Bleach: car eventually cut out. The bleach also rusted up the gas tank.He might as well buy a box of bleach to flush out all the impurities as well. Pour the bleach in and crank it up for a good 5 min. Drain the bleach, and proceed with the oil change. I believe the mythbusters had an episode on this and the wonders bleach works on a car engine. Much improved gas mileage iirc.

Car caper 7: Bleach in the engine oil
Smoke/steam came pouring out of the engine. The engine got hot enough to set fire to the wood that it was sitting on. To cap it off they fried an egg on the exhaust.
Though there were no spectacular explosions, the engine was pretty well used up.confirmed
