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.

Does high rpm clean engine?

Is revving the engine in neutral bad?

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.

Is it bad to rev a diesel engine?

Poppycock. An idling diesel circulates more than enough lube to keep everything well oiled, and revving the engine then shutting if off can leave unburned fuel in the combustion chambers and even starve the turbocharger bearing, because the turbo will keep spinning after the oil supply dies.

Can a car last 500000 miles?

Today a million miles, or even 500,000 miles, is still extremely unusual for a vehicle. … Consumer Reports, through its annual questionnaire, has found that thousands of people have gone over 200,000 miles in their original vehicles without catastrophic failures or major repairs.
