Should you be in Drive or Overdrive when driving on the highway?

In almost all cases a vehicle's transmission should be in Overdrive, or the Top Gear when driving on the highway. This gear selection achieves the best fuel economy with the lowest wear-and-tear on the Vehicle. The possible exception case where it's preferable to use the Drive position is when climbing steeper grades or where the engine needs higher revolutions-per-minute (RPM) to climb a hill or accelerate. Most modern Automatic Transmissions can be safely driven in Overdrive 100% of the time.
An overdrive transmission setting is typically any gear ratio lower than 1.00:1 where the transmissions output shaft rotation speed matches the engine speed. A common overdrive gear ratio would be between 0.85:1 to 0.54:1 meaning the engine runs slower RPM-wise or that the vehicle travels further per engine revolution.

Should you drive your car in drive or overdrive?
If it has overdrive use it! it is a "highway gear" it will make no difference what so ever until you get up to speed then it will shift into overdrive and save you gas!
Can you drive a truck with no overdrive on a highway the overdrive has to be looked at it is about an hour of driving on the highway?
Certainly. It's been done for years before overdrive became a thing... it just means you'll turn higher RPMs at speed, and you'll want to drive slower if you're conscious about fuel consumption. I had no problems when I took my 87 Silverado with a Muncie 465 direct drive transmission on the highway.
Will it hurt your 2001 ram 1500 to be driven in 2 high on the high way?
2 high, is 2 wheel drive which is where you should be when driving on the highway.2 high, is 2 wheel drive which is where you should be when driving on the highway.
Should you drive 97 ford mustang with overdrive on or off?
Overdrive is the normally allowed position , but it won't shift into overdrive until the speed is faster such as on the highway / freeway
What is over drive used for?
Basically highway driving over 45 MPH when minimal power is needed Overdrive - hi-speed/low power
Over drive or normal drive on a mercury sable?
Overdrive is the normally allowed position . It won't shift into overdrive until the speed is higher anyway , such as on the highway / freeway
What is over drive for the ford exporer?
Overdrive is an extra gear assembly in the transmission that allows the engine to run at a lower speed (lower RPM) when you are travelling at higher speeds on the highway or freeway. For example, if I am driving my 1995 Explorer at 62 mph in drive, the engine runs at 2800 RPM. If I am driving at 62 MPH in overdrive, the engine runs around 2100 RPM.
Should you drive with or without overdrive?
If you are driving for a period of time over 45 mph then use overdrive. If you are driving under 45 mph or in traffic that is speeding up and slowing down over and under 45 mph then do not use.
When driving on the highway for a long period of time. what lane should you drive on?
The inside lane, so merging traffic doesn't interfere with your driving.
Is it better to drive with over drive on or off on the rain?
Overdrive use depends on speed, not weather. Can you drive at overdrive speeds, use overdrive. If you can't, don't. Often it's sensible to reduce speed in poor driving conditions.
Should you drive with your over drive on or off on the rain?
The overdrive doesn't care if it's raining or not, all it cares about is the speed. If you're driving fast enough for the overdrive to work, then you should use the overdrive, regardless of weather. If you isn't, you shouldn't, regardless of weather. Often it's sensible to lower speeds in poor weather conditions.
Is it dangerous when the OD off light is on?
Cars with automatic transmissions can sometimes have an overdrive lockout mode, hence the OD light. Most often overdrive is left on for normal day to day driving. Overdrive can be locked out while driving through mills or over a mountain pass and gives the driver better engine performance by eliminating the use of the overdrive gear. If the light is on, overdrive is locked out which will cause the engine to run at a higher rpm rate at highway speeds. If you drive for long period of time at highway speeds the engine may overheat or have a catastrophic failure. Also keep in mind, if the engine is working harder so is the transmission! If the lockout switch or button is malfunctioning and you can't turn the overdrive back on, it should be checked out by your mechanic.
