Lubro-Moly diesel purge. Diesel Roto Rooter! Clean the crap out of your injectors and pump! This diesel fuel purge is strong medicine for sick diesels. Clears injector nozzles in minutes. Eliminates "nailing", knocking, and shaking. Restores power, eases starting, reduces smoke and particulates. To restore sick diesels to new health and vigor, simply run one or two cans of Diesel Purge through the injection system. Use this stuff straight. Don't dilute it. You stick your supply and return lines from the fuel pump into this can and the can replaces your fuel tank for the 15 minutes it takes to burn this stuff straight. If you don't want to do that, simply add it to your fuel and it will clean your fuel system as you drive.
After using VW diesel purge, maintain the condition of your fuel and fuel system components with Stanadyne.
