I stand corrected. You're right, pretty much anything will burn under the right conditions. I just read that even antifreeze mixed 50/50 will burn when vaporized by a hot 1000 degree manifold.
"Next tested was automatic transmission fluid. In the early 1990s General Motors experienced numerous fires in its full-sized trucks. Fires usually did not occur in normal usage, but under heavy loads, such as pulling trailers up hills, some transmissions expelled their fluid out onto hot exhaust components and caused fires. As a result, General Motors mailed new dipsticks to owners of these trucks. The new dipsticks had a plastic locking device designed to prevent the internal transmission fluid pressure from ejecting fluid up the dipstick tube and onto the right hand exhaust manifold directly below. Flammability of automatic transmission fluid was demonstrated in the tests by spraying transmission fluid onto the steel tubing, heated to approximately 1,000°F. The transmission fluid immediately flashed."
Sorry we jacked your thread Tony!
