Hypermiling (Getting unbelievable mileage on Petrol)

[drtanveerali]

@Bilal
Very well elaburated lines. I like ur approach. Keep up the good work.

[hdaackda]

Normally, my vitz giving me an avg of 4 Rs / Km with AC in city. But I noticed, if I dont get my cylinder full.. My average improves a Lot. comes down to around 3. What could be the reason.

Let me explain. If I empty the cylinder, and get it topped up. I do ~100km max with AC (~400Rs)

But If I empty the cylinder and only get gas worth say 200Rs, I can do more than 60km!

Has it got something to do with pressure/volume?

Different gas stations dont matter...

[Morani]

before reading this artical, My santro was giving me 24km/kg Max on CNG (without AC)... after reading this artical, it rose to around 29km/kg on CNG (without AC)...

Awesome!

I'm glad its working out for you guys!

after hypermiling now we have hypersavings in electricity. the idea is to on the fan and then when its starts moving, shut it off, and u will have cool air for about 1 min, do this countinuously as long as u want fan. with a/c on it an then switch it off after 10 mins and then on it again after 10 mins. when u r boiling water, on the stove and then put the stove off and wait for 10 mins before lighting the stove again! seriously what a load of crap is this???? its not like the only thing i have in my life is driving my car. i need to get from point a to b to c to d and to e and then do lots of other stuff in my life. if i go the way u suggest then surely i will save considerable amount of money, but due to continuous tension of switching my engine off and on i will die of heart failure in 5 years. what good will be a few rupees then??? this is such a waste of a thread. drive cars and get on with ur life. we got way too much stuff to think about and take tension about without also having to drive like a nut case just to save a few rupees. i do support sensible driving, and not accelerating like a manic everytime the light goes green but this is taking it to the extreme. sorry if i am offending anyone here, but that is the way it is practically.

what good is it to waste time writing this post? you could have gone to point F aftr point E even

Simple, if u dont like it, dont do it.

Oh and, boiling water like that would take more energy and more cost.. read up on ur science

this is only for us crazy people who like to go to extremes. its fun, its science.

^ and most importantly it saves money.

I get the best mileage when i keep my foot light on the accelerator, specially when driving in city, where if you accelerate Quickly you have to brake Quickly as well.

You sure this is Pakistani Army you have in your signature ? aren't these indians ?

its not at-all good thing to put car in neutral n let it roll down for watif in acase uve to apply brakes????wen car is in gear its in better control of driver cuz he can downshift immediately n this down shift will also work as brakes so car will stop early...hypermiling on cost of accident...NOT WISE!
this cud b done on less or shud i say ABANDONED roads whr no car or human being is too b seen n u can do ur hypermiling..on roads of pakistan whr u can predict wats comin,its dangerous!
the best bet u can do is to acclerate properly n slowl,dont push hard n dont apply brakes like mad!keep tyres properly inflated n keep least amount of load on ur car...
plus as u said BRAKES IN NEUTRAL,tht will wear off the brake pads more early than if u also use DOWN SHIFT technique...thing i just learnt from internet...its good for u if ur doin it but i dont think u shud encourage it to other to do so too!!!

100% sure. read article on NY Times. Verifies the video is real. Also, recently Kiyani ordered the 'investigation' of this video. (of which I am sure nothing would happen)

yar about these videotapes,u knw only half the story ...get to knw the other half n then put them up so openly....i can write much more but this aint the place for it...

@Bilal: I drive an auto tranny and try to do as much of this as possible. I get around 12kmpl with a 1500 cc engine. I wanted to ask what'll be the coasting technique for auto trannys.

Yes, and this brings us to the topic of hyper stupidity.

Why not save your self from pressing the keys on a keyboard and all the electrical signals that pass through the wires of your computer into the CPU.

On a serious thought, yes, it does apply to saving electricity, but not in a moronic way that you have suggested to stand besides a fan and keep shutting it off. Although that too is a very good idea (not yours) if it can be automated. If a switch automatically turns if off for a couple of seconds after any particular amount of revolutions, it would save tons of energy for all of us.

Setting the air conditioner to 26 degrees is one 'Hyper Electricity Saving'. Using energy-saver bulbs instead of the yellow bulbs is another way.

I wonder why you could not think of these very obvious ways to save electricity and went straight ahead to standing besides a fan switch and turning it on and off every once in a while?

drive like a nut case just to save a few rupees.

For a nut-case, I agree, its all about saving a few rupees. But for someone who is intelligent, its not about saving 'a few rupees.' Its about enjoying the ride and saving thousands of rupees and not having to worry about installing a CNG kit in it.

