Thanks so much for the professional service your company provided last week with getting my tanks cleaned and diesel fuel polished. I didn’t even realize the risk I was running until they showed me the free samples from my tanks. Thank you for saving me from a serious issue in the future. I would recommend anyone call them for a free sample and estimate.

I never realized how dirty diesel fuel could get until I saw CFSs free sample. (They will come out and do this on site with your own fuel.) After they polished some of the fuel, it looked like a night and day difference and really made it stand out how dirty the fuel really was. To think this fuel was going into equipment is a scary thought. I cant imagine how much this will save in the long run. Amazing customer service as well!
