2013 Golf TDI- Mobil 1 ESP- Great results!

[DerekG]

This is the 2nd UOA for my Golf. The first one was done with the dealer Castrol Pro and for my first non-free oil change I wanted to try Mobil 1 ESP. I initially planned to change it at 7k for a more apples to apples comparison with the Castrol, but I went on a 3k mile road trip and it was too early to change before the trip so I decided to run over. I'm happy with the results after 9k+ miles on this OCI.

I wonder if the dpf delete would have anything to do with it....in theory there is now less resistance and maybe the engine isn't having to work as hard all else being equal?

I refilled with the 507 Pentosin to compare.

Looks like the ESP is a much better oil for your engine.

How large an oil sump?

I think mobil one ESP is an excellent oil- but I believe the diesel particulate filter and EGR delete definitely lead to less stress on the engine on the oil.

This is the virgin analysis of Mobil 1 ESP per Russian site.

The previous oil lacked both Moly and Boron, so I'm not surprised that the ESP produced better results.
Does anyone know what the Potassium based additive used in the previous oil was, as I've not seen that before ??

The good figures are not due to deleting the EGR or DPF, as there was no fuel contamination present. I'm not a fan of deleting emissions control gear, as it's an anti social act, particularly if the vehicle is used in built up areas. Poor emisions standards are one of the main causes of cancer.
