[QUOTE=Xist;672131]Is it a scam if nobody benefits from it? So, here is their questionable video.
Maybe people who know what they are saying can guide this conversation:
That video isn't the best made by Donut. It's very general, and of course designed for a very general audience. I think they messed up when they mentioned Top Tier fuel and then go on to talk about octane as if they were the same thing. Still, over all I like the video.
