77 Lubricants Motor Oil VX 0W-20

Worth knowing

Before the list of codes for this oil, the data sheet puts a single word, “Exceeds”, and there is no “Approved” row as in the VX 5W-30. In the reference this sets VX 0W-20 apart: every other oil on the VW 508.00 code page is recorded with an official approval. Among 77 Lubricants 0W-20 oils, the codes VW 508.00, VW 509.00, Porsche C20 and Ford WSS-M2C956-A1 are claimed only here, while MLW, VLV, CP and Synthetic 0W-20 cover other requirements, such as MB 229.71, Volvo VCC RBS0-2AE or GM dexos1 Gen 3. So the same 0W-20 mark on the can does not make these oils interchangeable.

The incompatibility note in the data sheet names a specific pair: VW 504.00 and VW 507.00. For engines with that requirement, the VX line has other viscosities, if the service book permits them: Motor Oil VX 5W-30 with official approval, and Motor Oil VX 0W-30, where the same codes are only claimed. The figures show the difference too: 8.3 mm²/s at 100 °C here against 12.2 and 12.3 mm²/s for those two. The engines for which VW 508.00 and VW 509.00 were introduced are named in the article on VAG approvals.
