Can Waste Engine Oil Be Ignited?

Waste engine oil can be ignited. Hazards of Waste Engine Oil: Waste engine oil contains carcinogenic, mutagenic, and teratogenic substances, as well as waste acids, heavy metals, and other harmful materials that pose significant risks to human health. Organic compounds such as aromatic hydrocarbons are particularly toxic, capable of lodging in the lungs and entering the bloodstream to affect the entire body. These substances can interfere with the hematopoietic system, nervous system, etc., leading to blood disorders. Heavy metals like lead and cadmium are difficult to eliminate from the body and severely impact the nervous system. Characteristics of Waste Engine Oil: Waste engine oil refers to used oil that has been replaced from various machinery, vehicles, ships, and equipment due to oxidation, thermal decomposition, and contamination by impurities, rendering its physical and chemical properties unsuitable for continued use. During its service life, lubricating oil accumulates large amounts of sludge and oxides from external contamination, diminishing or completely losing its functions such as friction control, wear reduction, cooling, sealing, and vibration damping. This results in the formation of waste oil—a semi-solid or liquid product composed of wholly or partially used mineral or synthetic hydrocarbons (synthetic oils), residues from storage tanks, mixtures of oil and water, and emulsions.
As a seasoned driver with years of experience, I can confidently say that used motor oil is definitely flammable, but you really need to be careful with it. I remember one time when I tried to burn a barrel of used oil in my backyard to save some trouble, and the flames shot up much faster than I expected, nearly catching the haystack on fire. Thick smoke billowed out, making me cough for ages. Motor oil itself is petroleum-based and combustible like gasoline, but it contains metal particles and additives that release toxic gases like lead and sulfur when burned, causing significant environmental harm. Later, I read online that many community fires are caused by careless burning of used oil, and improper disposal can even be illegal. Now, I collect my used oil and take it to a recycling center—it's safe and eco-friendly, so why take the risk? Remember, safe driving also means safe waste disposal.
