Do you want to know whether it is safe to drive with overdrive in ON or OFF position? A helpful resource is available in this article.
Let’s talk about supercharger systems in cars, how it works, benefits of supercharger and whether it is acceptable to drive with it ON or OFF.
If it’s okay with you, we’ll begin our discussion immediately.
Driving With OD (OverDrive) ON or OFF
A large number of drivers are aware of supercharging in their cars, but they don’t know much about it.
Consequently, most of them prefer to leave their OD OFF so as not to pose any problem for themselves or the vehicle.
If you have been in that class of drivers, then you need to know when to turn off an overdrive system as well as when to turn it on.
What You Should Learn About Overdrive
Overdrive is a one-of-a-kind transmission system in vehicles that reduces the workload on engines. The system has a lower ratio of 0.6 -0.8 that will allow a car to move at a high speed while reducing RPM.
This means it increases the rotation of your wheel while running in cruise mode.
Consequently, it makes it suitable for driving with the overdrive system on motorways. It also reduces fuel consumption while accelerating and still increases engine performance.
When To ON Overdrive
There may be two reasons why you should activate your overdrive system.
Firstly, you will have to activate your overdrive when you are on a high speed and then if you want to go downgrade.
-
Speeding
Once you drive above 70mph, your RPM will increase dramatically and will make more engine stress, especially in older vehicle models.
At this stage, you are expected to turn on the supercharger to reduce the pressure at which the RPM works. With your overdrive activated, the engine will easily maintain its cruising speed.
What’s more, it reduces fuel consumption and improves the efficiency of your engine as we mentioned earlier. I take it you don’t want to lose your engine because of the pressure.
In addition, you can also activate an overdrive when you want a retrograde, although this is not in every case. So you should keep that in mind.
When To OFF Overdrive
Just like the way you will need to turn on your OD because of certain conditions, certain conditions may guarantee you to turn off your overdrive as well.
Some of these conditions include pulling a major charge, moving to a lower speed, and when there is a flashing light. Let’s have a look at them one by one.
-
Pull a Major Charge
From time to time, you may want to fire major charges on your vehicle like overtaking other vehicles. When you try that, your RPM will increase, and then you’ll start to hear loud sounds from your engine.
At this moment you only need to turn OFF your overdrive system, so that you can change to a lower transmission to saddle up your engine power.
If you don’t, your engine will struggle to fire such a load.
-
Get to Lower Velocity
Of course, you will encounter certain situations that may lead you to switch to lower speeds to avoid powering your motor.
Such circumstances include climbing and descending a hill, bumpy roads, and traffic jams.
Climbing a hill will require you to constantly switch between gears, especially the first two transmissions.
As a result, your engine will continue to run and the RPM will go off whenever there is a downshift to a higher transmission. The same thing will happen when you drive down the hill.
When you get yourself in serious traffic or if you are moving on a rough road, you will also have to keep changing to a lower transmission to maintain the health of your engine.
As such, it is expected that you will deactivate your overdrive.
This is to get you from a higher transmission to a lower one, so the engine will continue to run smoothly and efficiently.
-
Blinking light
Whenever the overdrive light starts to flash, it attempts to alert you to some problems in your transmission system.
This could be an automatic fuel leak, a damaged solenoid valve, or an obstruction in the hydraulic regulator passage.
So you will have to turn your overdrive and carry out a check or better bring it to the mechanic to handle the problem.
The Benefits of the Overdrive System
If you have an overdrive system in your car, there are a few advantages that you can benefit from.
Among these benefits include reduces fuel consumption, less pollution, less noise, increases the durability of the engine, and also makes car parts last longer.
-
Minimizes Fuel Consumption
Are you aware that your engine only uses 1/3 of fuel every time you start your overdrive while driving on the highway?
Thus, an OD reduces fuel consumption while accelerating and in turn, you avoid spending a lot of money on gas.
-
Less Pollution
Similarly, switching on an OD saves approximately 1/3 of the fuel consumption, which reduces the number of emissions from the tailpipe.
By the way, it also has to do with protecting the ozone layer and maintaining a favorable atmosphere.
-
Less Noise
Certainly, you will want to get into a car with less noise so you feel relaxed and more focused.
Powering up a supercharger system will reduce RPM, thereby reducing noise from the engine.
-
Increase Motor Sustainability
Since turning your OD will decrease the amount of pressure on your engine, it will improve its durability.
This is because your overdrive will automatically be switched from high speeds to lower speeds to increase its charge power.
Consequently, it will considerably slow down the aging process.
Thither are a lot more advantages of overdrive; these are just but a few out of many.
However, cars that come with a supercharger system are fairly expensive to obtain, and if it breaks down it is very expensive to perform repairs.
So those are essentially some downsides that you might encounter with overdrive.
Since all we’ve talked about, you should now know when to use and OD.
