You may very well be right. I gues I should not of bought my second duramax, some people have had injector problems they all must have injector problems. You are saying that it is all bad and that is the point I argue.

We have to be educated on the fuel we run, bio-diesel or not.

How do you explain the 1000's of fillup and the 100,000's of miles driven and not 1 single problem?

I believe your numbers are right and this does raise the white flag and I will be much more cautions on the road to use bio-diesel. The only time I am on the road and have to fill up is when I am towing and I look for high traffic fill stations.

The white flag is waving and know your source of fuel or bio-diesel.

Thanks for the info George. I will see if I can get analysis numbers.
