The beauty of the various tactics is that they would be easy to recall and perform in a stressful situation. However, a bit of fact-checking would’ve been useful in a few cases, in particular with the flammability of motor oil. In one section, we are instructed to light a quart oil on fire for various reasons, but cold motor oil won’t ignite with a lighter or match. Hoping I was wrong about this, I tried and failed. On cloth, cotton balls, or paper towels, however, motor oil will light and burn well, but when it’s simply poured on the floor or ground, you’re not going to get it to light for love or money. Other than that, I found no problems with the info provided.
