Platinum Contributing Member steve from amherst Posted October 13, 2019 Platinum Contributing Member Share Posted October 13, 2019 While the ramifications of the Volkswagen Dieselgate scandal continue to be felt, it seemed like the dark fog over diesel technology was finally lifting. But now General Motors is dealing with its own situation regarding diesel engines. The Detroit News reports that GM is now facing a class-action suit alleging its 6.6-liter Duramax engine found in 2011-2016 Chevrolet and GMC models is not compatible with US diesel fuel. Details of the lawsuit, which was filed this week, say GM sold "hundreds of thousands" of engines containing a Bosch fuel injection pump that pumps metal shavings into the fuel injection system, ruining both the fuel system and the entire engine. American diesel fuel is thinner than its European counterpart, allowing for air pockets that cause the metal to rub against metal and create shavings. "The pump secretly deposits metal shavings and debris throughout the fuel injection system and the engine until it suddenly and catastrophically fails without warning," the lawsuit alleges. "Such catastrophic failure often causes the vehicle to shut off while in motion and renders it unable to be restarted because the vehicle's fuel injection system and engine component parts have been completely contaminated and destroyed. GM promised consumers the continued reliability of their diesel engines, but with increased fuel efficiency and power at greater fuel efficiency. However, this came with a hidden and catastrophic cost that was secretly passed on to consumers," the suit claimed while also referring to the engines as a "ticking time bomb."

hayward Posted October 13, 2019 Share Posted October 13, 2019 how about the lack of sulfur the epa mandates in the fuel thats supposed to lubricate the pumps in the first place? 2 Quote Link to comment Share on other sites More sharing options...

Sulfur isn't a lubricant in diesel. Neal Quote Link to comment Share on other sites More sharing options...

Gold Member BOHICA Posted October 14, 2019 Gold Member Share Posted October 14, 2019 (edited) Ultra low sulphur was around and mandated long before duramax’s started chewing through fuel pumps..... It’s a gm issue not a fuel issue Edited October 14, 2019 by BOHICA Quote Link to comment Share on other sites More sharing options...

The processing used to remove sulfur also removes lubricant components of diesel, but sulfur itself isn't a lubricant. Neal Quote Link to comment Share on other sites More sharing options...

Ez ryder Posted October 14, 2019 Share Posted October 14, 2019 Sulfur acts as a lubricant in diesel, and by lowering the sulfur content there is a corresponding drop in the fuel's lubricity." Quote Link to comment Share on other sites More sharing options...

You are the one who doesn't understand what's going on bro. Perhaps you need to do some research before spouting off. Neal Quote Link to comment Share on other sites More sharing options...
