My car won't start, and it's leaking oil.
These issues may be related or they may be completely separate. The most common cause of a no-start is a failed battery. Oil leaks are extremely common and usually caused by failed seals and gaskets. The car also may also not be starting due to low oil pressure / oil levels. Modern cars have a built in failsafe that will protect the engine if the oil level or pressure is to low and not allow the car to start. A qualified Technician like one from YourMechanic will be able to diagnose your car’s starting issue and detect any oil leaks for you. From there, they will be able to make the necessary repairs to get you back on the road.
