Feel free to move this thread, i wasnt sure where to put it but 6.0's have the most problems. I was watching Truck U and they advertised a product called Hot shot's Secret. It is an oil additive similar to rev-X i believe specifically for injectors and general cleaning of the engine. . I was wondering if anyone has ever used this. I'm not sure how new it is but the company is based only 100 miles from me and i didnt know they existed. Thanks for any replys.
