La Mancha Negra is a mysterious black substance that has oozed from roads in Caracas, Venezuela, first appearing in 1986. Since the appearance of La Mancha Negra, it has caused multiple car accidents and claimed many lives. Determining the cause of the substance has proven difficult and there are still no definitive explanations, despite almost two decades of study and millions of dollars spent identifying it. One report stated that it "was a mixture of used engine oil and highly corrosive brake fluid" but was not able to ascertain its origin. The most accepted theory is that La Mancha Negra is the result of countless leaky, old cars spraying their fluids over the roadway.
