I've never been one to tinker with air rifles, but this is something that I sort of stumbled upon after getting oil in the wrong spot. At first I was perplexed, and slightly terrified to touch my rifle. I did a little bit more research (Google is remarkably unhelpful when you have no idea what you're trying to find) and found out, this has been known for generations, and countless kids have toyed with it in the past.

That's all good and well for them, but when my air rifle spat smoke and a report louder than I .22 I damn near crapped myself. Perhaps like me you have never heard of this, and if so I encourage you to watch my bumbling and albeit camera shy journey to understand, and put into practice this "Dieseling" phenomenon.

I have an outstanding understanding (haha) of how this all works now, it's amazing what you can learn in a day. So sit back, relax, and spend the next 8 minutes watching me uncover the mystery of the small Oil Mist explosion within my old beat up Air Rifle.

Apparently, I say, "Okay, so..." a bit much. I don't get in front of a camera too often, I'll have to fix that!
