From MB to DTFR : Daimler Truck’s new specification system
Daimler Truck AG introduced DTFR — Daimler Truck Fluid Release specifications after the separation of Daimler Truck AG from Mercedes-Benz Group AG. The official Daimler Truck overview states that DTAG had to change its fluid specifications because of the separation, and that the migration was handled in phases, with Phase 2 running from April 2023 to May 2024.
In simple terms: for commercial vehicles / trucks, the old MB sheet numbers are being migrated to DTFR codes. Passenger car and van approvals remain under Mercedes-Benz Group’s MB system, while Daimler Truck uses DTFR for truck operating fluids. Texaco/Chevron also confirms that the new DTFR format came into effect on 1 April 2023, applies to new approvals and renewals, and is specifically for commercial vehicles.
Does it mean new oil chemistry?
Mostly no. For many existing approvals, this is an administrative and naming change, not a formulation change. Texaco states that differences between previous approvals and the new format are administrative/formatting only, with “no technical difference” for the examples shown.
However, this does not mean every DTFR code is only a rename. Daimler Truck’s overview also includes new DTFR categories where there was no old MB equivalent, for example some Actros C axle, transmission, fuel, hydrogen, edAC oil, and other categories.
Key engine oil conversions
For Zeal’s lubricant portfolio, the most important area is likely heavy-duty diesel engine oils. Daimler Truck’s official overview maps the former MB engine oil sheets as follows:| Old MB sheet | New DTFR code | Description |
| MB 228.3 | DTFR 15B110 | Multigrade service engine oils |
| MB 228.5 | DTFR 15B120 | Multigrade service engine oils |
| MB 228.31 | DTFR 15C100 | Low SPAsh multigrade service engine oils |
| MB 228.51 | DTFR 15C110 | Low SPAsh multigrade service engine oils |
| MB 228.52 | DTFR 15C120 | Low SPAsh multigrade service engine oils |
| MB 228.61 | DTFR 15C130 | Low SPAsh multigrade service engine oils |
| MB 228.71 | DTFR 15C140 | Low SPAsh multigrade service engine oils |
Important drivetrain/ fluid categories
Daimler Truck’s DTFR system is broader than engine oil. It covers many operating fluids:| Product area | DTFR family examples | Notes |
| Axle oils | DTFR 12Bxxx / 12Cxxx | Hypoid gear oils, mineral gear oils, Meritor axle oils |
| Transmission oils | DTFR 13Axxx–13Exxx | Manual transmission, ATF, retarder, ZF TraXon |
| Engine oils | DTFR 15Axxx–15Exxx | Service engine oils, Low SAPS engine oils, Cummins X12/X13 Actros C |
| Fuel / DEF | DTFR 16 / 17 | Diesel, hydrogen, AUS 32 / AdBlue |
| Coolants | DTFR 29 | Antifreeze, premix coolants |
| Brake fluids | DTFR 30 | Brake fluid |
| Hydraulic oils | DTFR 31 | Tipper and hydraulic fluids |
| Greases | DTFR 33 | NLGI 00/000, NLGI 2, wheel bearing, drive shaft, complex grease |
| Steering gear oils | DTFR 38 | Commercial vehicle steering/ATF fluids |
What counts as a valid approval?
A key practical point: a DTFR approval is not just a claim printed on a label. A Daimler Truck approval certificate states that the operating fluid is approved for Mercedes-Benz Truck vehicles and assemblies under the relevant DTFR sheet, but the approval is valid only as long as the product name is listed in Mercedes-Benz-Truck BeVo-ONLINE. It also says renewals or new approvals must be made in good time and that other requirements such as SAE grades, capacities, and change intervals must still be observed.
For commercial use, this means Zeal should distinguish between:
“Meets / suitable for DTFR 15C110” — a performance claim, usually based on formulation/additive guidance.
“Approved DTFR 15C110” — should only be used if the product is officially approved and listed by Daimler Truck / BeVo.
Practical impact for Bluenergy Lubricants
Bluenergy’s uploaded company material describes its business as trading and distributing lubricants, greases, base oils, additives, and related petroleum products, including engine oils, hydraulic oils, and gear oils. That makes DTFR relevant for product catalogues, PDS/TDS documents, labels, and customer-facing OEM-spec recommendations.
Recommended action:
- Update product data sheets to show both systems during the market transition, for example:
DTFR 15C110, formerly MB 228.51 - Do not remove legacy MB numbers yet from catalogues, because many mechanics, fleet buyers, and distributors still search by MB 228.xx.
- Verify every “approved” claim against BeVo before printing labels or publishing a PDS. The Daimler Truck certificate language makes listing in BeVo central to validity.
- Segment heavy-duty diesel oils clearly:
- Older / conventional HDDEO: MB 228.3 → DTFR 15B110
- Higher-performance multigrade: MB 228.5 → DTFR 15B120
- Low-SAPS Euro IV/V/VI style products: MB 228.31 / 228.51 / 228.52 → DTFR 15C100 / 15C110 / 15C120
Marketing wording should be conservative unless there is a formal approval certificate. Use “recommended for applications requiring…” only if supported by additive supplier formulation guidance and test coverage; use “approved” only with official listing.
Most commercially important code to focus on
For a modern truck engine oil line, the priority DTFR code is likely:
DTFR 15C110 — formerly MB 228.51
Lubrizol describes DTFR 15C110 as a top-tier low-SAPS lubricant specification for medium- and heavy-duty diesel engines with aftertreatment systems such as DPFs, and notes that it is widely recommended in Daimler Euro VI vehicles.
For Bluenergy’s catalogue, this would typically support positioning for SAE 5W-30, 10W-30, or 10W-40 heavy-duty low-SAPS diesel engine oils, depending on formulation and actual approvals.
