EACH QUART- $5.99 HOWES DIESEL TREAT. The introduction of ULSD has created several serious problems for diesel powered vehicles. During the refining process of removing sulfur, important properties such as lubricity and BTU's are reduced. HOWES DIESEL TREAT will help prevent your diesel fuel from gelling in cold weather and correct the inherent problems caused by ULSD fuel. HOWES DIESEL TREAT replaces the lost lubricity and compensates for lower BTU's by improving combustion, resulting in more power and better MPG's. HOWES DIESEL TREAT demulsifies or displaces water out of the fuel, leaving only pure fuel to burn. As the vehicle moves and agitates, water is easily removed by the water separator. Products that emulsify or disperse water into the fuel are usually alcohol or solvent based and can further damage key system components by allowing water to pass through the fuel water separator. Since water is abrasive, it tends to score or wear down the close metal to metal tolerance of the injection system causing smoke and loss of MPG's.The perfect solution to prevent these problems is to treat each purchase of ULSD fuel with HOWES DIESEL TREAT.
