This analysis was done after 10k miles on the Rotella T6 and 27k miles on the odometer of my GTI. Approximately 1/2qt was added around 8k miles. Car has a stage 1 tune and aftermarket intake.
My driving habits vary quite a bit, so I'll probably just stick to the 10k OCI with the knowledge that I have a little buffer left.
FYI for any other VW folks out there, this oil actually does not hold any VW ratings, but I'm pretty confident it would meet all their requirements if tested.
I wonder if this is an example of the lack of accuracy of blackstone's fuel test. That's a pretty significant viscosity loss to not have any fuel dilution.
