Diesel Differences-Whats in Your Tank?
Episode 240
Sunday, 27 September, 2026

Do you really know what you're pumping into your fuel tank? The sign says diesel, but that doesn't mean the fuel coming out of every pump is the same. Refiners must meet certain standards, including cetane rating and sulfur content. But other characteristics that can have a real impact on a truck's operation — including cloud point, cold filter plugging point and suspended water — can vary considerably. Howes Products recently tested diesel fuel samples collected at locations across the U.S. and Canada and found some significant differences. In this episode, Howes chemist Jed Talbot explains what those variations mean, how they can affect fuel-system performance and reliability, and why the diesel you buy in one place may behave very differently from the fuel you buy somewhere else. Full disclosure: Howes Products is a sponsor of this podcast. This episode is not a paid promotion for Howes Products; the discussion focuses on the company's fuel-testing results and what they may mean for truck operators.
