Don't believe the dash, I was getting 80+ mpg according to one I had lol :eek:

IMO no dash can be believed so. Same with speedometers. Must try saying that to a guard next time.

Though i say my MPG is pretty close. MPG will also depend on whats in the car, tire pressures, condition of engine, etc. There is nothing else but myself in my car and boot is empty, no additional weight only spare wheel and tools. 50euro of fuel will do me for the week, 35 miles x 2 a day x 5 times a week which is around 350 miles a week and i get more with weekend short drives which i think isnt bad. MPG could still be wrong though, I agree.

2004 Toyota Avensis 2.0 D4D - 53 mpg combined.

Drops to the 40 mpg mark around town but its mainly used on main roads.

Well my dashboard tells me that, i dont have to calculate it or anything. I just reset it everytime i fill my car and i only fill it to half tank. I also drive very economical with little reving changing through the gears smoothly and light use of accelerator and still doing the speed limit.

So you believe everything you read on a computer screen....surely not.

Well no but use it as an approx estimate. But it must be close enough I would think?

As above, not entirely true in all cases.. I get over 1300 kms from a full tank of about 67 litres with the trip computer reporting 55.4mpg which is fairly accurate.

520D LCI btw, with 70% motorway driving..

Piriz · 04-11-2012 08:43PM

650 Ginge...without using the cars computer or the website you suggest (which is basing MPG on other peoples cars) what is the best way to calculate MPG?

kuro2k · 04-11-2012 08:44PM

1996 3rd Gen Toyota Hilux Surf
231,500 km
3.0 Turbo Diesel

23.71 mpg: Average (Over 29,500 km since June 2011)
20.10 mpg: Worst (city driving)
32.00 mpg: Best (motorway driving @ 100km/h)

I use the "road trip" iphone app to calculate

Fill the tank, reset the odometer, drive then refill, take note of the odometer reading and mileage, calculate from that, that's the only way I'd measure it.

There is no way a 520d is getting 55 unless you never get over 80k/h. The average on 100's of 520d on spritmonitor is 41.

You'd be surprised. Good friend of mine drives an 08' manual 520d. Averages 53mpg and he fairly shifts along.

how would one calculate it? Is this method correct? My approach would be

1. Find out size of fuel tank full. e.g. 80litre tank.

2. Find out your miles covered from full to empty (i.e red light) e.g. 625 miles

3. Divide miles covered by size of tank to find how many miles per litre. e.g. 625/80 = 7.81 miles per litre

4. Convert to gallons. 1 gallon = approx. 4.5 litres

7.81x 4.5= 35.14mpg

correct?

45mpg, 1997 1L Swift when driving the socks off it/sitting in traffic.
Stay steady @ 50mph and it rises closer to 55-60mpg.

In a car like that (I've been lucky enough to drive one over in Spain) it's not about the miles per gallon, it's the smiles per gallon

Back to reality, my soulless SUV wannabe (Qashqai+2) gets 33 around town, around 45 on motorways and the missus' car (Micra 1.2 sport) gets around 37 around town and about 41 on motorways (the gearing seems to be more suitable for low speeds, it does north of 3000 rpm at motorway speeds in 5th). The figures for her car are when I drive it, she revs the sh1te out of it adding a good 10% to the consumption

Much simpler than that, just follow the brim technique as I described, that way you don't have to end up stuck on the side of the road to find out.

Also, AFIK some manufacturers round off the size of their tanks, how can you be sure the tank is exactly 80l?
Also, how can you be sure the red light comes on when it's empty? Once again, most manufacturer's that I know always built in a mini reserve.

Brim the tank and reset the odo. Drive until its nearly empty or the light comes on and then brim it again. Take the mileage from the odo and use the amount of litres it took to brim the tank again and do the calculations

Toyota 4runner 3.0td

Last weeks fills gave me:

28.36mpg / 9.95l/100km

26.45mpg/ 10.67l/100km

70% motorway 30% city/country
And that is miserly driving, never over 90kph, tuck behind lorrys and gentle accel & a lot of engine braking where possible

If i drive like a normal person i get about 20-24 mpg and if i go off road it can go down to about 16.

Fill tank to brim, reset km counter, drive it until near empty, it doesn't have to be exactly empty or red light, just a point near empty.
Fill tank to brim again and note exactly how many litres it took to refill. Then divide the km travelled by the litres it took to refill.

Example, car took 45.5 litres to refill since you last filled and you travelled 900km in that time,

My maths is brutal, i'm sure there is some formula here but to get l/100km I then do this...

900/45.5 = 19.78km travelled per litre used.
100/19.78 = 5.05 litres used per 100km travelled.

I have an interest in this lately myself.

Honda civic 2006 ep1 (old shape) 1.4l

I took some tips off an American hypermiler website called cleanmpg.com and have gone from 7.9 l/100km (36mpg) to 4.9 l/100km (58mpg).

All i changed was driving habits, i don't go over 100kph unless necessary, i go 80kph mostly, pumped tyres to maximum sidewall px, treat accelerator like an egg. Lots more small things all on that website.

Just to clarify im not driving like a granny with lines of cars behind me, its just anticipating better. Since i started doing this its actually incredible the amount of people who speed and get pissed off behind people who do the speed limit. not on a high horse or anything i used to constantly break the limit and get angry with 'slow' drivers.

Forgot to say its approx 60% urban and 40% motorway. Also im not relying on the trip computer mpg reading i fill the near empty tank and divide in km's....

got the new shape 2006. i got her to go at 5.7L for 8000km. been more stuck for time recently and running at 6.3L for the last 12000km.

when i first got her(first car), drove it like i thought it was a ferrari and i was running at 7.8L.

there is some difference in the honda's from normal driving vs speeding compared to other cars

Yeah, you don't buy one for the fuel economy

When belting along proper you can see the fuel gauge just dropping and you can just feel the money draining from your wallet.

Worth every last penny

Mentioned this before: if you have an iphone Road Trip is a great app for recording mileage.
