## AAA tests show premium fuel benefits some vehicles, but comes at a high cost

##### 12 December 2017

Last year, nearly 1.5 million new vehicles sold in the United States recommend, but do not require, premium gasoline. The trend toward recommending or requiring higher-octane fuel continues to rise as manufacturers work toward meeting stringent CAFE (Corporate Average Fuel Economy) standards. According to new research from AAA, premium gasoline... Read more →

## Researchers at KAUST, Saudi Aramco evaluating low-octane fuels for gasoline compression ignition engines

##### 27 November 2017

Gasoline compression ignition (GCI) is an experimental engine technology that could consume 25% less energy than a conventional automobile engine. (Earlier post.) GCI uses a gasoline-type fuel, but rather than ignited with a spark, it is compression-ignited like diesel. GCI engines operate at higher compression ratios than conventional gasiline engines,...