There are many other reasons for Hypermiling. Lowering the dependency on foreign oil is one. "Utilizing" the energy we have is another. The less petrol we import, the more our economy will improve. This is the reason that unlike most of the Pakwheelers, I am not at all against CNG. I am only against the unprofessional and faulty installation of "CNG Kits" which is why I have refused to install this in my car. CNG is one beautiful fuel that we have been given in our country that can run our cars for hundreds of years to come. It reduces our dependency on foreign oil and also is very economic.

Our cars have ABS. Please save your time and use it in writing about something that could help any one. I have applied breaks on my car at 100 as well as at 120 on neutral.

When you're testing ABS, you have to put the car to neutral otherwise its engine would get a good jerk when it turns off as you reach speeds closer to zero.

One other very important point to notice is that you (and by all means I mean whoever acts like what I am about to write) look like a complete moron when you raise a point that has been talked about a dozen times before.

Please just search for "Neutral" in this thread, and then feel a little bit shame, and then write something that was not discussed. Because otherwise, the writer assumes they have written something worth reading, and those who have read it already, think its worth deleting.

Hi,

For automatic transmission you should accelerate by trying to maintain the RPM somewhere at 2000 to 2300. Coasting on an automatic transmission car is just releasing the foot from the accelerator. Although that doesn't seem to be very effective, but its still better than not doing anything at all.

Obviously you cannot shift to neutral with automatic cars, releasing the foot from the gas does the closest thing to it.

Its however really easy to 'accelerate slowly' with automatic cars. Its not that easy with Manual cars because by nature they ask the driver to accelerate quickly. Therefore by making the most use of this particular benefit that you have, you can probably get closer to the average manual cars get.

Remember that coasting is not essentially the most important factor of hypermiling.. The most important thing to keep in mind if you want to Hypermile is to 'maintain the momentum.' Instead of accelerating and decelerating again and again, try to maintain a constant speed.

@bilal

Nice thread, but you forgot to mention a very important point which has great impact on fuel economy and that is tire inflation pressure which can effect your fuel efficiency as much as 25%.

What car you have and how you calculated the averages?Another question what is the lowest rpm on which you can drive your vehicle(i learned that driving below 1500 can damage the engine).

i meant it as a joke, when i said about turning fan on and off. i thought u would get it. and yes this is very very stupid to do what u r propagandizing on this post. and about lowering dependency on foreign oil, well that is inevitable coz of our current government (but let's not get int that). Driving sensibly should be promoted but not taking it to the extreme like u suggest. by the way dont u have anything else to do other than do this hymermiling which by the way wont even work on out roads where u will be going at 40km/h and then a pot hole comes right infront of u and u have to slam on the brakes right away to avoid it. and what will u do when that rikshaw infront of u decides that he needs to take a right turn infront of u? hypermiling is only possible on roads that r not crowded and are not broken. our roads cannot be trusted even at 30km/h speed.

That's what I love about Pakwheels, no matter how stupid you are or something, there is always somebody worst.

1. What you said about turning off the fan etc was irrelevant. I have no where suggested to put the car in neutral every once in a while. Rather what I said was that when acceleration is not required, you can shift to neutral instead of slamming on the breaks right at the point where you want to stop. Most of the people I believe do read the posts, that's why they don't make such obnoxious points.

2. You said its "very very stupid" what I am propagandizing in this thread, here is what I don't understand:

   • Whats very very stupid about driving calmly and safely in a way that saves fuel?
   • Whats very very stupid about driving within speed limits.
   • Whats very very stupid about anticipating road conditions and avoiding surprizes.
   • Whats very very stupid about not slamming on the breaks and not hitting the gas like morons and driving like grown ups?
   • Whats very very stupid about being clever and intellegent?
   • Whats very very intellegent about wasiting money?
   • Whats very very stupid about checking tire pressure regularly?
   • Whats very very stupid about removing useless load from the car?
   • Whats very very stupid about regularly changing the air filter?

Have you lost it? Wait, let me check how old you are.. brb..

Right, so you're 23.. hmm.. I assumed you were 12 or something, really.

What exactly is very very stupid about any of these things, or anything else anyone ever said in this thread... besides your posts?

If our roads have khaddaz this increases the need of hypermiling. How does having khaddaz require someone to drive like maniacs and morons?

I guess I've really made it easy for you to differentiate between very very stupid posts and things that reasonable people, normal people, generally write.

You sir, really need to focus on things that are worth deleting, instead of commenting on things which might be offensive to things, and not humans.

Nowhere have I pointed out a person, place or thing per se and abused it.

I would like to draw your attention to the following pages of this same website, and then request you to kindly do something about them. You being the moderator should really have known these things way before us normal users:

I wanted to post a lot more links, but then I thought there will be people, as you suggested, who are not "POLITE" enough to digest them. Fact of the matter is, we only find that thing impolite which we 'feel like'. This is really a personal attack for a sensitive person like me.. when there are dozens and dozens of things and posts on the site which are far beyond being impolite, why is that I am the one who gets pointed about things that aren't even close to being impolite?
