Does this tips work with carburettor engine?

@@safwansyafiq9155 Yes, although it will never be as efficient as a similar engine that has fuel injection.

@@AdvanceDrivingSchool thank you for answering my question

No way will you get over 60mpg in a turbo diesel, even from a small 1.4 turbo diesel. In fact you won't get more than 56mpg in a 1.4 tdi. I had a few diesels including a 1.4 turbo. When I drove at 56mph it returned 56mpg. If I drove at 70mph it returned around 42mpg. Normally aspirated diesels, which no manufacturer makes anymore, would return around 65mpg. You are placing too much faith in your car's onboard computer. They are useful only as a rough guide to fuel usage but are not accurate enough for you to say my car returns 70mpg. The only practical way for the average motorist to calculate accurately fuel economy is to fill up at a service station until the pump cuts out. Reset your tripometer then drive normally until you have used say at least half the tank or better still until your low fuel alarm sounds. Then return to the same pump, fill up again, make a note of the litreage on the pump and record the tripometer reading. You can then calculate your combined fuel return by the most accurate method possible. You cannot look at your computer when it reads 70mpg and say your car returns 70mpg.

@@davidbenjamin5356 i get 70 actual mpg measured by fueling up and distance driven in my skoda octavia 1.6 tdi. You are full of crap and should not make assumptions without knowing anything.

​@@davidbenjamin5356 US mpg vs EU mpg are measured differently by a considerable amount.

We had an ‘05 Impreza STI back in the day ...👌🏼

We always prefer to keep the car in gear, as it gives the driver more control over the cars speed. Safety is more important than saving a little fuel, so we always try to avoid coasting wherever possible. We even made this video about it: kzfaq.info/get/bejne/i7pplpeC3MDIZ5c.html :-)

Staying in the highest gear possible is the middle ground i think, you keep the safety of being in gear, and it has little resistance, although higher than what you would have with neutral. I agree with the 2000 rpm part too, sometimes a little spirited driving open up diesel particulate filters, and is recommended.

​@@magnumopus9058 Highest gear possible without overdoing it. As little gas as possible. High gear but having to push the throttle with no response is a bad sign. But down a hill the hill is in charge of the gears. Steep hills needs engine braking to avoid using brakes. Most hills just requires lifting off the throttle a little. No need to really do anything for most cases. Very common that going from a 60-80km/h zone to say 40km/h I can stick in top gear letting the RPM creep down to just around 1000rpm. Heck even small but long hills in 40km/h zones is it possible to stick it into top gear. The engine braking is so weak that it cancels out the hill at 1100rpm going 40km/h. No fuel used down the hill! But really steep hills at 40km/h might need 3000rpm engine braking to avoid needing to ride brakes down it. But that is kinda extreme one might say. Trying to accelerate in such a high gear at way to low speeds are just bad for the engine and nothing is going to happen speed wise. But keeping the car in gear and not using fuel is eco driving. As is planning how you drive. If going down a hill allows it you should try and burn fuel. At that point your giving the engine the chance of a lifetime to accelerate without burning excessive amount of fuel! Slow at the top and fast at the bottom. Always the case! Unless your to heavy or smart enough to not go to fast down the hill and tip over into the ditch! But really a engine not burning fuel to accelerate is just wasted fuel. And yes the emission stuff and in general clogging of the engine is a real problem when driving like this. Why it never hurts ones in a while to keep up with traffic or just hit 3-4000rpm and get stuff moving. Also looking into the peak torque rpm for the car your in, say 2200rpm being where the engine makes the max torque? Then it really do not hurt much chaining gear at 2300rpm or better yet when going up hills try and shift into that sweet spot and really make it work at peak power where it safely can perform intensely. But peak horsepower for some engines are in the red line range. So stick with peak torque. XD Really going up steep hills you want to be in the peak torque range. Saves on fuel and the engine is going to be allot happier. Better to over rev and land the next gear in max torque range if doing something like accelerating hard or just going up a hill. The temporary extra rpm is far better then trying to force the engine to work hard at to low of a rpm. In a lorry loaded messing the gear shifts up can make the hole vehicle go into a standstill in seconds! Manual shifting a heavy lorries are down right scary as they die right on the spot if you ask it to pull with even a slight to low RPM. No real warning it just loses all power ALL at ones. If you are skilled you can ram a lower gear and save it maybe.

