Take control of diesel quality: New study reveals huge fuel performance variance across U.S.
"You've got to do something for your own fuel, or accept the consequences of not." --Howes lead chemist Jed Talbot How do you know that what you’re getting from your neighborhood No. 2 diesel pump is quality fuel? The $6-and-more-per-gallon price isn’t going to tell you much, that’s for sure, and chemist Jed Talbot is on a mission to make sure it’s abundantly clear. For this week’s Overdrive Radio podcast, we're dropping in with Talbot and Howes Products marketing lead Rich Guida for plenty detail about a brand-new diesel study showing wide variance in performance characteristics across the United States. Early this year during the winter period, Howes sent three members of the company's long-running trucking-living-legend Hall of Fame out across the country -- Canada, too -- to collect diesel fuel samples straight from the pump: **Trucker-songwriter Tony Justice, well-known for longtime Overdrive Radio listeners: https://overdriveonline.com/15832127 **Owner-operator Kate Whiting, known for her 1970s pristine W900 "Cherry Pie": https://overdriveonline.com/15542803 **"Trucker Josh" Giesbrecht, likewise an owner-operator with a huge Youtube following himself: https://overdriveonline.com/15670149 Back at the lab, Talbot and team then tested each sample for a variety of characteristics -- cloud point and cold filter plugging point, lubricity, biodesel and water content, flash point. Measurements varied widely. Full results via https://howesproducts.com/blog/article/diesel-fuel-test-what-15-diesel-pump-samples-revealed All samples were labeled No. 2 diesel, yet some should have said something different, according to Talbot. One of the samples had a whopping 6% of biodiesel in it, and should have been labeled B5, for instance, and in terms of water content results weren’t much better, with big implications for wear parts in the fuel system. Fuel filters, too. "Water in fuel, particularly in very tight tolerances," said Talbot, is "like molecular sandpaper. It's not good. It's really abrasive, particularly under pressure," also contributing to microbial growt. "So microbes don't grow in diesel. It won't support them. But if you've got a lot of suspended water now you've got a place for microbes to live all fat and happy." What can you do about it? Listen on for ways to establish a baseline with treatments, in use by a majority of owner-operators in Overdrive’s audience year-round, according our research. "When you think about the journey of fuel from the refinery to when you're pulling the handle," Rich Guida said, "it's on railcars. It's stored in places for a little while. Maybe it sits in warm temperature and then gets gets to a cold temperature and then it's in a truck traveling overland. So there's tons of ways water" and other contaminants could be introduced. Various in lubricity measures, too, while none were truly out-of-spec with an HFRR wear scar above the standard, the variation was huge. In that case, the lower the better. Treatment can help reduce that measure, offering potential for extended life for injectors, fuel pumps, cylinder heads all. "So it really boils down to this," Guida said. "It's kind of a crapshoot with what you're getting. And the best way to avoid that is to, to treat consistently and get into a routine."
