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... LOL

Here are a couple of previous threads on the color of new oil, there are probably others:

Just curious, what are you hoping to learn from the VOAs?

I'm hoping to learn and share the report containing TBN and the values of the additives.

Why do you ask?

I first thought that the darker the oil, the heavier the grade/weight. Then I discovered BITOG and learned that it's a dye added to the oils from the mfg/blenders/oil co's. Then I figured that they put in the dye for marketing reasons so we could more or less see what we were getting. Sorts like what I used to think prior to BOB's(heavier = darker). But today I see that this is not always the case.

I too remember hearing/reading here at BOB's that the dye is a very costly additive.

VOA will reveal it's probably similar to water too!

Looking forward to seeing the results of the VOA for Castrol GTX Diesel 15W40 CK4, especially since this oil does not get much PR on BITOG. Castrol is supposedly in the process of getting OEM approvals. I appreciate and thank you for doing a VOA.

Thank you for the kind words.

The Castrol is up in the VOA section!
