Diesel Exhaust Fluid
Keep your equipment running clean
Local Bulk Diesel Exhaust Fluid Delivery for Your Fleet
Diesel Exhaust Fluid delivery from Incredible Oil keeps your trucks and equipment running and within emissions rules. Modern diesel engines need D.E.F. to meet emissions standards, and we keep your supply steady, clean and on time. From construction fleets to trucking operations, we deliver D.E.F. where you need it, in the form that works best for your setup.
Our DEF services include:
- Bulk delivery or packaged totes/jugs
- High-purity D.E.F. that meets ISO standards
- Scheduled deliveries to reduce downtime
- Service for fleets, farms, shops & more
- We offer monitors for auto-delivery customers so that customers don’t run out of product
We take the guesswork out of managing D.E.F. Whether you use it daily or only now and then, we help you avoid costly run-outs with delivery options that fit your operation.
How Diesel Exhaust Fluid delivery works
Tell us how many vehicles or machines you run and roughly how much D.E.F. they use. We then set up a delivery schedule, or we come out when you call. Auto-delivery customers can get a monitor, so we see the level and fill before you run low.
We are based in Wallingford, and we deliver across Central Connecticut. Wallingford is on our route every day. Southington, Berlin, Meriden, Cheshire, Hamden and North Haven are on our Monday, Wednesday and Friday route. Cromwell, Middletown, Middlefield, Durham, North Branford, Branford, Guilford, Madison and Clinton are on our Tuesday and Thursday route.
Many fleets that need Diesel Exhaust Fluid delivery also need fuel. We can bring both on the same stop. See our diesel fuel delivery page, check the towns we serve, or call (203) 265-4328 to get started.

What Our Customers Have To Say
Thank you for the continued amazing service and a special thanks to our driver today that made my 3 year old son’s day by playing peak a boo from our deck while filling and blowing the trucks horn when leaving, you folks are the best!!
John Geary
Impeccable service!! Just had a humidifier added to my HVAC system. I was unable to be home for the install, so I told them how to get in the house. The guys left themselves in, did their job and left the house SPOTLESS. Thanks for being the most trustworthy and the best in the business Incredible Oil.
Keith Sobkowiak
