I have honda civic and according to the manaul, it says i will get around 40 miles per gallon. I have found some information in a magazine and it helps me to save money on my petrol. I am now getting around 40 mile in town and around 46 to 48 mpg on highways. I will share the information.
Driving smoothly and anticipating the road ahead could save you petrol. Anticipating Driving means if you see red light ahead, there is no point accelerating and apply brake harshly. If you see stop signs such as red light or school patrol, slow down your car as soon as possible (safely) to avoid applying brake at higher speeds.
Accelerating slowly could also save petrol. Harsh accelerating will cost you more.
Even shutting all the windows will make your car could save your petrol.
Driving with the highest gear possible in manual cars and using economy mode in automatic cars would save your petrol.
Use air conditioner only if necessary.
IF YOU FIND ANY MORE METHODS to save petrol, please share here with me and others. Because petrol prices are increasing dramatically over last few years.
put original size tires - bigger tires, biger power needed to move
dont listen music load - it also use petrols for battery recharge
I thought that bigger tires meant that the same anount of power would make the car go farther.
The bigger the tire the large the circumference of the tire. Of course there is a point i suppose that would be right. I wouldnot of course want to put three foor tires om my mid size car.
I have started driving more slowly now, I stick to 60 on the motorway and save quite a bit of petrol compared to if your dong 80.
I also like to accelerate more gently now but every now and then its fun to put your foot down

No, the same amount of rotations will make the car go further, but the larger size makes a higher gear ratio, making the engine work harder for each rotation. This effect would balance out, except for the fact that your car was designed for a certain size tire, and the gear ratios are set to be optimum for that tire size. Basicly, with loversize tires, your city milage will go down, but your highway milage will go up. It'll also have a harder time accelerating (the main reason for effeciency loss) and towing heavy loads. The flipside is, however, that it raises your maximum speed.
As a side note, changing your tire size will make your spedometer innacurate.Not only is it taking more power to drive the car due to a larger tire, there's also more resistance due to a larger "footprint" (the part of the tire actually contacting the road)... trust me in the long run you lose MPGs.
A couple other factors to keep in mind regarding MPG -
1> Tire pressure.. low tires eat up fuel big time
2> Wheel alignment.. being out of alignment meant the tire is literally dragging across the pavement... less fuel economy (and more tire wear)
3> Driving habits.. Anticipate the road ahead and slow it down a little.. you'll notice GREAT improvement by doing this
4> State of tune... a proper running engine gets better MPG than a poor running one
5> Wind resistance... in slow speeds you get better mileage A/C off, windows down, but at HIGH speeds, such as continuous highway driving, you actually get better economy windows up, A/C ON.
6> Weight... hauling 200 lbs of junk in your trunk does make a difference... yes maybe not much, but every little bit helps
7> Fuel type... Ethanol has less power output per unit than gasoline. Here in the US it's now mandatory to make unleaded fuel mixed with 10% ethanol. My truck is a flex-fuel, meaning it can run on fuel that contains as much as 85% alcohol. Using E10 (90% gas/10% alcohol) I get about 20-22MPG. Using E85 (85% alcohol/15% gas) I get about 16-18, BUT it tends to be about $.20 cheaper per gallon.. and supports local farmers instead of middle east oil guys. ALSO use the lowest grade fuel your car can without it pinging.
Hope this helps some guys out!
the petrol here cost you 49.43 per letre that's a peso coz im here in the philippines.
Not to have a 5.7 V8 Firebird in London! 90p per gallon (just under $4!) 10mpg can really hurt!
inflate your tyres to 40PSI will save you even more,
try fill up half tank each time, because fuel is heavy.
Use thinner motor oil like 0w-20 0W-30 in order to reduce
internal drag.
You know what? If you warm up your engine every time you want to start your journey, it will save your fuel. Especially in the morning where your engine is still so cold. I know this method save my fuel.
Well if you work Commuting really helps.
No speeding and fast acceleration is good. making sure you engine is warmed up before you go is good also. And the method that they use for MPG on car stickers are not realistic anyway. I think they changed the requirement now and they manufacturers will have to put real world numbers there.
There's also, of course, an optimal speed to drive in order to conserve fuel. I've read that it generally falls around 90km/h (55mph). I'm sure that depends on the car and probably is the point where you are in your highest gear but still at low revolutions.

40 psi is too high, IMO. I'd stick with the manufacturer's recommendations. Otherwise you might wear your tires wrong and will also lose emergency handling.You have to drive not more than 30 miles/hours. Also avoid breaking and go instantly.

Each vehicle has a different speed at which it gets the best fuel mileage. The fact that the engine uses gas while idling moves this ideal speed up, while the fact that going faster creates exponentially more wind resistance brings the ideal speed down. Therefore, a car that had an engine that used a lot of fuel while idling, but was very aerodynamic would have a high ideal speed, while a car that had an engine that used very little gas at idle speed, but had bad aerodynamics would have a low ideal speed. If you're lucky enough to have a real-time miles-per-gallon readout in your car, you can find what this ideal speed is. Without that, good luck.
