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.

GM 6.2L EcoTec V8 rated at 21 mpg by the EPA

General Motors is already laying claim to best-in-class power for its new 6.2-liter V8 that will be offered in the 2014 Chevy Silverado and GMC Sierra this fall, and now it has released fuel economy numbers for the big engine. Available as an option on the Silverado LTZ and High Country (shown above) models as well as the the Sierra SLT and Denali trims, the 6.2L EcoTec3 V8 will return 15 miles per gallon in the city and 21 mpg on the highway on rear-wheel-drive trucks; these numbers drop by one mpg each on four-wheel-drive models.
These estimates are in addition to the engine's 420 horsepower, 460 pound-feet of torque and max trailering capacity of 12,000 pounds, and considering all that power it's not terribly far away from the fuel economy of GM's equally new 4.3-liter V6 and its rating of 18 mpg city and 24 mpg highway. This announcement comes just days after a report indicated that GM is unable to keep up with the demand of the 5.3-liter V8 in the fullsize Chevy and GMC trucks due to supplier issues. GM's official press release for the 6.2-liter V8's fuel economy is posted below.

A spotter's guide to Super Bowl LIV car commercials

Set to kick off on Fox at 6:30 ET on Sunday, February 2, from Hard Rock Stadium in Miami, Florida, the big game will feature the Kansas City Chiefs and the San Francisco 49ers. Throughout Super Bowl LIV, viewers will see about 50 commercials, each of which costs as much as $5.6 million per 30 seconds, according to AdWeek. Originally, there were more than 77 ad slots, so several companies could be paying well more than $10 million for a single, longer commercial. Numerous car companies have already announced their commercials, or their intentions to show commercials, during the game. Here's a roundup of the ones we know about so far. During the game on Sunday, we'll be livestreaming and adding links to the new commercials as they become available, so check back with us for that post.  Audi: E-Tron Sportback Maisie Williams has experience wearing many faces, and in Audi's Super Bowl commercial, she does her best Elsa impression. In the spot, titled "Let It Go," Williams faces the rigorous task of getting through L.A. traffic, but she's alleviated by the comfort of the Audi E-Tron Sportback electric crossover. The commercial is meant to signal the company leaving its gas past behind and moving forward to a sustainable future.  Genesis: GV80 Genesis makes its Super Bowl debut with a commercial that will show its all-new SUV, the GV80, to viewers around the world (many of which will be seeing the vehicle for the first time). The ad features Chrissy Teigen and John Legend as the purveyors of "new luxury," while "old luxury" is left for the birds. GMC: Hummer General Motors is bringing back the Hummer nameplate as a premium electric GMC truck. GM says it will have 1,000 horsepower and will be capable of going zero to 60 mph in three seconds. GM brought in NBA legend and Hummer fanboy LeBron James for the debut commercial. Hyundai: Sonata Hyundai is known for bringing in the big-time celebrities for its commercials, and 2020 is no different. A new advertisement called "Smaht Pahk" features John Krasinski, Chris Evans, and Rachel Dratch, all three of whom are from the Boston area. The trio gets into full character as they discuss the new high-tech parking feature on the redesigned 2020 Hyundai Sonata, and David Ortiz makes a cameo at the end. Even when New England isn't in the Super Bowl, New England is in the Super Bowl.
