Filled up today at a local BP. All the pump handles, as well as lots of signage around the station, announced the addition of "Invigorate" to all fuels. I'm assuming it's their answer to Shell's V-Power and Chevron's Techron, but does anyone have any more in-depth insight? Just curious. FWIW, the "new" fuel was the same price as the "uninvigorated" fuel was last week.
