Everything from aftermarket fuel treatments to pump fuel additive packages. Probably a bit old though.

I'm surprised at how long the list is for some companies that make dozens of variations. The big names with lots of different certifications are Chevron Oronite, BASF, and Lubrizol. Infinium has only a few, but I guess those are for XOM and Shell. Sunoco is under their own name. There are also some companies I've never heard of making dozens of different pump fuel additives. And any company marketing ethanol has to register it as an additive with the EPA.
