How Fuel Quality Impacts Fuel Economy, Engine Performance & Maintenance Costs in Modern Diesel Fleets

Send us Fan MailEpisode 377: In this episode of The Heavy Duty Parts Report, host Jamie Irvine speaks with Jessica Crabtree, Director of Technical Services, and Garth Redifer, Vice President of Sales at Power Service, about how fuel quality directly impacts fuel economy, engine performance, emissions systems, and maintenance costs in modern diesel fleets. They explain how changes in diesel fuel, including ultra-low sulfur diesel, biodiesel, and renewable diesel blends, have increased the importance of managing fuel quality, lubricity, injector cleanliness, and fuel storage practices. The discussion highlights how poor fuel quality can lead to injector deposits, clogged fuel filters, excessive DPF regenerations, reduced fuel economy, increased downtime, and premature wear of fuel system components. The guests emphasize the value of fuel testing, preventive maintenance, proper fuel storage, and the use of quality fuel additives to improve reliability and lower total cost of operation. They also share real-world results showing significant gains in fuel economy and reductions in regeneration events through effective fuel treatment programs.Links·         PowerService.com Sponsors of this EpisodeThe Hub Corp: Introducing the new standard in wheel-end protection: The Hub Corp's revolutionary XTRACTOR™.
