Thanks, gchavez,

Thats really good documentation. I just bought a couple of 96 oz jugs of Diesel Kleen last week from WalMart for about the same price, 1 white and 1 gray. I haven't tried them yet, until I finished my Shell DFA, which I did tonight. So next fill up I will add the Diesel Kleen. How much did you add per tank? Also how big is your tank?

At the least I am glad to see the Shell was helping, though not as good as the Diesel Kleen, it looks like.

Thanks again for sharing those kind of details with us. Keep up the good reporting.....
