## Overview

Over 738,000 fleet locations with diesel-powered commercial vehicles — more than half of all commercial fleet locations in the US. Diesel remains the dominant fuel for medium and heavy-duty operations, creating massive addressable markets for fuel, maintenance, emissions compliance, and eventually electrification services.

## What's Included

- **Diesel Fleet Operators**: Locations with one or more registered diesel vehicles
- **Diesel Count**: Exact number of diesel vehicles per location
- **Full Fuel Profile**: Diesel share alongside gasoline, electric, hybrid, and alternative fuels
- **Fleet Context**: Total fleet size and GVW class breakdown
- **Company Intelligence**: Industry, employee count, revenue, and corporate hierarchy

## Use Cases

### Diesel Fuel Programs
Target the heaviest fuel consumers with fleet fuel cards, bulk diesel purchasing, mobile fueling, and fuel management solutions. Diesel vehicle count directly correlates with fuel spend.

### Parts & Maintenance
Market diesel engine parts, oil and filter programs, transmission service, and preventive maintenance contracts. Diesel vehicles have higher per-unit maintenance costs.

### DEF & Emissions Products
Reach diesel fleet operators with diesel exhaust fluid (DEF), emissions testing, and DPF cleaning services. Regulatory compliance drives recurring demand.

### EV Transition Pipeline
Diesel-heavy fleets represent the largest opportunity for fleet electrification. Identify operators by diesel concentration to build your EV transition pipeline — these accounts have the most to gain from switching.
