Just sending away two different HDEO samples for VOA (since I haven't seen these two particular flavors' reports, yet) and noticed a big difference in color/hue of the two oils.
Rotella T6 and Delvac ESP were both a darker amber like the Delo is, haven't seen anything quite as light as the Castrol.
Not sure what, if any, correlation color has with performance/additives/base stock but well, there it is.
I found it interesting, anyways...
