I'm interested in this additive, but a little confused about the dates involved. Deysha said that the change to XT-11-QDC happened on 8/15/11, but my '12 GT was built on 6/27/11, so it still has whatever fluid came before that. Am I ok adding the XL-18 to it, or do I have to drain and fill with XT-11-QDC first?


2012 GT Premium, 400A, Kona Blue, manual, electronics pkg, 3.73s, Brembos, no spoiler, no stripes.
