Thayer,

I would be remiss if I didn't remind you that the Basics ,Like Valve adjustment
and Correct Injector "Pop Off" pressures
(ALSO Compression differences between cylinders ,NOT related to Valve Adjustment) WILL NOT BE CORRECTED BY ANY ADDITIVE...
Redline,Lubri-Moly,Etc.,Etc.

So if you have one of those underlying Mechanical problems and the Redline,etc.Didn't provide the relief expected or anticipated ,the tendency
would be to blame the lack of results on the Additive rather than the
Lack of Maintenance.
