Default Fouling glow plugs

My latest problem with this piece of ****. My savage X 4.6 rtr keeps fouling glow plugs. New plug will run 10 or fifteen minutes then die. It will restart but soon as igniter is removed it dies. I have went thru 5 new plugs, Tired to run it lean, rich, no air filter oil, different fuel all no difference. Any Ideas?

If your to rich uan saturate the coil and if your to lean you can burn out the coil both causeing the plug to die

Plugs are black and oily. Could it be that I am using to much filter oil? I recently started using Factory Team Foam Pre-filter Treatment by Team Associated as my filter oil. LHS said I should use about 3-5 drops. I have been pouring some into plastic bag with filter and working it in. The stuff is way sticky.
