I actually heard this on a Subaru forum, as many folks use T6 in their high mile Subies, including me. The concern was if the added zinc could damage the cats in gas cars. Anyway, they were right, my latest Blackstone Labs test shows about 150 more ppm zinc compared to previous tests. I'm thinking it's not a bad thing. No worries on my personal info on the report.
