Your fuel delivered
Commercial diesel delivery and fleet fueling.
Our own tankers. Our own drivers. Running 24 hours a day, every day of the year — so clear and dyed diesel, gasoline and DEF show up where your equipment already is.
What we carry
Five products. One tanker, one driver, one invoice.
Most sites need more than one fuel. Instead of juggling suppliers, 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.

How the fuel gets to you.
Mobile & fleet fueling
Fleet fueling, wet hosing, wet lining, truck-to-truck fueling — whatever you call it, the tanker comes to the vehicle, the machine or the tank wherever it stands. On call, or on a standing overnight run.
Bulk fuel delivery
Large-volume diesel and gasoline into your own storage, on a schedule or on call.
Emergency response
Power outage, storm, a tank lower than the schedule assumed. Fuel dispatched when something has already gone wrong, with dispatch answering around the clock.
Tank sales & leasing
Short-term rental through to permanent installation, if you need storage on site.
Generator refueling
Standby generators topped up on schedule and refueled through an outage, so the run-time you planned for is the run-time you get.
Rail & locomotive fueling
Fueling at rail yards and industrial rail operations.
Why operators move
It's our truck. It's our driver.
A lot of fuel is brokered — someone sells you the gallons, then goes looking for a carrier to move them. When the schedule slips there is nobody to call who can actually change it.
Summa owns the tankers and employs the drivers. Dispatch is in-house and runs 24/7/365. When something changes on your site at 11pm, the person who answers is the person who can move the truck.

We price it and set the schedule
You get pricing and a delivery window that fits how your site actually works, under a master service agreement.
We deliver, you get the paperwork
Deliveries run to the agreed schedule, with documentation your compliance team can file without chasing us.
