The history of Joe Gibbs oil (now known as Driven) was Joe Gibbs Racing and several other teams were having issues with the Nascar "sponsor" oil eating cams during break in on the dyno - hence one of his engine builders had the break in oil made to their specifications – As I have been told they had to run the sponsor oil during racing - I would suspect a lot of oil bottles got emptied and filled with their own mix after the break in was done.
