Will a car explode if it leaks oil?

No, when a car leaks oil, it will not explode as long as there is no open flame or electrical spark. If the oil completely leaks out, it is even less likely to explode. Gasoline has an extremely low ignition point and is highly flammable, so any explosion or fire in a car is usually caused by gasoline. Engine oil has a very high ignition point and is almost completely non-explosive; at most, it can act as an accelerant if the car catches fire. Here are the reasons for car oil leaks: 1. Poor product (component) quality, substandard materials or craftsmanship, or structural design issues. 2. Uneven tightening force of fastening nuts, stripped threads, broken fasteners, or loose and detached parts leading to operational failure. 3. Wear and tear over time on sealing materials, aging, deterioration, or deformation causing failure. 4. Overfilling of lubricating oil, excessively high oil levels, or using the wrong type of oil.
Car oil leakage itself is unlikely to directly cause an explosion, but it poses a serious safety hazard. As someone who frequently drives older cars, I've experienced this firsthand: gasoline leaked onto the exhaust pipe, and the high temperature nearly caused a fire and explosion. The reason is that gasoline is highly volatile, forming combustible gases that can ignite upon contact with sparks; engine oil has a higher ignition point, posing less risk, but accumulation under the engine can also lead to spontaneous combustion. Oil leaks often stem from cracked fuel lines, aging seals, or collision damage. It's advisable to regularly inspect the fuel system and the underside of the engine during maintenance. If you smell fuel, immediately stop the car, turn off the engine, and shut down all electronic devices to prevent sparks—do not attempt to start the engine or perform repairs. It's best to call a tow truck to take the car to a repair shop. Developing a habit of checking for oil stains under the car during daily driving can reduce 90% of the risk. Don’t take it lightly—safety first.
