"We are under strict opacity laws...this fuel conditioner has
accomplished cutting our opacity 40 to 60 percent.... We have experienced a good
savings in fuel consumption... I do find a considerable savings when it comes to
injection pump repairs and injector maintenance. We no longer pull them down on
PM intervals due to the reduction in carbon on the injector nozzles... This
product has lived up to my expectation and I would highly recommend Hammerdown."
"I have been a Marine Engine Engineer for 30 years and am well aware of fuel additives. They either work partly or not at all....
"There was no wear in the engines and the normal build up of hard carbon was noticeably missing. With 23,000 hours of operation this was unusual....
"The main contributing factor for the excellent condition of his and the lack of fuel problems: bacteria, sludge, etc. is directly related to the continued use of DFT #1500.
"40,000 engine hours of operation, without any adverse effects to the engine or the fuel system, says DFT #1500 ... deserves recommendation for use. I recommend to any and all interested parties the use of DFT #1500, a fuel additive that works."

"Use of this product [DFT #1500 "Hammerdown® "] will not affect the warranty of any Cummins component."

"Since you introduced DFT#1500 "Hammerdown® " to me over two years ago, I have had the opportunity to see the effect of its use both in my personal vehicle and in Detroit Diesel engines. I have never seen any damage to any engine. And since the evidence suggests that your product helps correct fuel related problems., I have been willing to recommend that you contact those Detroit Diesel owners who experience such problems."

"Provided the manufacturer's instruction are followed, we have nothing against the use of DFT #1500 "Hammerdown® " [during the warranty period]."

"Treated fuel would be well within the maximum allowable under aviation turbine fuel specification limits and/or acceptable industry standards.... It is our opinion that continued use of fuels treated with DFT #1500 Hammerdown® in the prescribed manner would not be detrimental to engine parts or operation."
