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.
What happens when you rev engine in park?
Revving the engine in a car is the simple act of stepping on the gas pedal while it’s still in park. When you do this, it forces your engine to behave in the same way that it would if you were actually driving your vehicle.
Is it good to rev your engine occasionally?
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.
Is it bad to rev your engine in cold weather?
It’s not a good idea to rev a cold engine. A small warm up period is ok. Most importantly, drive gently until the engine is reasonably warm. If you have an Italian exotic, a longer warm up period is appropriate as older Italian exotics have small oiling openings because they are net engineered for cold climates.
Is it bad to press the gas while in park?
4) The accelerator pedal.
On a modern electronically fuel-injected car, absolutely nothing happens at all when you press this while parked. … Pressing the gas pedal releases some of this into the engine. Do it enough times, and the engine will “flood” with gasoline, and will become difficult to start.
Is it bad to accelerate in park?
THIS ISN’T GENERALLY A GOOD IDEA. Revving in general is unnecessary wear on your engine when you are sitting still, and when in motion it is even more likely to damage your car (because you might do it wrong and shift your car back into gear before allowing the rpms to lower or something like that).
Is it bad to hit the rev limiter?
The rev limiter does not hurt your engine, but bouncing the car off the rev limiter continuously is not a good idea either. If you hit the rev limiter before you shift it slows your run and wastes fuel.
Does high rpm clean engine?
Yes, higher engine speed is a part of knocking off the build-up but high air flow and high heat loads assist in the cleaning process as well.
Do high revs damage engines?
The absolute most stress on an engine occurs at high RPMs. The forces acting upon the rotating assembly are exponentially increased with RPM. That also increases the magnification of any oiling inconsistencies (as small as they may be nowadays), which can be deadly to engines.
Is it okay to rev your engine to warm it up?
The short answer: Yes, you can rev your engine to make it warm up faster. One big caveat to that answer is that it is highly recommended you don’t do that. With modern gasoline vehicles, most manufacturers recommend you start the car and immediately start driving.
Does revving warm engine?
Long answer: if you are in a situation where you need to rev your engine to make your AC cooler, you shouldn’t be revving your engine. AC is unaffected. Heat does warm up faster but revving your engine too high when it’s too cold can be harmful.
Do cars last longer in warmer climates?
Yes in the main they will last longer in warm climates . For example a car which has been sent from the UK to California in 1960s will probably still be running but there will be none running in the UK.
