Has anyone here had to replace their injectors on their 01-04 LB7 duramax motor. On the site dieselplace.com it is a very common problem and I was wondering what effect positive or negative b100 might have on my newly acquired 02 duramax.

I have 01 duramax, GM replaced all the injectors for free because 1 failed at 90,000 miles.
Have been using approx. B50 for 75000 miles no problems. Make sure you know how to change filters on the road, you might plug a filter when the petro junk gets cleaned out of tank and lines. Filters can be changed in about 5 minuets. Always know the quality of your fuel. Bad fuel will cause problems.
