opti lube fuel treatment

any one tried this fuel treatment.

I have been using Diesel Kleen summer/winter blends and have had no problems.

but you know me, do to much reading, saw where this stuff had a better rating, but boy o boy it should, by the time I got it (ups) quite a bit more $$$$$$$

has anyone tried this stuff Opti Lube XPD per the bottle it can be used summer winter.

Thanks,

will wait for your response before I pour any in the tank.

dodge diesel 2005 model, runs greats as we speak and would like to keep it running good.
