The main difference I see is in Ca and Mg. Ones up and ones down just a little. Everything else is very close. Just the change in those two additives could have changed the color. I bet it still works as good as those little elves.
They dropped the Ca levels and increased the Mg. What I find surprising are the levels of P/Zn. Still GF-3 levels. I thought this would have been a GF-4 oil. Probably are not ready to meet the long drains specs and be GF-4. Regardless, with this oil it's the esters that make it shine.
Well I think that this confirms at least a difference in formulation between the amber and the green, if not another reformulation, which means to me that this could be a reformulation of the bases too. So I will not be buying any of the amber stuff, at least without more confirmation and/or other UOA. Heck it was the green color was the only reason I bought it in the first place! Ok, not totally so, but for me it was a novelty purchase and what I saw as a good buy on some confirmed superior Group V and IV oil with superior wear capability. Now it looks just as atractive as the USA made stuff, which I have lots of other options for it seems.
Well I don't know what's in it but I did a microscope exam and the old formula has some strange little semitransparent purple particles. The new formula has some transparent spherical particles. The white ring that shows in the picture is the light from my microscope. If it wasn't for the reflected ring-shaped light you cannot even see them.
I think the purple particles are elf poop but I don't know what the clear objects are?
Yep both say made in Germany. The green color I observed is some light reflecting phenomena and I could not capture it with the camera. It's almost like a fluorescence but different.
Since I've never see GC before before I can't say this is the green others speak of but I'll bet it is.