Nice work!

thanks a lot, I just passed the driver's licence and I came here looking for tips. Your answer helped me, in addition to the video ^^ cheers mate

You are not getting that level of fuel economy. The computers are not accurate. Fill up at a pump, reset your tripometer then drive until your tank is nearly empty. Then return to same pump and fill up again. Divide the mileage on your tripometer by the number of litres ( or convert to gallons first ) for the only accurate method of calculating mpg. Then never look at your computer again. Waste of time.

Have you seen this video made with our petrol car? Flexible Gear Selection | Learn to drive: Intermediate skills kzfaq.info/get/bejne/ZrZie9ByqJ3Yh4k.html

Perhaps you have to balance the extra economy of saving weight against the extra distance driven visiting the petrol station more often.

@@AdvanceDrivingSchool not if you are driving past it anyway as I said.

Yes, we have seen some automatic cars have a 'sailing' function where the gearbox disconnects the drive to allow the car to roll (or coast) further. Presumably this must have some benefit to the car's efficiency - but we wouldn't try to copy this in a manual car as it would reduce our control over the car's speed.

On a modern car coasting with the clutch down actually wastes fuel - instead we would use the ‘lift & roll’ technique, as shown in this video: kzfaq.info/get/bejne/o7Vkq8moqbvdcqc.html 👍🏼

Yes, that is the correct size for a U.K. gallon. In both a petrol or diesel car we will save fuel as soon as the engine is stopped - but we are wary of stopping the engine manually too often in case it wears the starter motor prematurely. On a car with ‘start/stop’ built in there will be a heavy duty starting system fitted as standard so it isn’t a problem 👍🏼

Its imposible 😂

If you like!

Its called a ControlPal - we reviewed it here: kzfaq.info/get/bejne/fZiCh9Vims_binU.html

We are actually planning a video on how to maintain the correct road position, so keep a look out!

That would probably depend on the car. Manufacturers are very focussed on getting the absolute best fuel economy possible, so we imagine they would shut down the fuel injection as soon as the throttle is lifted, at any speed. This is because the momentum of the car will keep the engine running, without any need for fuel.

We’re not used to L/km (we use MPG) but if you can match the car’s spec then you are doing well!

There is no need to rev match when eco-driving, as the gear changes should be smooth anyway.

It really depends on the type of engine your car has, and the gear ratios the manufacturer has chosen. In reality we rarely drive in full ‘eco mode’ as we often need extra engine power to accelerate up to speed - so will change gear much later. We made this video to try and explain further: Flexible Gear Selection: kzfaq.info/get/bejne/ZrZie9ByqJ3Yh4k.html 👍🏼

Apart from accelerating gently the biggest way to improve economy is to 'lift and roll' every time you need to slow down for a junction etc. There is so much momentum in the car that it will keep rolling after lifting the accelerator for ages - and this is free travel! If this is done every time before braking you can really improve your figures.

Thank you man,for the tips...appreciate it.

Thanx great advice 👍

3200rpm? That is when you need to up-shift after acceleration. Downshifting to get to 3000+ rpm in a car should be reserved if you need the engine to act as a brake going downhill. And at that point your doing it to avoid riding the brakes down a somewhat steep hill. So your using no fuel and no brake pads to stop acceleration down a hill. Or your about to take off in a lower gear to hit redline for fun! (downshift to speed up fast). There is never really a good reason to go into neutral and coast. Even if modern vehicles do it automatically to save the extra 0.1% fuel. But there most likely is saving to be made talking about a lorry engine pulling 50ton where MAYBE there is a saving in coasting in neutral lowering the RPM by half. Say from 1100rpm to ide 550rpm. Where the gears are so short that even a small change in elevation increase rpm and so also pump losses so fast that you might go into neutral and save fuel. Since it is very likely that a archangel is going to occurs anyways very soon. But even in that environment it is just overdoing it. IF your going down hill your better to get into as high of a gear as possible and lower the engine RPM. But still using the hill to turn the engine over. Advanced driving is going slow at the top of a hill and accelerating down the hill. And before the hill try and have as much energy as possible built up and cress the hill top in a planned way. Maybe there is a hill going down afterwords that you can plan for. At the top of a hill you should be going to slow but still not need to downshift. And at the bottom of a hill you want to brake the speed limit. :c Using the engine as efficiently as possible down the hill and if possible burn fuel at all times. Since slowing down not burning fuel means your wasting what you already burned!

