Carbon cleaning preformed on my 1998 D5M Cat dozer and 2005 312CL Cat excavator. Immediately noticed minimal emissions, so I feel that the fuel is being burnt more efficiently. More power with less fuel! Also, after 100 hrs of service, I changed oil. Normally the oil color ranged from dark brown to almost black. Now the oil is a lot cleaner than before. Very happy with results! It works for two machines with 10,000 hrs and 6,000 hrs respectively. Thanks Terry and Jared!Service: General repairs & maintenance

We have had four of our diesel vehicles serviced. I was very pleased with the service as all four vehicles have shown better throttle response as well as better fuel economyServices: Carburetor cleaning, Exhaust, Auto engine tuningServices: Carburetor cleaning, Exhaust, Auto engine tuning
