Dear Sir:

I am forwarding this letter to you to advise you that after having used your ENERGY+ product in our Superior boilers, I am very pleased with the increased performance and efficiency that have resulted from combining your ENERGY+ additive with the #2 fuel oil which is burned at our County College. Over the past several years various types of fuel oil additives have been tried all of which were to have increased the efficiency of combustion, however, none of these additives came up to the level of efficiency that was advised by the supplier. This has not been the case with your product. Your product meets or exceeds the suggested savings and in my opinion it is a product that will continue to be used here at our County College.

Prior to using the fuel additive during a normal heating season it was necessary to clean our boilers at least once during the winter months. Usually after the first, second or third months of winter operation stack temperatures increased to between 450 and 500 degrees, which indicates a high level of carbon in the fire tubes. Since we have been using your product we have not had to clean the boiler tubes during this heating season and in general our stack temperatures have not exceeded 360° F.

During this past heating season we have saved more than the recommended 5% in fuel consumption with these savings being attributed to the use of the ENERGY+ fuel additive. You definitely have a satisfied customer at this College as was evidenced by the purchase of additional ENERGY+ fuel additive for the remainder of this and subsequent heating periods.

Very truly yours

William

Director of Plant Operations