This video might help: How To Avoid Coasting | Learning to drive: Car control skills kzfaq.info/get/bejne/i7pplpeC3MDIZ5c.html

I'm assuming you don't have to come to a stop or otherwise slow down significantly at the bottom of the hill. If your car can maintain speed in neutral going downhill but begins losing speed with your highest gear engaged, then it would be most fuel efficient to coast in neutral. The engine has internal friction drag that increases with rpm. The fuel injectors must continually inject fuel to keep the engine running itself just in order to not create a drag torque on the crankshaft, and probably at an rpm significantly higher than idle at freeway speeds. Therefore more fuel will be burned to keep the engine running and producing zero torque at, say 2000 rpm, than at an idle speed of, say 800 rpm. If your car actually gains speed in neutral going down the hill, then it is still more efficient to leave it in neutral. Placing the car in gear requires fuel to be burned just to maintain speed, and uses the engine very inefficiently at a very light load with maximal valvetrain flow energy loss, and robs the car of energy that could otherwise be built up in the form of increased kinetic energy and used to assist the car on the way up the next hill. However, as a disclaimer, coasting in neutral is not as safe as coasting in gear due to reduction of speed controllability.

We don't use L/Km but I have just done the conversion - you are getting 56mpg urban, and 85mpg on a trip. Those are excellent figures, but please make sure you keep up with the flow of traffic on faster roads. In the UK staying under 50mph on a motorway would frustrate other drivers and could lead to danger. If the road is clear we like to stay above 60mph, even though it does use more fuel.

@@AdvanceDrivingSchool We are campaigning to bring the top speed limit down to 80km/hr on all roads in an effort to cut greenhouse gas emissions and air pollution. The co - benefits are reduced fuel consumption and safer roads.

@Advance Driving School I have found as a driver that it rarely matters what speed you travel at there will always be someone behind getting frustrated. Before keeping to 80km/hr I used to drive at the top speed and very often a driver would sit on my tail flashing because he (generally it was a he, not sure I can recall it ever being a she) wanted to go faster than the limit. These are the dangerous drivers not those keeping to 80 max (or 50mph in your country.) Keeping to 80km/hr, I have in four years, not once experienced someone flashing their lights at me or getting frustrated. If you keep to the left lane there is no problem. I found this to be true in Britain also. Perhaps you could do some experiments yourself and let me know what you experience. In Ireland we got a 43% support, in a national survey, to bring down the top speed limit to 80km/hr to help cut GHG emissions, air pollution and road deaths and injuries.

It’s this: ControlPAL G-force meter | Product Review kzfaq.info/get/bejne/fZiCh9Vims_binU.html 👍🏼

Yes - as long as the car is at the right speed for that gear. Otherwise we would prefer to brake than use the gears to slow down - as brake pads are cheaper to replace than a clutch!

@@AdvanceDrivingSchool Is it OK to upshift directly from 1st to 4th gear?

That would just about be possible if you went as fast as possible in 1st gear - but terrible for fuel economy! This video explains more about missing out gears: Block Gear Changing: kzfaq.info/get/bejne/pa9inrFirtyynpc.html

In an automatic car the most efficient option is to leave it in fully automatic mode, and focus on your driving technique - accelerate gently, reduce hard braking etc. Manually selecting gears will give more control but also use more fuel than staying in Drive.

@@AdvanceDrivingSchool Staying in a higher gear using the manual controls can save fuel, though. Some automatic gearboxes prioritize vehicle responsiveness over fuel efficiency. Also, no automatic gearbox is able to see what's ahead of it. A driver can, and sometimes may be able to be more efficient than the gearbox programming

All the tips in this video will help - but in your car the best fuel economy possible will be far less. Look up the official figures for your car and try to beat those. Good luck!

@@AdvanceDrivingSchool Thanks Just Bought one !!

