Can engine oil be stored in the trunk during summer?

[Hubert]

Engine oil can be stored in the trunk during summer, and there is no problem as long as it is well sealed. Engine oil is not classified as a hazardous material, nor is it flammable, so it can be safely stored in the trunk. It does not need to comply with the regulations for transporting or storing hazardous materials. Below is additional information: Engine oil, also known as engine lubricant, serves the following main functions: 1. Lubrication and friction reduction: It forms an oil film between two sliding parts, preventing friction and ensuring smooth operation. 2. Auxiliary cooling: When the engine runs, it generates high temperatures. The oil absorbs heat from the operating parts and carries it away, aiding in heat dissipation. 3. Cleaning: It carries away carbon deposits, sludge, and metal wear particles from engine components through circulation, cleaning the working surfaces of the parts as the oil flows.
