On-site, mobile diesel fuel polishing & tank cleaning service. Our fuel oil polishing process connects to the fuel system, removes bottom water, sludge, entrained water & filters solids & biological residue through filters that remove particles down to 1 micron. We restore contaminated diesel fuel to a better-than-refined condition, a degree of quality that meets or exceeds recommendations of diesel engine manufacturers. This prevents fuel filter clogs & helps ensure reliable operation of diesel engines.
