Before I used DFT I had an injector pump rebuilt because it had an injector tube broken. When they took it out it was dirty, and had lots of dirt inside. After using DFT, I went to have another broken injector tube repaired. This time when they took the tube out it was clean. In other words, DFT really cleaned out the system. When I changed the oil in my truck the motor was shaking a lot but when I used Maxilube it changed because it was smooth. The motor was not shaking anymore, so Maxilube really works.
