Is it bad to drive slow at low RPMs in 4th or 5th gear?
To answer your question, no it isn’t bad for your car to keep it in as high a gear as you can while still maintaining speed. As long as you are above idle in RPM and your engine isn’t lugging, you aren’t doing any damage. See this link for more information about lugging. You mentioned that you might do this to be quieter and for fuel efficiency.
When does the engine stop rpm dropping below idle speed?
Unless you try something unrealistic (like trying to drive up a 20% gradient in 5th gear at 30 mph) the engine management system stops RPM dropping below idle speed in any case, by increasing the fuel supply.
What happens when you drive in second gear?
Driving in Second Gear at speeds less than 25 mph. Thus, when you apply the gas (as you must do periodically, even when driving slowly on ice or snow), you are much more likely to reduce the traction of those drive wheels, as compared to if you just left your gear selector in the “D” position.
Can you determine the top speed for second gear?
That can determine the top speed for 2nd gear. garrichie July 5, 2016, 7:27pm #4 Automatic – Corolla Joseph_E_Meehan July 5, 2016, 7:27pm #5 Why do you want to drive in second gear? Is it an automatic or manual transmission? What is the RPM at the speeds you are driving? What are the speeds you are driving?
What should the rate of revolutions be on an idling engine?
A properly idling engine should be able to maintain a steady but low rate of revolutions, somewhere in the vicinity of 1,000 RPM. Your tachometer needle should be steady and not jumping around.
Can you drive a car at 25 mph in second gear?
With an automatic this should not be a problem. You can drive your car forever at 25MPH in second gear. I won’t hurt the car or transmission. I assume you understand the situation in regard to control and skidding.

Is it bad to drive in 5th gear?
For example, going 20 mph in 5th gear down a quiet city street that you know has no stop signs for half a mile or more. To answer your question, no it isn’t bad for your car to keep it in as high a gear as you can while still maintaining speed.
Why does my diesel engine hiccup in low gears?
It is not usually a serious issue but is more of a nuisance. Drivers with a DSG tranny in the low gears may have it also, but in that case, it is simply due to the split-second timing between gears. Diesel engines are different than gas engines.

What causes engine hesitation and stumble problems on the 90 +?
Then it developed an intermittent hesitation problem- you would be cruising at 60mph, on a 400 mile trip, ease off the gas pedal, and suddenly for 1/4 second, it was as though someone had switched off the engine and then turned it back on again. The car would then run faultlessly for the rest of the trip.
Why does my Mitsubishi Starion have engine hesitation?
As another example, I still have a 1987 Mitsubishi Starion, which ran perfectly for 35,000 miles. Then it developed an intermittent hesitation problem- you would be cruising at 60mph, on a 400 mile trip, ease off the gas pedal, and suddenly for 1/4 second, it was as though someone had switched off the engine and then turned it back on again.
How does a gear ratio affect the speed of a gear?
The gear ratio tells us how fast one gear is rotating when compared to another. If our input gear (10 teeth) is rotating at 5 rpms , and it is connected to our output gear (50 teeth), our output gear will rotate at 1 rpms. Why?
Why do you drive in a lower gear?
This is due to the lower torque available to the rear wheels. In a lower gear, relative torque is increased and you will gain your higher speed faster with the same (or less) amount of throttle input, which means you can upshift your transmission and get your RPMs down again.
When to use a gearbox to decrease motor speed?
Using a gearbox with a smaller motor enables the unit to operate at lower speeds. In order to understand the importance of using a gearbox to decrease motor speed, consider this scenario. You have a pastry conveyor that adds cherry filling as the pastries go by.
Why is the RPM so high at low speeds?
It is an automatic and shifting is very hard. It doesn’t seem to shift over second gear. It occasionally shifts into third gear within a mile of driving, but after that, it cannot shift over second gear. Also, when this issue starts happening, even though I am driving at very low speeds from 25-35 mph, the RPM increases to around 2800.

How does gear ratio affect speed and torque?
When the rear end gear ratio is 1:1, the amount of speed and torque is similar. Therefore, when you increase the axle ratio, you reduce the amount of torque and significantly increase speed, and if you reduce the axle ratio, you reduce speed and boost the torque.
This is due to the lower torque available to the rear wheels. In a lower gear, relative torque is increased and you will gain your higher speed faster with the same (or less) amount of throttle input, which means you can upshift your transmission and get your RPMs down again.
What kind of car failed in 4th gear?
The other day my ’03 Ford Fiesta suddenly failed in 4th gear when I changed from 3rd to 4th.
What causes revs to go up in high gears?
The most likely cause is a worn or misadjusted clutch. The clutch disc is slipping meaning that all the engine’s power is not being transmitted to the transmission. The cost of a clutch replacement is too varied to give an accurate estimate.
For example, going 20 mph in 5th gear down a quiet city street that you know has no stop signs for half a mile or more. To answer your question, no it isn’t bad for your car to keep it in as high a gear as you can while still maintaining speed.
