Clean Fuel for the Water

Renewable B20 marine fuel, delivered to the dock

Cape Cod Biofuels supplies B20 ULSD marine fuel, a renewable dyed diesel that blends twenty percent biodiesel with ultra low sulfur diesel. It runs in your boat with no changes, burns cleaner, and is non-toxic and biodegradable, which matters when you work and play on the water.

Because our biodiesel is produced right here from recycled cooking oil, marine fuel is a cost-efficient, homegrown choice for commercial fishing fleets looking to decarbonize, and a cleaner option for every boater on the Cape.

This biofuel saves me money too. The engine does not need as much servicing, and I can be sure it will work because the biofuel is so clean burning. Great, responsive company.

Marine fuel questions, answered

What is B20 marine fuel?

B20 marine fuel is ultra low sulfur diesel blended with twenty percent renewable biodiesel and dyed for marine and off-road use. It burns cleaner than conventional marine diesel, is non-toxic and biodegradable, and runs in your boat with no engine changes.

Which marinas do you deliver to?

We currently deliver dockside at marinas in Sandwich, Barnstable, Harwich, Hyannis, and Mattapoisett, with Falmouth, Onset, and Wareham coming soon. Call us to confirm service at your marina.

Do you fuel commercial and recreational boats?

Yes. We fuel commercial fishing fleets and charter operations as well as recreational boaters. Whether you run a working boat or a weekend cruiser, we can supply clean B20 at the dock.

Will biodiesel affect my marine engine?

No. B20 is a drop-in fuel for standard marine diesel engines. It actually adds lubrication that can help protect your engine, with no performance trade-off.

Is marine fuel cheaper than regular diesel?

Marine fuel is dyed for off-road use, so it is not subject to the highway tax, and because our biodiesel is blended locally it is priced competitively and is not tied to global oil swings.
