The engine is the part that the rest of the car is built up around.
It is absolutely central to the function of the car. Without it, the car goes nowhere, does not turn on, does not give you air conditioning, or any of that.
It’s a big deal, is what we’re saying.
If you don’t take care of your engine, you’re going to find that your car does not function as well as it could. It will cost you more gas, it won’t go as fast, and eventually it may not take you anywhere at all.
So respect your engine.
