piston Slap question: Most of the gasoline sold here in New Mexico is high altitude gas, meaning that Regular is 86 octane, Midgrade is 88, and Premium is 91. The owner’s manuals for my ’06 Corolla and my wife’s ’08 Hyundai Tucson (try not to be jealous :-) ), calls for 87 octane fuel. Am I OK to use Regular or should I take the manuals at face value and pay a dime more per gallon for Plus? (Read More…)
