GM to reprogram some oil-life monitors

This story originally appeared on Automotive News General Motors is warning owners of almost 800,000 2010-12 vehicles that they may need oil changes more frequently than the onboard oil monitoring systems are telling them. After high warranty claims on several models with four-cylinder engines, GM will reprogram software to make oil change warning lights go on sooner. The change only affects 2010-2012 Chevrolet Equinox, GMC Terrain and Buick LaCrosse and Regal models with 2.4-liter LAF and LEA four-cylinder engines.

Mountune will upgrade your Focus ST, Fiesta ST

UK-based Ford tuner Mountune set up shop in the U.S. just a couple months ago, and is already offering upgrades to the Ford Focus ST and the Ford Fiesta ST. Mountune is Ford's official partner in Europe, and their experience goes back 30 years Mountune comes from a slightly different branch of Ford tuning that North American buyers are used to -- their specialty has been tuning Ford's smaller cars in Europe rather than muscle cars, and they've worked on everything from Escorts to Focuses (though perhaps not the Escorts and Focuses that we're used to).
