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 around 1800 up to around 2300-2500. Magnesium has dropped significantly from around 550 down to 100-200 and recently all the way down to 20-30. Zinc has increased slightly. The wear metals are all still good and low and have not changed much.
I also recently noticed that the 0W40 is now being manufactured in Belgium and not Germany as it has been in the past.
I did a search and did not find any information on the formulation changes or change in country of manufacture. Does anyone have an idea what is going on and any implications as a result of these changes?
