# Question: Is A 3000 RPM Cruise Bad?

## How many RPMs should I shift at?

Generally, you should shift gears up when the tachometer is around “3” or 3,000 RPMs; shift down when the tachometer is around “1” or 1,000 RPMs.

After some experience with driving a stick shift, you’ll be able to figure out when to shift by the way your engine sounds and “feels.” More on that below..

## What should my rpm be at 50 mph?

1500 rpms for 50 mph sounds about right.

## What should your rpm be at 60 mph?

“it does between 2,000 and 2,100 rpm at 60 mph. Then at 70 mph, it’s doing close to 2,500 prm.

## Is 3000 rpm too much?

Running an engine some 3000 RPM below its redline should be absolutely find for extended periods of time. It might “sound” a bit revvy if you run the engine at that RPM when stationary – and indeed it might get hot quite quickly as it will not have the cooling airflow that occurs when driving.

## Is it bad to cruise at 4000 rpm?

It shouldn’t be too bad. But to say that it doesn’t matter is stupid. 4K rpms for hours on end will do some wear on the motor. … rpm’s stay high for longer than normal (like if he knew he was going to downshift or slow down, he’d just hold the revs higher).

## How many RPM is normal?

For the best fuel efficiency, keep your RPMs between 1,500 and 2,000 RPM when driving at a constant speed.

## How fast is 3000 rpm in mph?

Thus, at 6800 rpm one is going 1 mile per minute, or 60 mph, approximately. So, 3000 rpm would be about 26 mph. As a rough approximation, add 2 zeroes to the mph to get rpm: 93 mph is about 9300 rpm.

## How many RPMs is 75 mph?

A fairly common highway cruising speed is 75 MPH. At this speed, in sixth gear, my MINI, and a lot of other cars, turns at 3000 RPM. My MINI’s non-turbo engine delivers good torque at 2000 – 2500 RPM.

## What should my RPMs be at idle?

For a passenger car engine, idle speed is customarily between 600 and 1000 rpm. For medium and heavy duty trucks, it is approximately 600 rpm. For many single-cylinder motorcycle engines, idle speed is set between 1200 and 1500 rpm.

## Is it bad to go high RPMs?

Don’t worry about revving up to 4k rpm, but there is no need to make it a habit. … High RPM get much worse nearing max RPM. Max RPM is the limit that the engine can take before severe damage. Running at or near max RPM for extended periods will drastically reduce engine life.

## Do high revs damage engines?

Your engine is most at risk from damage when cold, so putting undue stress on it by high revving will exponentially increase the damage done. The combustion process does not become efficient until the engine reaches its operating temperature.

## Why is my rpm so high?

If your car has high RPM while idling, it can be attributed to a problem with the idle control valve. This valve helps the car to maintain a specific RPM while idling. This idle control valve also has a fuse which if blown, will stop the valve from working altogether.

## What RPM is dangerous?

If you drive at 5,000 RPM, that bearing is going to use up its lifetime twice as fast as if you were driving at 2,500 RPM. On the other hand, “lugging” an engine at too low an RPM can be harmful, as well. If your prime directive is mechanical lifetime, shoot for lower RPM within a reasonable range (i.e. not lugging).

## How many RPMs should a car be at 70 mph?

2550 RPMA genuine 70 mph is 2550 RPM and over long distances (recently did 430 miles in the day (all on Motorways and fast A roads) is very relaxing.

## What should RPMs be at 80 mph?

Anything close to 2400 rpm at 80 mph in 6th gear would be great.
