I noted in my previous post that VW 504.00 oils go through the VW GDI intake-valve-deposit (IVD) test but unfortunately, none of them have LSPI protection or SN PLUS (they have high calcium and no magnesium). There are some great PAO-based oils with low - mid SAPS like Motul 8100 X-clean+ VW 504.00, but they are also expensive, hard to find, and lack LSPI protection.


Thanks. I would stick with M1 EP 5W-30 until something better comes.

Does anyone know if there's a reason why 0W40 cannot be used but 5W40 can be used?

low-mid SAPS ACEA C3 0W40 oils are some of the best stuff for a T-GDI as the low saps will help prevent valve deposits and the 40weight and high HTHS will reduce fuel dilation

So the conclusion is if you want a higher quality oil for a TGDI use one that meets the euro standard MB 229.51, VW 50x.00/50x.00 , BMW LL-04 etc etc

ILSAC is irrelevant

Such questions have been asked on BITOG since it's formation, without a great answer ever coming about.
