About Dolek Energy
Dolek Energy — Your Business's Energy Partner, From the First Drop to a Clean Tank
Dolek Energy is a B2B energy company that supplies businesses, institutions and industrial facilities across Israel with everything related to fuel, diesel and oils — under one roof. Diesel and heating-oil supply, generator fuel and backup, tank maintenance, industrial oils, on-site fueling and AdBlue. We are not a one-off vendor selling liters — we are the partner that makes sure your critical systems simply keep running, every day of the year.

Who We Are: An Energy Company Built Around Operational Continuity
Dolek Energy was founded on one simple understanding: a modern business cannot afford to stop. A data center whose generator won't start, a hospital with no backup power, a plant whose tank fuel is contaminated, or a winter institution whose heating system goes silent on the coldest day of the year — none of these are mere inconveniences. They are operational failures with a real price tag. Dolek Energy exists to close exactly that gap.
Over years of experience in fuel supply, tank maintenance and industrial oils, we have built deep professional knowledge and a proven delivery capability with nationwide coverage. Our choice was to unify the entire energy chain of a business into a single service — instead of splitting it between a fuel supplier, a tank-cleaning specialist and a separate oils vendor. The result for you is one accountable supplier, one point of contact, and one consistent service experience for everything that burns, turns and gets filtered on your site.
Why Dolek Is Different: The Full Fuel Lifecycle, From One Supplier
Most of the market splits in two. On one side are the fuel suppliers, focused on delivery and refilling. On the other are the tank-maintenance and oils specialists, focused on cleaning, filtering and polishing. Dolek Energy is among the few that cover the entire fuel lifecycle under one brand: from the first drop of diesel entering the tank, through routine fueling, all the way to tank cleaning, fuel filtering, the certified disposal of sludge and used oils, and the supply of the industrial oils that keep your equipment alive.
For you, the meaning is very practical. Instead of coordinating between several parties — one who supplies diesel, another who cleans the tank, and a third who sells hydraulic oil — you work with a single party that knows your whole system. This shortens response times, prevents finger-pointing between vendors when something goes wrong, and guarantees that the fuel reaching you and the tank holding it are handled to the same standard.
The Principles That Guide Us
Continuity above all
We don't measure ourselves by the liters we sold, but by the downtime we prevented. Supply planning, level monitoring and emergency backup all serve one goal: that your business does not stop.
Standards, not promises
Every product we supply meets the standard relevant to it, with documentation (COA/SDS) on request. Trust in this industry is built on paperwork, not declarations.
Transparency in process and price
Every service has a clear, explained workflow, and every quote is tailored to your volume and frequency — with no surprises on the invoice.
Safety and legal compliance
Working with hazardous materials, certified disposal and regulatory tank testing are an inseparable part of our responsibility — not an add-on.
We Work to the Strictest Standards in the Industry
Reliability in energy is not measured in nice words, but in meeting standards. Dolek Energy operates according to the international and Israeli standards relevant to each product and service, and supplies quality and safety documentation on request — so your maintenance manager gets exactly what the facility file needs:
EN 590 — transport-grade diesel for diesel engines.
SI 701 Part 2 — heating oil / heating diesel.
IEC 60296 — dielectric transformer oil.
API CK-4 — engine oil for heavy vehicles and truck fleets.
DIN 51524-2 / ISO VG — HLP hydraulic oil.
ISO 6743-7 — CNC and metalworking fluids.
Beyond the product standards, we maintain full safety procedures when handling hazardous materials, dispose of old fuels and oils with proper disposal certificates, and perform tightness testing for underground tanks in line with regulatory requirements. Regulatory compliance is not a burden we pass on to you — it is part of the service.
Nationwide Coverage, One Service Desk
Dolek Energy operates nationwide, from central Israel to the north and the south, with one service desk and a single, consistent customer experience. Whether you are a data center in Gush Dan, a hotel in Jerusalem, a plant in the Shfela, an agricultural farm in the north or a construction site in the south — you reach the same team, get the same standard, and speak with people who know your account.
This model lets us serve both single residential buildings and standalone institutions, and large industrial and institutional complexes, at the same level of professionalism. Our main service areas include Gush Dan and Central Israel, the Sharon, Haifa and the north, Jerusalem and its surroundings, the Shfela and the south — with the ability to mobilize quickly even outside our core zones.
When a Critical System Stops — We're Already on the Way
Critical systems leave no room for stoppage, which is why Dolek's emergency desk is available 24/7. A generator that died because of bad fuel, a heating tank that ran dry in the middle of a cold spell, or heavy equipment that stopped on site — all of these demand a fast response, not a "we'll get back to you Monday." We are equipped for urgent supply and fueling nationwide, with special focus on backup systems that must never fall: data centers, hospitals, winter institutions and industrial plants.
An Energy Company That Looks Ahead
We believe energy service for a business should be professional in technology too, not just in trucks. That is why we enable online quote requests, and a unique tool for checking an alternative to an existing product — where you can upload a spec or a photo of a current product (for example an oil drum or a transformer oil) and receive an availability and price check for an equivalent alternative. The goal is to make working with us simple, fast and transparent — exactly how a modern energy supplier should operate.
