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.

2017 Buick LaCrosse First Drive

The 2017 Buick LaCrosse seems destined to never get the credit it deserves. It's bound to be dismissed as just another full-size sedan relic, ignored by those who habitually visit their Lexus dealer every few years for a new ES. This new LaCrosse will inevitably be overshadowed in the Buick showroom by SUVs and never fully appreciated by the majority of its buyers who simply want a big, comfy, and quiet car. That destiny would be a shame. The completely redesigned LaCrosse is now a legitimate luxury car, not because advertisements say it is, but for the way it drives, the way it looks, and the way it cossets you inside. The former is really the most impressive, since it's also the most surprising. During the LaCrosse press launch in Portland, Oregon, Buick boasted how comfortable and exceedingly quiet the car is, and indeed, it isolates road imperfections and allows for a pair of low talkers to converse in subdued tones. The big Buick sedan's low-effort steering will also satisfy the nice-and-easy tastes of most drivers. The best way to describe driving the LaCrosse is "unwaveringly pleasant." Yet, during that pleasant drive, road dips and mid-corner undulations don't make the comfort-tuned suspension bob and bound like its competitors might. Its body control and generally planted nature encourage speeds and confidence to creep ever so higher through successive sweeping corners on Oregon's densely forested Mist-Clatskanie Highway. Even that low-effort steering demonstrates precision, linearity, and just enough feedback to further spur on such a pace. This unexpected capability is best observed on cars equipped with the optional 20-inch wheels, which supplant the standard 18s and, more importantly, bring with them Continuous Damping Control (CDC) and GM's HiPer Strut front suspension, which is designed to quell torque steer and further improve cornering grip. You don't even have to engage CDC's firmer Sport mode to appreciate the LaCrosse's surprisingly sharp road manners. "We unleashed the engineers," chief engineer Jeffrey Yanssens said after our test drive. "I told them, 'I don't care how much it costs. I want you to know your system and I want your system to be the best it can be. What do you have to do to make that happen and what can I do to enable you to make that happen?'" Yanssens is honest and clearly proud of his team's work.

Question of the Day: Best recipient for supercharged GM V6?

The good old Buick V6 engine was built from 1961 through 2008 (including a decade of production by Kaiser-Jeep) and went into way too many General Motors vehicles to list here. In 1991, the supercharged version of the 3800 was introduced, with a Roots-style Eaton blower on top, and now you can find these engines in just about every junkyard in North America. The 3800 shares a bellhousing pattern with the also-made-by-the-zillions GM 60° V6 engine, which means that it will install (with varying levels of sledgehammer clearancing and/or axle mix-and-matching) into plenty of GM vehicles that never received the 3800 from the factory. That means one thing: engine swaps! An excellent example of this is the 1992 Chevrolet Lumina APV "Dustbuster" minivan, which is a fully caged high-performance road-racing machine that features a supercharged 3800 and 5-speed manual transmission under its long, vacuum-cleaner-snout-like hood. The RaceVan, in Springfield Monorail livery, will compete this weekend at the Michigan 24 Hours of LeMons race with Autobloggers Mike Austin, David Gluckman, and Alex Kierstein at the wheel. My personal choice for supercharged 3800 power, though, has to be the Cadillac Cimarron, preferably the not-so-sought-after Cimarron d'Oro Edition. Some bashing and welding and cutting and pasting and this lightweight Cavalier sibling could have well over double its original horsepower. So, what's your blown 3800 engine-swap choice?
