There is a good article on the future of diesel engines in popular mechanics this month, the article clearly states that the united states has the worst diesel fuel by far.

It appears The Duramax HPCR is or could be suffering the rath of the poor quality ... Worlds biggest Auto maker GM will hopefully make some corrective measures ....


The rest will simply grasp the bull by the horn thru Message Board info and trial and error testers and decide on whats best to use for better filtering systems available in the aftermarket to us ...


Can't wait to get my 2um on when I find the time ...
