The Ultra-Lowdown on the New ULS Fuel

Written By: Xtreme Diesel Performance

    Farmingdale, NJ - Ready for the newest generation of Diesel? Going green doesn't just mean buying a hybrid and moving to San Francisco. Keep your truck, and look cool while protecting our environment. The new requirements for Ultra Low-Sulfur Diesel require the sulfur level to be dropped 97% from the current level that was mandated in 1993. The new legislation requires all Model Year 2007 diesel engines to use high-efficiency catalytic exhaust emission control devices. What does this mean for trucks built before 2007?

     Concerns for this new product range from lubricity to cost. In order to reduce the sulfur level to 15ppm (the new standard) manufacturers are using the old method of 'hydro-treating', but increasing the duration of the process; called 'Severe Hydro-treating'. In actuality a lower sulfur content does not present any risk to your vehicle; the problems occur in the removal process. The 'Severe Hydro-Treating' robs the fuel of naturally occurring Lubricating, Viscosity, and Stability properties. To counteract the depletion of these properties, artificial lubricants must be added (added cost as well.) Here lies another problem, most refinery's are unwilling to add the lubricant due it its potential harm to the pipelines. So in order for the lubricant to be added it will be up to the Terminal operator or Oil jobber to add the treatment additive. This adds extra cost to the fuel, leaving little incentive for smaller distributers to add sufficient additive. Aside from the label indicating the type of fuel on the pump, the customer will never be sure as to how much additive is actually in the fuel. Another concern is the Viscosity of ULS fuel; Diesel Fuel Pumps rely on the fuel to lubricate and cool, however after 'Severe Hydro-Treating' many of those properties are greatly reduced. A decreased lubricity will lead to excess wear on pumping elements, delivery valves, injections nozzles, and other metal-to-metal parts that are fuel lubricated. Extra cost, poor lubrication prior to additives, lower viscosity, less B.T.U energy content and major worries of lowered fuel mileage begs the question, why do this?

     The advantages to ULS fuel are: it burns much cleaner, lower emissions, less white-smoke, and faster warm up. The new standards are set to hit retailers Oct. 15 and Sep. 1 in CA. People are asking, "what can be done to prepare my truck?" With a little help, your truck can be running even better than before. The most sensible cost efficient way to safeguard ones truck and promote mileage is to use a 'OEM' Approved Lubricity Additive. Tests have shown that using an additive, such as Stanadyne Performance Formula, will protect your engine and increase fuel mileage. This extra mileage yields a reduction in quantity of fuel needed to be purchased, therefore offsetting the cost of the additive. What this means is you will pay the same amount for fuel, while still getting all the benefits of the lubricity additive.
