Just wanted to let you know that I have found SFR to be a very good product. Although I was somwhat skeptical at first, SFR has proven to be good maintenance and fuel saving oil additive.
In our diesel pick-up trucks fuel mileage has increased by 15%, from 13 mpg to 15 mpg. Also they are much easier to start during cold weather.
Fuel mileage in our tanker trucks has increased by 10% with a fleet of forty vehicles our fuel savings should be very substantial.
I also tried SFR in our air compressor with some impressive results. The compressor now runs much quieter and seems to work with less effort.
Thanks for a great product and I am sure I will be calling you again in the future to order more SFR. Sincerely, David Steneken, Mechanic Tru-Green/Chemlawn, Rochester, NY.
