What Diesel Direct does

Diesel Direct, LLC is the largest dedicated mobile on-site fuel delivery company in the United States, providing 24/7 diesel fuel, gasoline, and Diesel Exhaust Fluid (DEF) delivery directly to truck fleets, construction equipment, generators, marine vessels, and other fuel-intensive assets across all 50 states. Founded in 1998 by Dan Abrams and headquartered in Stoughton, Massachusetts, the company operates a custom-built fleet of delivery trucks supported by 300+ supply points and a multi-branch network, eliminating customer trips to retail fuel stations. Its product portfolio spans core on-site fleet fueling, DEF Direct, bulk and off-road fuel delivery, reefer and generator fueling, marine fueling, and emergency fuel management programs.

The company has built a proprietary technology stack around three pillars: FUELLOC (a registered IoT-based fuel management ecosystem that captures real-time dispensing data from trucks and on-site tanks to a cloud platform), BARLOC (a patent-pending barcode system that authorizes only approved vehicles to receive fuel and instantly records transactions), and the Fuel Intelligence Customer Experience Portal (a cloud-based reporting system providing per-gallon visibility, automated invoicing, and consumption analytics). These technologies, developed over more than a decade, underpin a data-driven fuel management offering that differentiates the company from smaller regional mobile fuelers.

Diesel Direct generates revenue primarily through usage-based fuel delivery (gallons delivered at fixed or daily spot pricing), supplemented by subscription-like fuel management technology services, transactional sales of specialty fuel products and additives (Renewable Diesel, Bioheat, RoadChamp, Winter'z Edge), and tiered emergency fuel management programs (Silver/Gold/Platinum). It serves a diversified customer base spanning trucking, construction, food and beverage, energy and utilities, marine, airports, agriculture, rail, waste management, and events, with named engagements including Amazon Air, National Grid, and the Red Cross. The company also operates a Partner Program that extends FUELLOC technology to external parties.

Direct peers

• Sun Coast Resources: Regional mobile fleet fueling and bulk fuel distributor serving commercial and industrial customers across the U.S. Southeast and beyond with on-site diesel and DEF delivery — directly comparable to Diesel Direct's core mobile fueling and DEF Direct offering.
• Quarles Petroleum: Mid-Atlantic mobile fleet fueling and bulk petroleum distributor serving commercial and government accounts with on-site diesel delivery and tank monitoring — closely comparable in service mix, customer segments, and delivery model.
• Shipley Energy: Pennsylvania-based fuel provider offering commercial mobile fleet fueling, bulk delivery, and heating fuels to fleets and businesses — directly comparable in on-site mobile-fueling model and customer types.
• Mansfield Energy: One of the largest U.S. providers of mobile on-site fleet fueling and bulk fuel delivery, with a comparable direct-to-customer model serving commercial fleets, construction, and industrial accounts — making it the closest head-to-head competitor to Diesel Direct in mobile fleet fueling.
• Petroleum Service Group (PSG): Mobile on-site fleet fueling, fuel management, and tank monitoring services for commercial customers — closely comparable technology and service stack (on-site fueling + fuel management software).

Regional players

• RaceTrac: Large U.S. retail fuel chain concentrated in the Southeast offering diesel and fleet programs at forecourt locations — comparable fleet fueling capability but distributed regionally and at retail sites rather than via nationwide mobile delivery.

Broad incumbents

• Love's Travel Stops: Nationwide truck stop and fleet fueling network providing diesel, DEF, and fleet card services — overlapping customer base (over-the-road trucking fleets) but serving them at retail forecourts rather than via on-site delivery.
• Pilot Travel Centers (Pilot Flying J): Largest U.S. truck stop network offering diesel and DEF fueling plus fleet cards at fixed locations — competes with Diesel Direct for the same truck fleet wallet share but through retail-center rather than on-site mobile delivery.

Emerging players

• Booster Fuels: Tech-enabled mobile on-demand fuel delivery for fleets, vehicles, and equipment using an app-based ordering model — overlapping on the mobile-fueling value proposition but with a digital-first GTM that contrasts with Diesel Direct's enterprise field-sales motion.

Others

• WEX Inc. Fleet card and payment infrastructure provider whose fleet cards (e.g., Comdata — which Diesel Direct already accepts) sit adjacent to Diesel Direct's delivery service, with overlap in commercial fleet relationships but no direct fueling logistics.
