What happens when you rev your car to high rev range?
Your engine will be most efficient and use the least amount of gas while at idle. So anytime you rev your engine to the high rev range you will be using more gas than you would if you let your engine idle.
What makes an engine rev high or low?
One of the simplest ways of creating a high revving engine is to start with an oversquare design (larger bore than stroke). There are multiple advantages of this type of design, but as far as engine RPM is concerned it keeps the piston speed relatively low.
Why does my car Rev high in the morning?
In the past, it wouldn’t rev high. But now, the revs wont go back to normal unless you spend a good 10-15 minutes in park until it “warms up”, even though this also occurs in the summer.

What happens if you rev your engine before warming up?
If you rev your engine before it’s been warmed up the oil may not be able to properly lubricate the engine which means more wear and tear on the internals. In general, the more wear on the internals of an engine the shorter the life of that engine, but revving the engine in your car is fine as long as it’s been properly warmed up.
What does it mean when your engine revs up?
If your engine revs up as you press down on the accelerator but your vehicle doesn’t accelerate as per usual or as you would expect, it’s a troublesome sign that can lead to a full-blown transmission failure. Transmission slipping, or gears slipping, is one of the most common transmission problems on both manual and automatic transmissions.
When does the car over revs and jerks?

Why does my car over Rev when I’m driving?
Hi There, What you are describing may be a result of a faulty speed sensor, potentially low transmission fluid or a even a faulty transmission control solenoid. As your vehicle travels down the road, the computer analyzes data being sent by vehicle speed sensors and engine speed sensors.
When do you start the car, the engine revs?
