The Fuel Pulse Show

Erik Bjornstad continues the discussion on diagnosing generator problems, focusing on when and how to test fuel before accepting a technician's diagnosis that "bad fuel" is causing your generator failures. The episode covers proper fuel testing procedures, sampling techniques, visual inspection clues, and how to interpret lab results to save potentially thousands in unnecessary fuel replacement costs. Erik emphasizes the value of proper diagnostics and consulting with true fuel experts when generator technicians (who often lack fuel expertise) blame fuel quality for system issues. What You'll Learn: Why generator service technicians often blame fuel for problems when they can't find mechanical issues The specific properties of diesel fuel that can legitimately cause generator problems (flashpoint, cetane rating, viscosity, lubricity) How to properly sample fuel for testing without contaminating the sample Why pulling samples from the "dead bottom" of tanks provides misleading results How to use a "bacon bomb" fuel sampler to get diagnostically functional samples What visual inspection can (and cannot) tell you about fuel quality Why gasoline contamination in diesel is hazardous Which laboratory tests provide the most valuable diagnostic information How to interpret fuel test results to make informed decisions When to consider consulting with a specialized fuel expert Ideas Worth Sharing: Here are three notable quotes from the podcast episode: "Most of the generator service technicians, they know a lot about generators. They do not know that much about fuel. Most of them that conclude that the condition has to be due to a fuel problem, they don't really know enough to say that for sure, to make that diagnosis for sure." "Before you commit to dumping thousands of dollars worth of stored fuel over a technician's hunch like this, you need to take some diagnostic steps to confirm whether the fuel actually is bad and is causing the problems that they think it is." "If all of the tests come back in spec, then that means your fuel's normal. Your fuel meets the minimum requirements in all of the areas that have been determined by the industry to have to do with supporting the minimum operating functions of your engine and your generator and not contributing to component damage."

In this episode of the Fuel Pulse Show, host Erik Bjornstad delves into the basics of long-term diesel fuel storage. He explains that diesel fuel begins to degrade almost immediately after refining due to unstable molecules and environmental factors like heat, oxygen, water, and microbial contamination. Bjornstad discusses various tests to assess fuel health, including water and sediment, oxidative stability, and microbial testing. He recommends removing water and biomass, eliminating microbial contamination, and using fuel stabilizers to slow degradation. The episode emphasizes the importance of early intervention and regular maintenance to extend the life of stored diesel fuel, providing valuable insights for fuel storage management. What You'll Learn: The chemical processes that occur in stored diesel fuel Factors that accelerate fuel degradation during storage How to assess the health and stability of stored fuel Key tests for evaluating fuel condition, including water and sediment, oxidative stability, and microbial tests Methods to slow down fuel degradation and extend storage life The importance of removing water and biomass from stored fuel Why addressing microbial contamination is crucial for fuel stability The role of fuel stabilizers in preserving fuel quality Best practices for maintaining stored diesel fuel over long periods The significance of early intervention in fuel storage management Ideas Worth Sharing: Here are three notable quotes from the podcast episode: "Heat speeds up all of those chemical reactions linked to degrading the fuel. This kind of process always happens faster in hot weather than cold weather." "Using a fuel stabilizer is an essential step to stopping the oxidative and other chemical reactions that, if left unchecked, will result in stored fuel degradation." "Even if you could avoid every single one of these, you would still have reactive precursor molecules already in the fuel that would start to attack healthy fuel molecules virtually from day one."

This episode of the Fuel Pulse Show introduces a "Back to School" series, focusing on the differences between modern Ultra Low Sulfur Diesel (ULSD) and older diesel fuels. Host Eric Bjornstad explains how sulfur content in diesel fuel has been drastically reduced over the past 35 years due to environmental regulations. While this change has improved air quality, it has also led to new challenges in fuel management. ULSD is more prone to water absorption, microbial growth, and instability. It also contains small amounts of biodiesel and has a lower aromatic content. The episode highlights the importance of understanding these changes for proper fuel storage and engine maintenance. What You'll Learn: The history of diesel fuel sulfur content regulations The definition and characteristics of Ultra Low Sulfur Diesel (ULSD) How ULSD differs from older diesel fuels in terms of water absorption The presence of biodiesel in modern diesel fuel and its benefits The impact of lower aromatic content on microbial growth in ULSD Why modern diesel fuel is less stable than its predecessors How ULSD is more susceptible to cold flow gelling in winter Ideas Worth Sharing: Here are three notable quotes from the podcast episode: "In a span of about just 15 years, they reduced sulfur emissions by 99.7 percent from 5,000 down to 15 PPM." "ULSD fuels have bigger water problems than diesel fuels in the past. And it's directly tied to removing the sulfur." "While that has made it much better for the environment, the resulting fuel has more problems than before."

This episode discusses the effects of prolonged hot weather on stored fuel and offers preventative measures. Heat accelerates fuel degradation, increases water buildup, and promotes microbial growth. The host recommends three key steps to combat these issues: 1) Regularly check for water in storage tanks and remove it promptly. 2) Treat fuel with a stabilizer early in summer to slow degradation. 3) Conduct microbial testing, preferably using ATP By Filtration methodology, at the beginning and end of summer. If elevated microbial levels are detected, treat with biocide. These proactive steps can help maintain fuel quality and prevent costly problems in hot weather conditions. What You'll Learn: How prolonged heat exposure affects stored fuel The impact of temperature on fuel evaporation and composition Why hot weather increases water buildup in fuel tanks The connection between heat, water, and microbial growth in fuel Three key strategies to protect fuel during hot weather The advantages of quantifiable microbial testing methods Why ATP by Filtration is recommended for microbial testing How to approach microbial testing if you can't afford specialized equipment The importance of proactive fuel management in hot weather Ideas Worth Sharing: Here are three notable quotes from the podcast episode: "Heat affects fuel by affecting its evaporation, changing the fuel's composition, accelerating fuel instability, increasing water buildup in the fuel, and by making microbial contamination markedly easier to develop." "Microbial contamination is killed by adding biocide to the contaminated fuel. It is not killed, it is not solved, by removing water, contrary to what some in the industry might want to say." "Doing ATP by filtration methodology requires a specialized piece of equipment called the Illuminometer. If we had to name a downside for ATP by filtration, the start-up cost could be a little higher."
