77 Lubricants Engine Oil Synthetic UHPD 5W-30

Worth knowing

One letter in the name separates this oil from Engine Oil Synthetic EHPD 5W-30, and the typical figures hardly tell them apart: 12.1 and 12 mm²/s at 100 °C, viscosity index 162 in both. Where they part is ash and codes. Sulphated ash is 0.98 % here against 1.5 %, ACEA E8, E11 and API CK-4 are found in this pair only on UHPD, while EHPD has API CI-4 and DTFR 15B120, where the letter B, according to the article on DTFR, MAN and Iveco codes, means an oil for machines without a particulate filter.

The approvals cover MAN M 3677 and Scania LDF-4, but Deutz DQC IV-18 LA and MTU Oil Category 3.1 are only stated as met here. These two codes are listed as approvals for Engine Oil Special UHPD 10W-40, that is, in a different viscosity grade; Scania Low Ash is there too, not here. The data sheet’s “Exceeds” block also contains the word IVECO with no number. Iveco writes the class into the name of its standard 18-1804 (“TLS E6”, “TLS E9”), and the whole name counts, so such an entry does not confirm the requirement from the owner’s manual.
