Best oil for the A-Series

[Vinay-RS]

Deon, thanks for writing this up with your own personal experiences. Abri and I have been chatting about what oil to use and there were a couple of suggestions based on a couple of key issues. One was that the oil needed a high ZDDP content and the other was that viscosity modifiers did not work well with the harsh environment in the gearbox and thinned a lot over time, reducing the efficacy of the oil, suggesting the use of a monograde oil (i.e. SAE 40) instead of the standard 20W50 that is usually recommended.

These were the two articles that were shared with me were:

Another suggestion made by a mini owner who works for an oil company was Fuchs oils. They had a diesel oil that was highly recommended, due to a high ZDDP value and had a similar viscosity. Also unlike some companies they were willing to provide the ZDDP contents of their oils.
