Urania LD9 10W-40 CK-4
Synthetic low-SAPS oil for Euro V/VI engines with particulate filters, API CK-4
SAE 10W-40
URANIA LD9 is a low-ash, semi-synthetic SAE 10W-40 heavy-duty engine oil designed for trucks and commercial vehicles with Euro V and Euro VI engines equipped with SCR, EGR and DPF emission-control systems. Its low-ash formulation is compatible with diesel particulate filters and helps preserve after-treatment system efficiency. The oil meets API CJ-4/SM and ACEA E7/E9 and is approved to IVECO Standard 18-1804 Class TLS E9 (Contractual Technical Ref. N° I109.L12) and MB-Approval 228.31. Its performance level also covers CAT ECF-3/ECF-2/ECF-1a, Cummins CES 20081, Detroit Diesel 93K218, Deutz DQC III-10-LA, Mack EO-O Premium Plus-07, MAN M3575, MTU Oil Type 2.1, Renault RVI RLD-3 and Volvo VDS-4, and it is suitable for DAF and Scania engines with DPF at normal oil-change intervals. Typical values: density 0.867 g/cm³ at 15 °C, viscosity 15.5 cSt at 100 °C, viscosity index 155, flash point above 200 °C, pour point below -30 °C and TBN 9.2 mg KOH/g.

ACEA E7 and E9 — heavy-duty diesel, with and without DPF
Two ACEA sequences quoted together: E7 for heavy-duty diesel engines without a particulate filter, E9 for engines with a DPF, where sulphated ash must be capped. An oil meeting both covers a mixed fleet.
Caterpillar ECF-3, ECF-2 and ECF-1a
Caterpillar's three engine crankcase fluid categories quoted together: an oil covering all of them can serve both newer DPF-equipped CAT engines and older ones.
The Cummins specification matching the API CK-4 level, for modern heavy-duty diesel engines with exhaust aftertreatment.
Deutz DQC III-10 LA (low ash)
Deutz class III with the LA — low ash — marking, for engines fitted with a particulate filter or SCR catalyst.
MAN M 3575 — Euro VI engine oil
MAN's engine oil specification for Euro VI trucks, with SCR system protection requirements.
Mercedes-Benz approval 228.31
