Our DEF Delivery Options
We offer DEF in a range of container sizes to match the scale of your operation, with professional delivery throughout the lower peninsula of Michigan.
Boxes (2.5-gallon)
Convenient for smaller fleets or as a backup supply to top off equipment in the field. Easy to store, handle, and pour with a built-in spout.
Drums (55-gallon)
A practical choice for mid-size operations with regular DEF consumption. Drums are easy to dispense from with standard pump equipment and store cleanly in a shop or yard.
Totes (275- or 330-gallon)
The most economical option for high-volume users. Totes are ideal for large fleets, agricultural operations running multiple pieces of SCR-equipped equipment, or any site where DEF usage is a daily reality. Our drivers deliver totes directly to your location.
In Bulk (Pumped Directly to Your Storage Tank)
For high-volume operations, on-site bulk DEF storage is the most cost-effective way to keep your equipment running. Our Multi-Purpose Lubricant Truck is equipped with on-board DEF storage and a pumping system, delivering DEF directly into your storage tank with a 150-gallon minimum per delivery. In select service areas, we can also broker bulk deliveries through trusted third-party vendors. Bulk delivery means lower per-gallon pricing, no packaging waste, and refills on your schedule. Ideal for trucking fleets, large farms, construction sites, and government or municipal operations.
What Is Diesel Exhaust Fluid?
Diesel exhaust fluid is a non-hazardous, urea-based solution used in Selective Catalytic Reduction (SCR) systems on modern diesel engines. SCR technology reduces harmful nitrogen oxide (NOx) emissions by converting them into harmless nitrogen and water vapor before they leave the exhaust system.
DEF is required by any diesel engine built after 2010 that is equipped with an SCR system, including on-road trucks, heavy equipment, agricultural machinery, and generators. Running low or using off-spec fluid can trigger engine warnings, de-rate your equipment’s power output, or prevent it from starting altogether.
Crystal Flash supplies API-certified, ISO 22241-compliant DEF, so you can be confident every delivery meets the specifications your equipment demands.
Who Uses DEF?
If your operation runs diesel equipment built after 2010, there’s a good chance DEF is already part of your world. Crystal Flash supplies DEF to businesses across a wide range of industries, including:
- Agriculture: Tractors, combines, sprayers, and other modern farm equipment with SCR systems require a consistent DEF supply throughout planting and harvest seasons.
- Construction: Excavators, graders, loaders, and heavy haul trucks all depend on DEF to stay compliant and operational on the job site.
- Transportation & Fleets: Over-the-road trucks, delivery vehicles, and municipal fleets are among the highest-volume DEF users. Reliable bulk delivery keeps your trucks on the road.
- Government & Municipal Services: From public works equipment to school buses, local governments rely on DEF to keep their fleets running cleanly and in compliance with EPA standards.
- Industrial Operations: Generators, mining equipment, and manufacturing facilities with diesel power systems all benefit from a dependable DEF supply partner.
