Mr FFK there is no I too know in his request to know the engine size. Agreed, the post doesn't talk about engine size because it is generalises measuring consumption regardless of engine size. Whether you drive a 4,6,8 or 12 cylinder engine, this method helps you measure your fuel consumption. However dextrovert asked about specific vehicles which have varying engine sizes. The toyota corolla for example comes in 1.6, 1.8, 2.0 and 2.4 litre engine and that even depends on the year in question...I think there are some year models will even less engine capacity. This will be the same for the Honda or Peugeot. These different engine sizes and models will have varied consumption. So you see that you are actually the ignorant one and probably that's why you perceive the poster as being an i-too-know. ... what do I know anyway...

Kennydoc:


Perfect response to him. I was pissed when I read his attack on the guy.

As a very economical guy, I always do this every time I fill my tank. Because I'm too sensitive about minimising my fuel consumption, I rarely use my AC. Too bad. Despite the whole economy, I rarely get beyond 22-24mpg (both city and highway) with my 2003 Corolla-S. It's very annoying cos initially, I was thinking I could be getting up to 28-30mpg. I guess the age of the engine is a factor in the low values.

FemiFaniKayode:


Young man you are too pompous where in that formula did you see model and engine size?

Proffesor i too know!

dammytosh:
I don't need to calculate My machine shows that by default.

auhanson:


Age of engine not withstanding , if you clean up things around your air intake; your combustion chambers;your air filter; your cylinder heads(clean up all the carbon buildups over the years); use the recommended set of plugs and make sure your current is not leaking between your plug wires and coil etc you could gain your 28-30mpg or even more. Just try it and your will never let it go, it will remain your regular maintenance tips.

moyinoluwabun:
OP na stingy man. Who get time to dey calculate how much fuel consumed or calculating mpg. Asakasa

obailala:
The mpg figures your car generates are not as accurate as you think.

The method by the Op is the most accurate way to measure your average mpg.

dammytosh:


You don't know what i drive and i don't want to mention it here but trust me, I bought fuel several times and tracked it and can tell you that it is 100% accurate.

obailala:
Yeah but for most cars, it's not exactly as accurate as running the calcs yourself manually.

Even two cars with exact specifications and year of manufacture can still have different fuel consumption rates. Health of the engines could be responsible for this. So, is best each car owner should carry out this exercise on their cars

dammytosh:


Yea I agree with you but my machine is a beast.

It monitors everything 'monitorable' including telling me when one of my tire pressure reduces by 1 unit, oil life and what else have you and it is 100% very accurate.

Siena:


Your opinion. At least you know less about automotive issues than I do, going by your response.

The poster asked for the mpg of 3 cars, with no indication of engine size. The Honda and Peugeot are makes. How can anyone give an answer if there is no indication of brand? Honda could be a 1.3L Jazz or a 3.5L Accord. Will both cars have the same mpg?

It pays to think, before responding to issues you have no knowledge of.

Young man indeed! An assumption that makes you come across as a patronising git.

Siena:


Bro, most cars these days display fuel consumption data, mine do as well. But...they are far from accurate. They give fuel consumption data that MAY be achievable in 100% optimum operating conditions - no gradients, headwinds, traffic, tyres that have very little friction to create drag etc.

Even the indicated fuel range is very difficult to achieve. Fill up your tank, and the range may show 500 miles with a 55 litre tank. I can guarantee you're unlikely to achieve that magical figure.

It's impossible to have all those factors, just as it is impossible to have 100% fuel combustion. Maybe in another 500 years, but for now, no.

The calculated method as shown by the thread starter remains the MOST reliable method of knowing what mpg any vehicle is capable of.

donpata:
Rubbish!! so long as the fuel indicator is not digital, it's a waste of time. By the way, are there cars with digital fuel indicators?

Hey am. too busy to be brickbating with you this sweet beautiful morning, very appalling how people grab on to imaginary holds in the air to make a point.