That depends on which car that engine is fitted to - look up your car’s official fuel economy figures and compare to that 👍🏼

@@AdvanceDrivingSchool wv polo 1.0 tsi. In book it says 5.5l/100km(if I am not wrong) in urban but I think it is impossible because it was tasted in perfect condition. I have so many hills and downhills and lot of other cars.

That depends on the car, and how heavy the traffic is.

You don’t burn fuel but if you lift the pedal and roll in gear the engine brakes you a bit so “your mileage may vary”

Can you answer that?

It’s called a ControlPAL and measures G-forces to help drive more smoothly. We have reviewed it in a separate video 👍🏼

Thanks for the prompt reply!

Another question... lol . what did you use to track your location ie. the blue map that displays with the speed in the bottom left corner . 8:27 . ?

That is a function of the GoPro Hero 5 cameras we use - they record GPS data that can be used to generate the onscreen graphics 👍🏼

or anyone with high prices too.

Most things are the same in either car though - what would you like us to show you in the auto?

is the car wasting fuel when you pull off the accelerator? or it is the same than the manual car?

@@carlos.coronado Try to think of braking as wasting fuel. If you use your accelerator more precisely you won't have 'excess momentum' that needs to be wasted by using the brakes.

This car is a diesel - so has no throttle valve! Perhaps the most efficient technique will vary depending on which type (petrol / diesel / hybrid / electric) of car you are driving - however in our experience we get the best results when accelerating gently.

@@AdvanceDrivingSchool in a diesel its fine to accelerate gently. Im talking petrol cause thats the more common engine in normal cars.

Yes, exactly! I drove badly like that on purpose to show how not to drive!

Advance Driving School but wasn't it supposed to be normal driving just without extra consideration. The people this is aimed at wouldn't stay in 3rd anyway

It`s bad for a diesel engines because of the damage done to dual mass flywheel

When accelerating, keeping the engine revs low is key to good economy - so use enough throttle to keep up with the traffic flow, but change up as early as possible without ‘lugging’ the engine. This works the same in petrol and diesel cars - but the extra torque of a diesel allows earlier up-changes.

@@AdvanceDrivingSchool "extra torque of a diesel allows earlier up-changes" What about damaging dual mass flywheel ? They don`t like very low revs

Of course!

You shouldn't coast in neutral anyway as you have less control and no engine breaking. Coasting in neutral would fail a driving test.

78 mpg on Renault Clio 2013 ;)

100empg on my Tesla

+Shugofa Hamdard Bad luck. Keep learning and you can pass next time hopefully!

Modern cars with automatic gearboxes are clever enough to disconnect and even shut down the engine to actually save fuel when coasting - but in a manual car we could not safely do this ourselves. This link gives more detail: www.pistonheads.com/news/ph-explains/what-is-a-coasting-function-ph-explains/39081

​@@AdvanceDrivingSchool - So first you say it wastes fuel and now you turning it in to safety issues :)

That’s right. We even made this video about it: How To Avoid Coasting | Learn to drive: Car control skills kzfaq.info/get/bejne/i7pplpeC3MDIZ5c.html

Ha ha - so do we sometimes! Have you seen our recent video where we visited a racing circuit?

@@AdvanceDrivingSchool Yes i have indeed... Was that Porsche a company car or one of ur personal ones?

That's our personal car 👍🏼

There is no official curriculum for driving schools, we just do our best to teach new drivers all the skills they need to be a safe driver. On the driving test they do assess the driver for 'Eco-safe skills', but this doesn't affect the test result in any way. Of course, it is up to the individual to decide how they drive after they have passed, and from the low viewing figures for this video (compared to our others of the same age) you can see how few people are interested in improving their eco-driving skills. You might expect that saving 30% of their fuel bill would be an attraction, but I guess not!

The rpm is high because your wheels are rotating and the engine is connected to the tyres. So the tyres turn the engine for FREE. If you put it in neutral, then the engine is idling, which uses fuel. Having low rpm is beneficial only if you're ACCELERATING.

Coasting in neutral uses fuel to keep the engine running.

No - we like to drive on the left 👍🏼

Why is that? Eco-driving doesn't mean driving slowly, so they shouldn't get in your way!

on these b roads you wont save time most of the time even if you drive like a maniac. lets say every 20 miles youll be able to be 2-3 minutes faster thats all.
