At what temperature can waste engine oil be burned?
2 Answers
Waste engine oil can be burned when heated to 200 degrees Celsius. Here is some extended information about engine oil: Methods for disposing of waste engine oil: Waste engine oil can be given to mechanics or sold to oil refineries. Used engine oil should not be discarded carelessly as it can pollute the environment. Both of these methods are very reasonable approaches, whether from the perspective of environmental protection, resource utilization, or economic benefits. Functions of engine oil: Reduces friction and high temperatures: A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby minimizing wear. Sealing function: Engine oil can form a seal between the piston rings and pistons, reducing gas leakage and preventing external contaminants from entering. Anti-rust function: Lubricating oil adheres to the surfaces of parts, protecting them from contact with water, air, acidic substances, and harmful gases.
I'm the kind of person who is particularly sensitive to safety, and I often remind my friends to be cautious when handling used oil. Generally, used oil starts to self-ignite when heated to around 250 to 400 degrees Celsius, with the exact temperature depending on the type of oil and its level of contamination. The flash point may produce smoke above 200 degrees, which can easily cause a fire. This is no trivial matter—never use a stove to burn used oil at home for disposal, or the kitchen will suffer. I recommend taking it to a proper recycling station, where there is professional equipment for safe handling. Recycling not only reduces pollution but also allows the used oil to be repurposed into other products. With safety as the top priority, I've also looked into some cases, such as how oil mixed with impurities is more prone to ignition, so don't take chances. After car repairs, I always clean up oil spills promptly.
