Can 4 Liters of Engine Oil Be Taken on High-Speed Trains?

Carrying engine oil through security check requires obtaining permission from the staff before entering the station. Below is relevant information about engine oil: 1. Introduction: Engine oil, also known as engine lubricant, English name: Engine-oil. It has a density of approximately 0.91kg×10 cubic meters and serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion prevention, as well as shock absorption for the engine. 2. Composition: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties. Additives can compensate for and improve the deficiencies in the base oil's performance, imparting certain new characteristics, making them an important part of lubricating oil.
I've carried engine oil on long-distance trips a few times, but from a safety perspective, absolutely do not bring 4 liters of oil on high-speed trains. Engine oil is a flammable liquid—if it leaks or encounters high temperatures, it could start a fire. With so many passengers onboard, the risk is too great. High-speed train security checks are extremely strict, with liquid items limited to a maximum of 500 milliliters. Your 4 liters far exceed this limit and will definitely be confiscated, possibly even resulting in a fine. I recommend checking the official 12306 website or calling customer service to confirm the policy before taking the risk. While car maintenance is important—engine oil does extend engine life—transportation methods need to be reliable. Consider having someone drive it to you or ordering a new bottle online at your destination to avoid unnecessary hassle. Safety comes first when traveling; prioritize convenience and compliance with regulations to avoid bigger losses over small gains.
