That's how I'm interpreting it (not that I'm an expert on fuel by any stretch of the imagination lol). I mean, that's why I find this so intriguing. The idea that you can just pour some of this stuff into your tank and get an immediate 14whp gain -- how can that not catch one's attention? And if I'm understanding the video correctly, they poured it into a tank that already had some regular fuel it, so it was like a 50/50 mix. I'd like to see what would happen if you poured this stuff into an empty tank!
