As an automotive expert with years of experience in the field, I can tell you that revving the engine can indeed have an impact on your car, but the severity of this impact depends on a variety of factors. Let's delve into the details.
Firstly, it's important to understand what revving an engine means. Revving refers to the act of rapidly increasing the engine's RPM (revolutions per minute) without applying any load to the engine. This is often done by pressing the accelerator pedal while the car is in neutral or with the clutch disengaged.
Now, let's discuss the potential effects of revving:
1. Increased Friction: As you've mentioned, more revolutions can lead to increased friction between the pistons and the cylinder walls. This is because the pistons have to reciprocate more frequently, which can indeed generate more heat and wear over time. However, modern engines are designed to handle a certain amount of stress, and occasional revving is unlikely to cause significant damage.
2. Heat Generation: Revving the engine without load can lead to a rapid increase in temperature. The engine's cooling system is designed to handle the heat generated during normal operation, but when the engine is revved without any load, there is less airflow through the radiator, which can lead to overheating.
3. Engine Wear: Consistent and excessive revving can accelerate the wear of engine components. The engine's bearings, piston rings, and other moving parts can experience increased wear due to the higher RPMs.
4. Oil System Stress: The oil system is responsible for lubricating the engine's moving parts. When you rev the engine, the oil pump has to work harder to maintain adequate pressure and flow, which can put additional stress on the oil system.
5. Valve Train Stress: The valve train, which includes the camshaft, lifters, and valves, can also be subjected to increased stress due to the higher RPMs. This can lead to premature wear or failure of these components.
6. Fuel System Impact: Revving the engine can cause the fuel injectors to operate at a higher frequency, which can potentially lead to issues with the fuel system over time.
7.
Clutch and Transmission: If the clutch is not disengaged while revving, it can lead to increased wear on the clutch and potentially the transmission as well.
However, it's also worth noting that engines are built to be robust and can handle a certain amount of stress. Occasional revving, such as when warming up the engine or during spirited driving, is not likely to cause significant harm. It's the consistent and excessive revving that can lead to problems.
To mitigate the potential negative effects of revving, it's important to:
- Avoid revving the engine excessively or for prolonged periods.
- Ensure the engine is properly warmed up before engaging in high-RPM activities.
- Regularly maintain the engine, including changing the oil and checking for any signs of wear.
- Use high-quality engine oil that meets the manufacturer's specifications.
In conclusion, while revving the engine can have some negative effects, these are generally mitigated by the design and robustness of modern engines. Occasional revving is not likely to cause significant harm, but it's important to be mindful of how you operate your vehicle to ensure the longevity and health of your engine.

Depends on your car, but 99% of the time, yes. More revolutions means the pistons have to reciprocate more frequently, which creates more friction between the pistons and cylinder walls, which doesn't make your engine happy. It's not as bad as you might think though, it just accelerates wear a bit.