Let us assume and give you a big BENEFIT OF DOUBT that i know nothing about automobiles and that you know evetything about automobiles.

Since you are a designer, programmer and an acclaimed auto engineer now tell me the formula you will apply while inputining your model and size ish parameters.

Experts have given that formular and it is a scientific fact based on data so if the formular has been simplified enough for end users (despite complications used to arrive to that) and generally applicable to be used on all vehicles

You asking for those parameters makes no damn sense.

ok i drive a Toyota Prius Hybrid 2015 1.8 Engine now calculate my mpg without running to google to check factory acclaimed mpg.

Your questions were dumb and untimely.
Am too busy i know you sleep and drink here I wont respond to you anymore or your likes metioning me

dammytosh:


Mine is accurate !!

I have tested it several times under different circumstances, traffic, no traffic (may be travelling ) etc and in all this occasion, it is accurate.

My car tells me how many hours i have been running my engine which i reset after every full tank.

So don't argue with me on this.

Siena:


This is a forum, and debates are what fora are created for. If you don't wish to encounter "my likes", why did you subscribe to Nairaland? Would you rather this was a forum where everyone shared the same view? Let me burst your bubble, it's not happening.

You don't seem to get it. I can NOT calculate your mpg in your Prius HSD, because I'm not driving it! No one can use the calculation method UNLESS they are driving the car. Calculations are performed by the user, who would have cleared the trip meter to zero when the tank was filled. Calculations do NOT depend upon engine size, they depend on fuel quantity in the tank, elapsed mileage once tank is empty. Simple!

Engine size comes into play when a request is made to tell a subscriber what their manufacturer's mpg values are.

Why is this so difficult to grasp?

And just so you know, I am contracted to Toyota GB as a diagnostic technician. So, I know more about your 2015 Toyota Prius HSD than you think.

You run a 2015 Prius, great. Care to share the basics of your car? We might learn a thing or 2.

FemiFaniKayode:


this is not a political debate so relax it is common sense you did not need to ask him for size and all that bull crap.

All Mr Toyota diagnostic technician needed to do was give him the formula to calculate by himself just in case the poster was blind or something..

How will the engine size you asked or the model help him solve the query?

DEXTROVERT:
Can u help us with normal values of MPG for cars

Toyota corolla
Honda
Peugeot

Siena:


I am relaxed, you're the one who's getting unduly defensive here. The poster himself didn't lose his rag. Why are you over reacting?

This is what the guy posted:



Dex asked for "normal mpg values". Not calculated ones. There was no need to give him any formula to calculate his mpg, as his query was a general one, he is comparing mpg between 3 different cars. The engine sizes would NOT help HIM, but they would help anyone else who may wish to give him manufacturer's mpg figures.

FemiFaniKayode:

My point you asked for parameters that are not part of the simplified equation! i just gave you my model and engine size calculate my mpg you are dancing shakitibobo up and down.

[size=15pt]YOU DID NOT NEED TO ASK HIM THOSE SHIKENA![/size]

Siena:


How did you compare the indicated mpg with calculated values? I'd love to hear this.

Your car must be immune to changes in road gradient, atmospheric temperature, elevation and wind resistance, or the conditions under which you drive are always 100% the same.

Awesome car!

FemiFaniKayode:


Beautiful!!!!! "normal" in his context is ambiguous and probably refers to two things either looking for a general flat mpg value across board for cars or trying to narrow it down to his model probably because he doesnt trust the advertised value by the manufacturer,

In both context you still did not need to give him the parameters you gave because it wont make any sense to him since he is not a car design or a manufacturer and so wouldnt understand the complexities and intricacies that brought about that simplified formular which for sure engine size will be in but i do not need to know cause am just a freaking end user.

Your tone of answer was meant to ridicule the poster and a few other people sensed that.
I was just putting you to a check. if that is how you are in real life you need to SLOWWWWWWWWW DOWN AND BREATHEEEEEE like we do in YOGA!!!! LOL

it wont be bad to try some coffee too
