Don't know. That's the difficult thing about fuel additives. Very rarely does the fuel marketer disclose who makes the additives. Very often they'll even use their own name, even though they don't make the additive in-house. You can assume that Chevron develops their own additives in-house. Shell and Exxon-Mobil have their own additive divisions; actually it's a joint venture called Infineum. Afton is one of the major players in the detergent additive market along with Chevron Oronite, Lubrizol, and BASF.

HiTEC® 6470 is a gasoline performance additive based on Afton’s latest
generation, patented, Mannich detergent technology. HiTEC® 6470 is
formulated to meet the challenges of modern Direct Injection Gasoline
(DIG) technology, whilst continuing to deliver excellent performance in
the traditional Port Fuel Injection (PFI) engine platform.
I'm wondering if the Top Tier or SAE standards will eventually include DI engines for their testing. That could force a change to something different than PEA. I believe the testing engine for Top Tier is one with port injection.
