I do not believe it does but it is the only product the dealer offers, officially. There was some seepage from the diff. tech shared with me and i observed over the last year or so. I asked him how much he removed and he could not say as the measure was just "in the bucket". However, I am sure that the BG will be filled to the correct level and amount. I am hoping that it may qiuet what is perceived as driveline noise.
