If my Duramax is close to 15,000 miles since last fuel filter replacement it starts being sluggish and a little loss of power. For those with GM diesels...change the fuel filter at 15,000 or suffer the results.
New fuel filter (15 mintues exchange) makes all the difference.

If you want to get more life out of that expensive GM filter, you can add a Cat pre-filter system. I use one on my truck. The Cat filter is also 2 micron and about 4 times the size of the GM filter. It costs a lot lets too - around $15. I don't think you get diesel fuel too clean!

One place that sells this kit is here: http://nicktane.com/osc/product_info.php?products_id=28
