At what RPM is an engine most efficient?
about 1000 rpmIt is likely to be geared for 2500 rpm or so at that speed, yet for maximum efficiency the engine should be running at about 1000 rpm to generate that power as efficiently as possible for that engine (although the actual figures will vary by engine and vehicle)..
What happens if you shift from 5th gear to 1st?
It would depend at what speed you were driving and gear ratios but to put it simply probably you could seriously over rev the engine and destroy it, as well as breaking traction on the driving wheels which on rear traction vehicles would provoke a spin.
What are the 1 2 3 gears in an automatic?
In most automatics, you’ll actually get as much or more power to the wheels in 1,2 or 3 than you will in D. Those selections just limit the transmission to the lower gears. They rarely start off in that gear, so power is the same if you are below the usual shift point, and greater if you are above it, never less.
Does 6th gear save fuel?
6th turning at 1500RPM is the more economical as long as it’s on the flat or decline. If going up hill then use 5th gear to save engine stress and use more torgue.
Can you go from 2nd gear to 4th?
Yes it is recommended that in a modern manual transmission you can skip gears when going up or down. … Alternatively when approaching a corner you may change from 4th or 5th down to 2nd without using the gears in between. Care needs to be exhibited to ensure you have the right speed for the gear.
Is shifting at high RPMs bad?
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. Engines are usually more efficient at lower RPM as well. So early shifting etc will increase your gas milage.

At what RPM should you shift gears?
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 speed should you use 6th gear?
The highest gears in both types of cars are generally reserved for cruising at higher speeds—when you’re on the motorway, for instance. The benefit of a 6th gear is that the vehicle can often feel more comfortable when travelling at 70mph than those limited to 5 forward gears.
Can you go from 3rd gear to 1st?
You can shift to any gear you want, provided you’re at the correct speed range to do so.
What RPM should I start with first gear?
1500 RPMYou’ll want to start giving it gas before you start lifting off of the clutch pedal, so that when the clutch starts grabbing, it won’t immediately stall. Don’t focus so much on the RPMs as much as just feeling out how much throttle is ‘just enough’ (though, generally 1500 RPM is enough; it’s where I put mine at).
