Industries
A diesel fuel supplier, not a broker.
Summa runs its own tankers with its own drivers across the Northeast. When the schedule is tight or the weather is bad, that is the difference between a delivery and an apology.

The distinction
Most of what calls itself a fuel supplier is a phone number.
A broker takes your order and finds somebody to carry it. That works until the day capacity is short — a storm, a regional outage, a refinery problem — which is precisely the day you needed it to work.
Summa owns the trucks and employs the drivers. Dispatch is staffed around the clock, every day of the year, and the person answering can see where the tankers are. It is a less impressive claim than most of the industry makes and a more useful one.
That matters more the more your operation depends on fuel arriving. If a late delivery costs you a shift, a job or a generator, the supply chain behind your supplier is your problem too.
Who we supply
Industries that cannot wait for fuel.
Job sites and plant
Dyed off-road diesel to excavators, loaders and generators, on sites where the equipment moves and the access changes weekly.
Logistics and trucking fleets
On-site fueling for tractor units and box trucks, so the shift starts full instead of starting at a pump.
Rail and locomotive
Direct-to-locomotive fueling and rail yard supply, on the timings the yard actually runs to.
Airports and ground support
Aviation fuel supply and ground support equipment fueling.
Generators and critical facilities
Hospitals, data centers and transport hubs running on generator power, where a day tank buys hours rather than days.
Government and municipal agencies
Public fleets, works departments and emergency services, with the delivery documentation a public body has to keep.
Marine and port operations
Fuel into port operations and marine equipment, alongside the landside fleet that serves it.
Manufacturing facilities
Bulk supply into on-site storage for plant that runs continuously and cannot stop to refuel.
What we carry
Five products, one schedule.
Most sites need more than one. Instead of running a supplier per fuel, tell us what is on the ground and we build a single delivery schedule around it.
Clear diesel (ULSD)
Ultra-low sulfur diesel for on-highway trucks and any equipment that drives on public roads.
On-roadDyed diesel
Red-dyed off-road diesel for excavators, loaders, generators and equipment that never leaves the site.
Off-roadRenewable diesel
Chemically equivalent to petroleum diesel, with lower lifecycle emissions. Drops into existing engines with no modification.
Lower carbonGasoline
For light vehicles, small plant and any mixed fleet that runs both fuels.
On-roadDEF
Diesel exhaust fluid, delivered alongside your diesel so emissions compliance never stops a truck.
EmissionsCommon questions
Before you call.
What does a diesel fuel supplier actually do?
Buys fuel at wholesale, holds the capacity to move it, and delivers it on a schedule that matches how a customer burns it. The parts that vary between suppliers are whether they own the trucks, whether dispatch is genuinely staffed around the clock, and what happens in a week when supply is tight.
How is a supplier different from a fuel card?
A fuel card is access to other people's pumps; a supplier brings fuel to you. Cards suit fleets that are dispersed and unpredictable. On-site supply suits fleets that return to a yard, because it removes the detour, the queue and the reconciliation.
What area do you cover?
Summa delivers across the Northeast from its base in Clifton, New Jersey, with New Jersey and New York as its densest coverage.
Is there a minimum volume?
It depends more on the shape of the work than the size of it — a single site burning steadily is easier to serve well than the same volume scattered across a state. Tell us what you run and where, and we will tell you honestly whether we are the right supplier for it.
Do you supply fuel and the tank to keep it in?
Yes. On-site storage can be rented, leased or bought outright, and the people sizing the tank are the people who will be filling it.
