Hypermiling (Getting unbelievable mileage on Petrol)

[stonedsaint]

btw
My current achievable mileage on city 06 idsi is 14.5-15 km/liter in city with 60% Ac and about 30% drive to peer-sohava.
And
19.5-20 km/liter on highways with 80% Ac at 100-110 km/hr speed with 3 adults on board with 20-25kg luggage in boot.

Sure will update after implementing few techs from this thread.

YES you get an excellent mileage using these tips.got a 30% inc in mileage last winter. Got over 600kms in a tank full in my civic 1.8 auto. V light throttle n gears used to shift under 2000 rpm.route was gt road kharian to isb airport n back twice.speed not exceeding 100.all the time attention was on speedo and rpm. But it was HELL BORING! I use it less as have an alto on cng as a daily runner. Dont plan doing it again in near future! Id rather enjoy the acceleration n drive rather than conc all the time on the rpm. On the contrary apply the principles on alto n its giving a 30% inc in mileage on cng! Good n informative thread. Many thanks

do u knw abt 'laser irridium plugs',some1 said to me that they give better milege,is it pos?

iridiums will always give better milage as compared to an average copper plug

the best i acieved so far from my corolla 1.3 gli is 13.8km/l

very nice thread.worth reading it.....s

If that is in the city, it is very good. If it is on the highway, it should be better by about 25% at least for that car and engine combination.

My 1.3 GLi also gives more than 13 km/l within city. On highway it gave around 16 km/l speed varying between 110 - 120 km/hr.

I think if these things were any good, or even technically possible, the guys building these cars would have added them. For instance 'lighter cam pulleys" are definitely the lightest they could find. Same goes for the rest of the things.

Similarly, using bigger air intakes may pull more air, but its going to add more dirt to it too. The aim of hypermiling is getting better mileage without sacrificing safety of the passenger as well as the car's engine.

haha so u expect such stuff frm our local assemblers who dont even add air bags.

Yet all super cars are equipped wth the above mentioned stuff.Our regular cars lack these things coz of nothing but cost factor.

New City n Civic r equipped wth Iridium spark plugs though NGK Laser Iridium IZFR6K11 frm factory.Yet Khowta cowrolla dont hav those as it will shrink there profit n u havent heard any1 getin figure like city not even near to it so plugs do hav sum role.

Good info. People who have a very cautious mind would definitely follow these guidelines. But as zunny stated above, driving a 1.8l Civic on Motorway, with a permissible limit of 120kmph, it is extremely boring and difficult to remain at 90kmph!!!
I drive moderately in city, and drive enjoyably on Motorway! My average on Civic Oriel M/T 2009 is 9 in City and 11 on Motorway. And I am happy with it!

i followed the tips and i got 16 km on highway on my gli and 14 in city

You can't say "don't even add air bags" as if Air bags are toffees. Installation of Air Bags costs a lot, which is why they cannot put it in cars running in Pakistan. Its not a matter of choice, its a matter of price. Pakistani Honda City costs us around 13,000 USD. The same car in Australlia is sold for 22,500 and 24,500 in two flavors. How can we say local assemblers "don't even put air bags?" We can't say that.

But in spite of the the awfully reduced price they have still managed to give us a car which is comfortable, has ABS and gives brilliant fuel mileage.

Broh does the 1.8L Civic show petrol mileage like the new City/GLi or do you calculate that manually?

[AmmarFaiz]

i used to hypermile on my way back from uni in Pakistan i'd drive on reserve from H-12 all the way to bahria town and still have gas left over!! (this was on a 2.0L diesel turbo LC) all u have to do is go up to like 50 kmph then put it in neutral and let it coast until its like 20 then slowly accelerate again etc. etc. downhill just put it on neutral as long as its not too steep

You can get 18 on highway easily. Maintain the speed at 100.

Every 5 kilometers you go above 85, you reduce your average by 1.5^2 Km/L.

Yes, this electronically calculated mileage is believable because its too low. As soon as someone gets better mileage, they become unbelievable. Its not the 'electronic calculators' that make it unbelievable, its the number, the higher the difficult, right?

[Bang]

Put 100ml of pure acetone in your tank it will improve by a bunch.

I accept your impeccable intellectualism as a renowned world famous world record holder who can obviously extract fuel economy that eludes even the stupid engineers who designed and built the machine. You, sir, are truly blessed in this regard and I must stop any further conversation on this topic with you immediately.

Actually, running the car on pure acetone will give you about 565 mpg (over 1176.3 mpg if you are the world champion), and will make you independent of mere mortals who are dependent on mere petrol.

I read this reply on my phone and assumed it was posed by "Bang" - the guy above your post - who could have felt himself left out in the discussion and jumped in as a complete moron who has no bloody clue whatsoever of whats being discussed, but I was amazed it wasn't him.

must stop any further conversation on this topic

Before anything else, we must understand that this^^ kind of behavior is generally a result of feeling shameless and trying to drag one's self out of a discussion in a way that sounds very intelligent and save one's self from a lot more humiliation that one can foresee.

Since I answered this same question twice to you, and I remember telling you that you must have read that part, because you are supposed to be moderating all the posts/videos here. Sadly, you turn out to be the one who apparently reads the least. And even though something is answered over and over, dozens of times, you appear to be the one deprived of all the wisdom being shared here and end up making a obnoxious statements that would leave everyone smiling, if not laughing.

Like I said, if you saw Wayne Gerdes's videos, you would have realized that the average he gets is twice of what Honda promises. 21.5 Kilometers per liter in 2.4L Accord.

This is on the record. It was broad casted on CNN. There is no bloody reason not to believe that. Its not impossible.

If a 2.4L car can get 21 KPL, then you have to wonder whats too confounding about a 1.3L car getting 26?

Its a matter of having some brain cells that work. Really. Its not that difficult as much as we end up assuming.

You have no reason, whatsoever, to believe that no engineer on Honda can never do this only because they don't promise this average. The reason is that the average 'promised' by a company is based on how most people would drive a car. Its not based on exceptions. Its based on averages. They would not expect everyone to hypermile because most people, as you suggested, would find it bloody impossible to believe.
