I find it hard to believe that an additive, can increase the compression on a Diesel motor... on a gasser the compression was probably down around 60 psi and it bumped it up to what, 80, 85? below 270psi it is nearly impossible to start a Diesel... what additive can help at those pressures reliably? most Diesels lose compression due to valve wear, or ring slop, not grooves in the soft pistons, or cylinders. I think the best that can be done with out overhaul is fresh clean oil... and frequent oil changes.
