Right, so this a blind study, not "double".
It would be double if the person mailing the sample out to the labs didn't know what oil they were mailing, which would be ridiculous & useless in this experiment. Scientists only use "double" blind methods when the person giving a treatment or drug or conducting the experiment could possibly introduce bias, and in this case, just mailing in a sample doesn't introduce any bias.

Scientists do "double-blind" when the experimenter would have maybe introduced some bias into the experiment. You cannot.

Maybe this study doesn't require such a strenuous level of unbias.
The 3rd party has a secret key. A=Mobil 1, B=PYB, etc. The labs and data cruncher only know A, B, C...

Then you still posted into a Forum that has no relevance to your study.
