Provide maximum lubricity Advanced polymer technology keeps lubricants in place even under high stress conditions. The real cost of fuel* Improves fuel quality and enhances engine performance year-round. Properly-treated fuel will increase hours or miles per gallon, reduce emissions and lower repair and part replacement costs Untreated Diesel Fuel Treated Diesel Fuel TODAY ASSOCIATED COSTS ASSOCIATED COSTS Maintain clean system Advanced detergents prevent the formation of deposits to keep equipment working at peak performance. Control contaminants and oxidation Superior additive technology eliminates the harmful effects of contaminants and reduces oxidation. This increases equipment efficiency and lowers power consumption.

Decline in Cetane Number EPA Emission Requirements PROBLEMS PROBLEMS Problems With Diesel Fuel Declining quality and rising costs Problems With Diesel Fuel These problems cost you money Problem 1 / Low Cetane The Engine Manufacturing Association (EMA) requires a minimum of 50 cetane for optimal performance. Below 50 cetane fuel causes: • Increased stack emissions • Poor combustion efficiency, loss of power and lower mileage • Harder starting • Detonation wear - from violent explosions which damage piston heads, rings, valves and cylinder liners “Over the last two decades , the cetane number and the API gravity, the basic measures of crude oil quality have declined” Diesel in the US Decline in Cetane Number $ USD GALLON OVER TIME AVERAGE CETANE LEVEL OVER TIME Society of Automotive Engineers (SAE), Bulletin 872243 “Diesel fuel quality has deteriorated for the past 20 years and is expected to continue this trend for the foreseeable future” American Society for Testing and Materials (ASTM), Pub. 10056 Problem 2 / Poor lubricity To reduce stack emissions, the EPA mandates Ultra-Low Sulfur Diesel fuel contain no more than 15 ppm of sulfur • The removal of most of the sulfur, the natural lubricant in diesel fuel can cause both mechanical and chemical wear • Worn injection systems result in poor fuel economy, excessive stack emissions, equipment down time and engine repair cost Fuel quality has deteriorated and costs continue rising • Rougher grades of crude are being extracted • Producers take shortcuts in refining • The best parts of crude are being used to produce gasoline, jet fuel and kerosene • The refining process used to meet new EPA regulations on ultra-low sulfur diesel (ULSD) results in reduced fuel economy and severe fuel system wear Problem 3 / Contaminants Contaminants form deposits: Today’s diesel fuel contains high levels of contaminants - like wax and acids that clog injectors and contribute to air pollution Problem 4 / Water contamination + biological growth • Condensation, rainwater and seepage cause water contamination in fuel • Bacteria and fungi enter fuel through water contamination or air vents Fuel quality deteriorates every time it’s handled EPA Emission Requirements EMISSION LEVELS OVER TIME Problem 5 / Exhaust emissions Exhaust emissions have become one of the major problems of the 21st century. The best solution to better engine performance is to consistently improve the quality of the fuel that we run through our equipment OIL WELL REFINERY PIPELINE TERMINAL FUEL JOBBER DELIVERY TRUCK STORAGE EQUIPMENT Industry surveys show that low quality diesel fuel is the no. 1 cause of poor engine performance
