We'll let the story continue in Tim's words.
"I read a few blurbs about a product that had been around a while on Competitiondiesel.com and Powerstrokenation.com called Rev-X. My initial reaction (like most) was, 'snake oil'! but I figured I had nothing to lose, so I called Dan Wilson, President and CEO of Rev-X products, to get the scoop. I told Dan I was one of the admins on Competitiondiesel.com. We talked at length about his products, specifically the Rev-X lubricant additive (it's not just for oil, it can be added to nearly any lubricant, oil, power steering, differentials, manual transmissions-but not ATF fluid). I was still very skeptical and was blunt. I told Dan that I would like to try it in my own truck and report the results on CompD. He not only agreed, he went a step further. He told me he would supply enough for 10 6.0L Power Stroke trucks as long as all of them were having cold-start issues. All he asked was that all of the participants report back the results. That was confidence! I warned him that the guys on our site were brutal at times. He was unfazed and unwavering in his confidence. We set up the deal and I chose myself and nine other truck owners, ranging from Florida to Alaska and Canada. Long story short, all 10 reported back a 100-percent reduction in stiction and cold-start issues, as well as finding a much smoother running engine, more efficient spooling of the turbo, and a host of other benefits. That was more than I expected by far. These guys were not just anybody-they had credibility. I was a skeptic no more, and a customer for life."
