GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.

Consumer Reports criticizes small turbo engines for misleading performance, fuel economy claims [w/video]

Consumer Reports has taken aim at at small-displacement, forced-induction engines, saying the powerplants don't manage to deliver on automaker fuel economy claims. Manufacturers have long held that smaller, turbocharged engines pack all power of their larger displacement cousins with significantly better fuel economy, but the research organization says that despite scoring high EPA economy numbers, the engines are no better than conventional drivetrains in both categories. Jake Fisher, director of automotive testing for Consumer Reports, says the forced induction options "are often slower and less fuel efficient than larger four and six-cylinder engines."
Specifically, CR calls out the new Ford Fusion equipped with the automaker's Ecoboost 1.6-liter four-cylinder engine. The institute's researchers found the engine, which is a $795 option over the base 2.5-liter four-cylinder, fails to match competitors in acceleration and served up 25 miles per gallon in testing, putting the sedan dead last among other midsize options.
The Chevrolet Cruze, Hyundai Sonata Turbo and Ford Escape 2.0T all got dinged for the same troubles, though Consumer Reports has found the turbo 2.0-liter four-cylinder in the BMW 328i does deliver on its promises. You can check out the full press release below. You can also read the full study on the Consumer Reports site, or scroll down for a short video recap.

Chevy might've pulled out of NASCAR if it weren't for new Gen 6 car

We've been on the fence with NASCAR for some time now. On one hand, it's some of the closest racing anywhere in motorsports, with actual passing and door-handle-to-door-handle action as a matter of course. But on the other, it's become template racing - a personality-driven sport more about the drivers than any sort of loyalty to a particular automaker. The Car Of Tomorrow format really rammed that message home, with a racecar's identity coming down to little more than headlamp stickers slapped on the nose. That's not necessarily a bad thing in and of itself, but we've wondered for some time what's in it for the automakers, who pay big money to stay in a series that has had little increasingly little do with street car sales, let alone innovation.
Apparently General Motors was beginning to wonder the same thing. In a new ESPN report, Rick Hendrick, team owner of Hendrick Motorsports, suggests that GM would have seriously considered leaving NASCAR if it wasn't for the move away from the COT to the new Gen 6 racer. According to Hendrick, GM North America boss Mark Reuss spearheaded the charge away from the 2007 COT and toward a racecar with clearer automaker ties - cars like the new Chevrolet SS racer shown above.
