So does anyone have any idea on how these formulation changes may effect the performance of the oil going forward? Do we need to change the acronym for this oil from GC (German Castrol) to BC (Belgian Castrol) since it is now manufactured in Belgium as opposed to Germany?

I have been running the Castrol Edge 0W40 for a few years. I regularly send in samples to Blackstone for analysis. I noticed a significant change in the additive package around my 6/2017 and 11/2017 reports. Boron has increased from around 1-2 up to around 30-50. Calcium has increased from...

Thanks for the posts!

I have a 02'Subaru outback 2.5 EJ25 with a recently installed new short block. Wondering which particular full synthetic Castrol, M1 or Rotella T6 would be best for that engine?

Here's what I run: GC 0w30 in the winter and M1 5w40 TDT in the summer. This car is driven by my wife, who short-trips it to death. I've been going anywhere from 5-8k miles per OCI. Is the GC still readily available here in the US? You want to change out the fluid in the front and rear...
