DTFR 15C140

DTFR 15C140 (MB 228.71) is a Top Tier low SAPS¹ lubricant specification designed for use in high performance heavy-duty diesel engines where advanced aftertreatment systems such as Diesel Particulate Filters (DPFs) are fitted. With a HTHS viscosity of 2.6-<2.9cP, these lubricants are designed to provide enhanced fuel economy benefits to the latest Daimler OM471 Euro VI engines.

DTFR 15C140 (MB 228.71) lubricants are SAE xW-20 (2.6-<2.9cP) viscosity grade, typically based on API Group III base oil.

The main physical and chemical requirements for DTFR 15C140 are shown below:

Requirement	Method	Unit	Limit
HTHS viscosity at 150°C	CEC L-36-A-90	cP	≥ 2.6 and ≤ 2.9
Sulphated Ash	ASTM D874	%wt	≤ 1.0
Phosphorus	ASTM D5185	%wt	≤ 0.12
Sulfur	ASTM D5185	%wt	≤ 0.4
Evaporation loss (NOACK) at 250°C	CEC L-40-93	%	≤ 13
Total Base Number	ASTM D2896	mgKOH/g	≥ 7.0

Note 1: SAPS refers to Sulphated Ash, Phosphorus and Sulfur, the levels of which are often restricted in the latest performance specifications.

DTFR 15C140 (MB 228.71) approvals that may be found claimed in conjunction with MB 228.71 are Scania LDF-5 and MAN M 3977.
