I noticed when I reved my engine a little too hard while in neutral that there is a certain smell that leaks into the cabin. Why does it do that? I am guessing it is probally a bad thing and I am never going to do it again , but can anyone explain what is happening to create that smell?

 

Is your car new??? New engine smell???

 

ive had that same thing. im also curious if this is harming the car

 

Try to avoid revving in neutral alltogether.

It's like shooting a bow with no arrows.

I wouldn't go over like 3500 or 4000 rpm if it's not under load.

 

One more gain?

 

It's bad revving in neutral?

 

yup, it is quite the "BAD" thing to do to a car.
try to avoid it as much as you can.

NOT good to rev an engine to its upper rev range with no load. That smell you observed is probably a normal smell. It's just that when you are moving, the air blows it away.

Mechanically, how is it bad?
