ACEA E4-22
ACEA E4-22 oils are Ultra High Performance Diesel (UHPD) lubricants designed for use in severe duty, long-drain applications. Engines that recommend these types of lubricants are not typically fitted with advanced aftertreatment devices such as diesel particulate filters (DPFs).
The main physical and chemical requirements for ACEA E4-22 are shown below.
| Requirement | Method | Unit | Limit |
| HTHS viscosity | CEC L-36-90 | mPa.s | ≥ 3.5 |
| Sulphated Ash | ASTM D874 | %wt | ≤ 2.0 |
| Phosphorus | ASTM D5185 | %wt | N/A |
| Sulphur | ASTM D5185 | %wt | N/A |
| Evaporation loss (NOACK) | CEC L-40-93 | % | ≤ 13 |
| Total Base Number | ASTM D2896 | mgKOH/g | ≥ 12 |
ACEA E4-22 is typically grouped with a range of other approvals which may vary depending on the viscosity grade. Some examples of approvals that can be targeted in conjunction with E4-22 are Daimler MB-Approval 228.5, MAN 3277, Scania LDF-3, MTU Oil Category 3 and Deutz DQC IV-18.
