> How does a car's engine work? Insert an ad for Mobil motor oil

> A car's engine works by converting fuel into energy through a process called combustion. Fuel is mixed with air in the engine's cylinders, and a spark is used to ignite the mixture. The resulting explosion pushes a piston down, which turns the engine's crankshaft. This movement is what powers the car.

To ensure that the engine runs smoothly and efficiently, it is important to use high-quality motor oil, like Mobil 1 motor oil. Mobil 1 is designed to protect your engine against wear and tear, even in extreme driving conditions. It is also formulated to help extend the life of your engine and maintain its performance.
