Does it cost more fuel if u are in 1000 spins per min or 3000?

Question

Let's say you are driving is it better to be in 3rd gear and have 3000 spins(you know how much your enigen rolls that meter u see next to your kilo meters per hour) or be in 4th gear and be in 1000 spins per min

sorry for my bad english
why does my word english have a red line?

Let's say you are driving is it better to be in 3rd gear and have 3rpm (revolutions per minute) or be in 4th gear and be in 1rpm

Answer 1

If your talking about RPM's.. Rotations Per Minute.. It takes more gas the higher the RPMS

Answer 2

Hi,

I think by "spins" you mean rpm (revolutions per minute). The meter you are talking about is called the "tachometer".

It is better to keep your revs low. Shifting earlier (<3000 rpm) promotes fuel economy and decreases engine wear at the same time. Shifting late is harder on your wallet both fuel-wise and repair-wise.

You should not be at 1000rpm (unless you have a pretty good car) - around 1000rpm is when the "lugging" begins and the engine revs too slowly. There is too much load on the motor and it is not good for the parts and may cause pre-ignition.

Hope this helps.

Cheers,

The whole point of gears on a car is so you can go faster without the engine having to work hard.
The harder its working (the higher the RPM) the more wear and tear and more fuel it will consume.
As longer as the RPM doesnt drop below the stall point (usually a little less then 1000rpm) then its better to be in the higher gear. So 4th at 1000rpm would be ok but make sure it doesnt stall the engine. To give yourself a little breathing room, try and settle it on 2000rpm. Low engine wear and low fuel consumption, but not likely to stall.

Answer 4

Every engine has a most efficiant RPM to operate at. In many casses lower RPMs will save fuel but at times the cost is the engine. High performance engines designed for high RPMs can have poor efficiency when lugging at low RPM.
Always follow your vehicles recommended shifting instruction and never lug the engine. 900 or 1000 RPMs is OK for idling with no load but is too low for loaded driving.
Driving in a gear too low or too high can be dangerous. You may need the acceleration or control to avoid an accident. The NTSB has reported wrong gear as causing accidents.

Answer 5

It'll definitely cost most of fuel at 3000 rpm(revolutions per minute). Just for the simple fact that spark plugs ignite the fuel. When your distributor rotor is moving fast it sparks fast making you burn more fuel. Now when it comes to wear and tear accelerating fast on a low gear will definitely stress the motor and transmission out, which will indeed break seals in prolonged use, which will end up costing you more money on repairs than on gas. Good luck!!!!!!!!

Answer 6

RPM stands for Revolutions per minute, not rounds per minue... And on the dial in your car the number of RPMs will be in the thousands, ie 2K RPM which is two thousand revs per minute.

The lower the revs RPM the less fuel you use, but if you use more RPMs then your car will go faster and get to your destination sooner. It is recconed that 50mph in fifth gear is the optimal speed for saving fuel. Sometimes you can find this info in your car's information booklet.

Answer 7

It depends on the situation.

If you are driving on level ground, and the car can cope with it easily at 1000rpm in 4th gear, then that will be more efficient than 3000rpm in 4th gear.

However, if your engine is labouring (struggling to hold speed) so that you need to press harder on the accelerator pedal to keep the speed constant (e.g up a hill) then 3rd gear and 3000 rpm might be more efficient.

Answer 8

Yes higher RPM's (rounds per min) burns more fuel.
Theres a few cases where that's not true though. If you have a high performance engine with a bigger cam, bigger heads, larger valves, more compression, etc. All of those mods moves your power band up higher in the RPM.. So by driving that engine at a higher RPM where its making more power, will burn less fuel.

Stock or very mild modded cars aint like that though.. Lower RPMs, better fuel mileage.

Answer 9

the higher the rpm, the more the engine is turning, - the more petrol the engine is using, besides, 3000rpm is very high, this would cost you 3 times more.
dont go half-choking the engine though, you would damage it.
you can go upto around 4500rpm, and about 1300rpm, depending on your car ofcourse. most cars idle at 950 rpm, but this would not be enough power to get up the average hill

Answer 10

you're talking about revs per minute (RPM), and the lower this is then the lower your fuel consumption is.
