I just bought Postal III and played through most of the introduction level. At one point, the Postal Dude has to douse three zombies with gasoline and set them on fire. I took me a long time to get all three zombies because the gas just seems to dribble out of the can and onto the ground around the Postal Dude's feet.
How can I increase the range of the gasoline flow? I'm setting myself on fire more often than enemies.
