5th, or 6th gear (if you car has it) are termed as ‘overdrive’ gears. An overdrive gear allows your car to cruise at a high speed while maintaining low engine revolutions. You’ll use 5th or 6th gear for highway cruising at speeds of 60 mph to 70 mph and are ideal gears for best fuel economy.
At what RPM should I shift 6 speed?
Shift into second gear at 3,000 RPM . Lift off the gas pedal, depress the clutch and move the lever straight down to second. Release the clutch once the lever is in the second gear position then continue to accelerate smoothly. Many modern cars have engines that rev quite high and can be shifted at 6,000 or 7,000 RPM.
At what speed should you use 6th gear?
| Gear Speed | 3rd gear Between 20 mph and 30 mph | 4th gear Between 30 mph and 40 mph | 5th gear 40 mph and above | 6th gear 40 mph and above |

Which gear to use at what speed?
| Gear Speed | 1st Gear From 0mph to 5mph | 2nd Gear From 5mph to 15mph | 3rd Gear From 15mph to 30mph | 4th Gear From 30mph to 40mph |

On what rpm should you shift?
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.
Does high rpm hurt engine?
While extremely low rpm and high loads will damage your transmission right away, sustained high rpm may damage it over the long run . High rpm means more wear on the bearings and oil seals, and quicker transmission fluid breakdown.
How Slow Can You Go in 2nd gear?
| Gear Speed | 1st Gear From 0mph to 5mph | 2nd Gear From 5mph to 15mph | 3rd Gear From 15mph to 30mph | 4th Gear From 30mph to 40mph |
|---|
Is it OK to drive in 2nd gear?
It’s a totally fluid coupling, and since there’s no clutch plate to wear down, it doesn’t pose a real risk. Most automatic transmissions have a W (Winter) mode that starts off in second gear to help prevent the tires from spinning on slick pavement. So, for most drivers, starting in second gear is really no issue.
How do you go from 1st to 2nd smoothly?
- Wait for the revs to drop to the appropriate revs to match it for 2nd, or.
- Release the clutch slower by which time the revs have dropped down to the appropriate revs anyways.
What RPM should my car be at 70mph?
Make sure your OD is on, 3000 seems fine for 70. The motor needs to work harder if you go fast.
At what RPM is an engine most efficient?
Generally speaking, the faster the engine speed, the more fuel the engine is using. Between 1,300 and 1,500 RPM is the most fuel-efficient engine speed, or what some would call the “sweet spot.”
How many RPM is too high?
How many RPMs is too high? Typically, engines idle at about 600-800 rpm . Older engines may go up to 1200 rpm or more while warming up. But if the engine is revving up while idling, even after it’s sufficiently warmed up, you might have a problem.
Is it bad to shift at 5000 RPM?
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).
What is a safe RPM range?
For the best fuel efficiency, keep your RPMs between 1,500 and 2,000 RPM when driving at a constant speed.
Does high RPM clean engine?
Modern drivetrains are programmed to keep engine revolutions low in the name of efficiency, and while it’s indisputable that high RPMs burn fuel faster and increase strain on components , it’s actually good for the engine to run through its RPM range on occasion.
What gear should I be in going uphill?
While going uphill, use the D1, D2, or D3 gears to maintain higher RPMs and give your vehicle more climbing power and speed. Note: Most automatic vehicles have at least a D1 and D2 gear, while some models also have a D3 gear.
