The EPA passed regulations to reduce emissions from diesel engines. Manufacturers have released new engines to comply with these regulations. These common rail engines operate at a significantly higher pressure — up to 30,000 psi — and require fuel that meets the ISO 4406 particulate standard. Out of spec fuel can plug vehicle fuel filters, cause filter blowouts, injector damage and can potentially void your warranty.
Tier 4 Diesel Engines
Many industries including trucking, railroads, mining, power generation, back-up power generators and automobiles us diesel engines. New engines operate at a significantly higher pressure. Poor fuel quality causes erosive and abrasive wear in these engines leading to premature component failure and costly downtime. The cost of failure includes repairs to the engine, lost production, unplanned downtime and, in critical diesel applications like back-up generator systems at a hospital, can also endanger lives.
