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.

These are the 'Greenest' and 'Meanest' cars in 2015

As has become tradition, the American Council for an Energy-Efficient Economy (ACEEE) has come up with a ranking of what it refers to as the "greenest" cars of 2015, and, by way of contrast, a list of the so-called "meanest" cars, so those who value eco-friendliness over all else can choose which vehicles they should or should not consider buying. As you may expect, electric cars make up the majority of the greenest cars on the list, but, perhaps surprisingly to many, the Tesla Model S didn't make the cut. It's worth noting, too, that where the electricity an owner uses to charge their electric vehicle has a big impact on its overall environmental impact. "A car that is charged using electricity generated from natural gas or renewables is going to have significantly less impact on the environment than one charged on a coal-heavy grid," says ACEEE lead vehicle analyst Shruti Vaidyanathan. The ACEEE's list for 2015 looks very different than it did in 2014. It's an interesting collection, though – and we're sure this goes without saying, really – we'd recommend doing a bit more research into each vehicle and how it might fit into your daily life before making any purchase decisions.

Four recreational vehicle companies in Texas have settled with the EPA over illegal import and sale of off-road vehicles. The 4,000-plus Hammerhead brand vehicles in question were imported without the proper certification, a violation of the Clean Air Act. Some vehicles lacked proper emission control equipment or were manufactured by a company not listed on the certificate application. The settlement totals $560,000 in civil penalties for the companies involved. Read more from the EPA. The Iowa Supreme Court has upheld the state's natural gas tax, which was challenged by the ethanol industry. Ethanol producers, which use natural gas to make ethanol, argued the complicated tax was unconstitutional, as it forced certain plants to pay more than their competitors. Taxes vary by location, and some plants have to tap into interstate pipelines at much higher tax rates rather than get it from a local utility. Now, ethanol producers will work to change the law. "My hope is that people understand that, something may be constitutional but that doesn't make it good public policy," says Iowa Renewable Fuels Association Executive Director Monte Shaw.

Valeo says Audi will launch a vehicle using its electric supercharger next year, with other reports suggesting that car will be the Audi Q7. The company says other unspecified automakers will also use the technology in their vehicles. While the electric supercharger adds to the vehicle's cost and electric energy use, it can improve fuel economy by as much as 20 percent. Read more at Automotive News Europe.
