On- and Off-Road Diesel Fuel Delivery in Wells, Maine

Commercial Diesel Fuel Services for Southern Coastal Maine

Diesel fuel plays a critical role in keeping businesses, farms, generators, and fleets running smoothly. Whether you’re operating heavy machinery off the grid or managing a logistics fleet on the road, Garthwaite Energy provides reliable on- and off-road diesel fuel delivery throughout Wells, Maine, and surrounding areas.


As a locally owned provider, we understand the challenges our commercial and agricultural clients face. That’s why we offer timely delivery, competitive pricing, and the responsive customer support you can only get from a hometown partner.

Off-Road Diesel for Generators, Farms, and Construction Equipment

Our off-road diesel—also known as dyed diesel—is ideal for equipment and vehicles not operated on public highways. It’s dyed red per federal and state guidelines and not subject to highway taxes, making it a more cost-effective option for:

  • Backup and standby generators
  • Farm machinery and irrigation pumps
  • Construction equipment (excavators, loaders, etc.)
  • Logging and forestry vehicles
  • Industrial tanks for heating or manufacturing
  • Marine or dock-based fueling applications

We offer flexible delivery scheduling, tank refills, and emergency service—because downtime isn't an option when you're running critical equipment.

Frequently Asked Questions About Diesel Delivery

  • What’s the Difference Between On-Road and Off-Road Diesel?

    Both fuels are essentially the same in terms of performance, but off-road diesel is dyed red and exempt from highway taxes. It’s meant for equipment not driven on public roads (generators, tractors, loaders, etc.), while on-road diesel is clear and taxed for highway use.

  • Can I Store Diesel On-Site?

    Yes, and we can help. We work with clients who store diesel in tanks for generators or fleets. If you need tank installation or are unsure about compliance, we’re happy to advise you.

  • How Often Can You Deliver Fuel?

    We offer recurring scheduled deliveries or on-demand refueling depending on your usage and tank size. Most clients prefer a set schedule to ensure their operations stay uninterrupted.

  • Do You Offer Bulk Pricing?

    Absolutely. We offer volume discounts for commercial and municipal accounts. Call us at (207) 646-6911 to request a custom quote based on your projected monthly or seasonal fuel usage.

  • Is Off-Road Diesel Legal for Use in Vehicles?

    No. Off-road diesel is strictly for non-road use. Driving a vehicle with dyed diesel on public roads can result in hefty fines. Always use clear (on-road) diesel for any road-legal vehicles.
