77 Lubricants Motor Oil CT 5W-40

Worth knowing

Compared with Motor Oil CT 5W-30, this oil has no ACEA C2, MB 229.52 or BMW Longlife-04, claiming BMW Longlife-01 instead; its kinematic viscosity at 100 °C is higher: 13.4 against 12.2 mm²/s. In 5W-40, the brand claims Longlife-04 and MB 229.52 for Motor Oil Synthetic LE 5W-40: it has the same ACEA C3, API SP, MB 229.31 and MB 229.51, with VW 505.00 and VW 505.01 added, but no GM dexos2 or BMW Longlife-01, and the manufacturer marks the MB and BMW approvals as pending confirmation. Motor Oil MP 5W-40 and Motor Oil Synthetic 5W-40 are not class C3: they are ACEA A3/B4 oils with 1.3 % ash.

The data sheet gives the BMW LL-01 claim with the note “<- 2019 BMW LL-01 applications”, that is, only for applications up to 2019. The document gives no sulphated ash figure, although it calls the oil Mid SAPS; instead it gives CCS viscosity at -30 °C: 5,980 mPa·s, whereas the SAE J300 limit for 5W is 6,600 mPa·s. The guide to what oil a BMW needs briefly explains how Longlife-01 differs from Longlife-04 and BMW’s newer designations.
