Critical Impact of Fuel Filter Quality on LCV Fleet Operating Costs
- Poor water separation and unfiltered contaminants cause common rail injector blockage and high-pressure pump wear, with a full set of 4 injectors costing over $1,200 to replace, plus vehicle downtime loss of $180–$320 per day per van.
- Clogged low-efficiency filters increase fuel system resistance, raising fuel consumption by 8%–12%, which translates to significant extra fuel cost for fleets with 10+ vehicles.
- Degraded filter media releases fibers into the fuel system, permanently damaging injectors and shortening engine service life by 25%–30%.
