Oil Sludging in Diesel and Gasoline Engines More and more OEM engine manufacturers both diesel and gasoline are seeing problems with oil sludge formation and subsequent problems from oil starvation to engine parts. Today engines are operating at much higher internal temperatures and oil is being asked to due more than ever before. There is [...]

Ultra-Low Sulfur Diesel Fuel Cold Weather Information The Ultra-Low Sulfur Diesel (ULSD (S-15)) that we started to receive in mid 2006 has shown some dramatically different cold weather characteristics from the earlier High Sulfur (HSD (S-5000)) and Low Sulfur Fuels (LSD (S-500)). These new characteristics including higher temperature gelling, wax dropout, icing, and difficulty in [...]

Latest update on cold weather problems with ULSD Welcome to February 5th 2007, the first real winter weather with the "new" Ultra Low Sulfur Diesel (ULSD). After being told by refiners and many distributors that ULSD would be the "be all, end all" magic problem solver for all diesel engines, this is what really happened when [...]

Water problems in gasoline containing ethanol Did you know?  In a 10% Ethanol Blend, it takes as little as 18 gallons of water in a 6,000 gallon tanks to cause Phase Separation. In a 2% blend it takes only 3.6 gallons to cause Phase Separation What is "phase separation", and how do I deal with it?  [...]

Asphaltene Production and Re-polymerization in ULSD Fuels Have you seen filters that look like this. There is a difficult new problem with ULSD fuels. Today most ULSD is derived using the process of catalytic cracking. This form of refining uses very high temperatures, high pressures, and chemicals known as catalysts to refine crude oils into [...]
