Is it bad to hit the gas while in park?

Nope, no damage was done, except perhaps to the OP’s dignity. Modern vehicles have electronic systems that will not allow you to rev the engine so fast that you will damage it.

Is it good to rev your engine occasionally?

Is it bad to rev your engine in neutral?

No. It may actually be a problem for the drive train. … Many automatic transmission won’t go into gear if the engine speed is too high. So if you rev up the engine in neutral, and shift the transmission into gear, you might just sit there in neutral until the RPMs come down enough for the transmission to engage.

Should you rev in park or neutral?

Answer is….its ok to rev you engine in neutral/park. Just not when its cold and dont hold it on rev limiter! Try not to, because free revving can damage the engine.

Does revving an engine waste gas?

Is it illegal to rev your car?

A person must not start a vehicle, or drive a vehicle, in a way that makes unnecessary noise. This includes unnecessarily revving a vehicle when it is stationary or repeatedly opening and closing the throttle when the vehicle is in motion.

Is it bad to rev a manual car in neutral?

Yes, this causes engine wear. When the transmission is in neutral and the engine is “revved” without any load, the spinning engine internals will accelerate, gathering rotational and lateral forces at a faster rate than designed by the manufacturer. Rapidly revving an engine will heat up the piston rings much faster.

Will revving damage engine?

It helps distribute oil throughout the engine and get the engine block and engine oil up to temperature. Revving the engine won’t speed up the process. In fact, that could cause easily avoided damage. Cold revving causes abrupt temperature changes that create stress between the engine’s tight-fitting components.
