Okay, here's the deal on the automotive nitrous. It Is nitrous oxide years ago when they first started using it. It was just regular nitrous oxide and then people started abusing it, they'd buy a whole tank just to have a big party. I never went to 1 maybe. And what they did was they added a sulfide to the automotive stuff to makes it unpalatable to Huff, that's the whole deal. So yeah, it will make you sick as hell because they added an extra compound to it. But as far as the engines concerned, it just gets burned off. There you go.
