77 Lubricants Motor Oil VX 0W-30

Worth knowing

VW 504.00 and VW 507.00 are claimed here without carmaker approval, whereas Motor Oil VX 5W-30 from the same line holds official approvals for these codes, plus the API SP class and the MB 229.52 approval. At 100 °C the two hardly differ (12.3 and 12.2 mm²/s) and the sulphated ash is the same, 0.7 %, but they diverge in the cold: CCS 5,800 mPa·s at -35 °C here and 5,940 mPa·s at -30 °C for the 5W-30, pour point -53 °C against -36 °C. So the 5W-30 becomes an option only when that viscosity is in the service book.

On the other hand, BMW Longlife-19 FE is not in the VX 5W-30 entry. The brand has this code only for this oil, and again without approval, while the other oils in the reference that carry it are BMW-approved. The article on BMW approvals places Longlife-19 FE among 0W-30 oils, mostly for diesels. Descriptive words in data sheets should not be compared without figures either: this document calls the oil “LOW SAPS”, while the VX 5W-30 data sheet calls its oil “MID SAPS”, although both are ACEA C3 with 0.7 % ash.
