This is driving me nuts.
Castrol has 2 synthetic products: Castrol Edge with "Syntec Power Technology" in a black bottle, and Castrol Edge with "Fluid Strength Technology" in a gold bottle.
The black bottle used to just be called Syntec, and was Castrol's basic synthetic. The gold bottle is 'newer', AND it has a liquid Titanium additive in it to give the oil more film strength. It used to be marketed as an extended-drain oil, but now is not, it is just marketed as Castrol's premium synthetic.
However, brand-new bottles of Edge with Syntec Power Technology are advertising that THEY are fortified with a liquid Titanium additive for additional film strength, just like the Edge with Fluid Strength Technology.
SO, could someone PLEASE explain exactly WHAT the difference is between these two products?? So far, only difference I can see is that the black-bottle stuff is cheaper than the gold-bottled stuff.
I know the gold-bottle Edge is Castrol's premium synthetic product, but it now sounds like it is the exact same as the black-bottle Edge...
Anyone?
