GF's new car "micra 1.5td" MPG AWSOME

[dave j gtt]

It is a 2009 mirca turbo diesel.

I was going slow but thats not the point. it took 1 hours driving more and halfed the price of fuel.

filled tank to brim, managed 172 miles and gauge still above 3/4 mark.

I drove 90 mile last night avg 72 mpg, today i drove the rest avg 90 mpg and sat thinking surely not haha i mean if each 1/4 of tank i get about 180 miles that would mean £45 to fill tank, 1/4 x 180miles = 720miles of full tank

Going to go fill it back up to brim to see how much money that costs.

In recent weeks gf goes same journey and gets around 400mile on a tank 56 mpg roughley, its about the most miles shes come home with on in car MPG gauge.

Anyone else got any other model diesel thats really good on juice ?????

[Biggs]

My old Pug 406 110 hdi was amazing.

A tenner would last 3 weeks, on a daily 50 mile commute.

[djinuk]

call me dippy but are you saying u got 750 miles to a tenner?

[Brigsy]

My daily driver xantia hdi 90 always pulls between 650-700 miles on a tank (65ltr), mostly urban driving. Modern diesels ftw

[robbie506]

call me dippy but are you saying u got 750 miles to a tenner?

i want that sort of milage!!!

i do 40 miles a day plus about 100-150 at the weekend spend on average £75 a week fuel.

i want my 307 110 back about £30 for the same usage as the megane!

[djinuk]

my 306 1.9 td it returning about 60 to a tenner which is terrible , however with the fresh engine in, bosch fuel pump and lots of veg oil i should be sorted

[DaveMayGTT]

polo bluemotion does a fairly good job on miles, if its not short trips all the time then 66mpg seems to be about the norm with mixed driving. If you drove gentle everywhere i think you would expect to be around the 70mpg mark

[Sparkie]

my 306 1.9 td it returning about 60 to a tenner which is terrible , however with the fresh engine in, bosch fuel pump and lots of veg oil i should be sorted

i used to have a zx volcane td, which also did 60miles to £10...

now i have a megane scenic dti, and that does 280miles to £30....

[Trevhib]

Corsa 3pot 1.0 litre.

£22.50 (20 litres) - 225 miles (10p a mile). 51mpg. That's all here and there town-type driving, no longer journeys.

This makes owning the car bearable -- just.

[Biggs]

Ok i may have over exaggerated a tad, a tenner would see me good for at least 300 miles though.

Another plus point was that i was able to get free diesel from all the scrap cars where i worked.

thats still over 100 mpg. lucky if i get 35 mpg

[Matt@CodeRedMotorsports]

Unloaded, my 'borrowed' extra van is good for around 200 miles on £20 of diesel.... No veggie oil yet.......
My 'breathed on' Fiat cinquecento Sporting, went from my place in Tunbridge Wells loaded to the max with equipment to Matt (jesus in a 5's) place near Bristol and back on a tank of fuel...... Over 380 miles......

[SCHWARTZ]

my car has been on the same tank of fuel for about a year now. only moved about 3ft tbh

[jimmy_b]

my gf has a 2004 clio 1.5 dci65. she does a 60-65mile commute each day to and from work (350-400miles) and only ever puts in £30 (25l ish)

we took it to wales and back from suffolk on less than half a tank and averaged 74.6mpg!!!

couldnt believe it when im only getting about 20mpg from my 5 lol

LPG is the way forward. Costs me about 10p a mile on my 1999 E39 520i, and I get heated leather, A/C, bags of space, safety, and a much nicer car to look at / drive than a corsa

did you buy it with LPG fitted, or did you have it fitted ?

I Quite fancy a duel fuel Astra van or might end up getting the 1.9 cdti still unsure and undecided , any one know out about then?

this was what car i wanted her to get, but her dad got her £2000 off this car so work out rather cheap

First place pulled up to take a picture

Alright showoff

However, in my favour the Corsa is cheaper to buy and insure, there's less to go wrong, cheaper spare parts and no LPG system to service.

I'm trying for a record with my latest 20 litres. It's going very well thus far. Short-shifting, using momentum and coasting are becoming second nature as I found I was doing the same thing when driving the Mrs' Escort the other day. What a loser

[Tiny Tim]

What a loser

You said it Trev

I gave up worrying about cost of fuel/MPG a long time ago. Mind you, im younger than you

perfect if you mean what i think, the accelarating pedal needs the finest of contacts in my case. and will roll away to and extent down hills and slowing up them, that my coasting.... to much pedal results in car holding speed.....

When you say coasting do you mean clutch in and out of gear?

You would need a big hill or long down hill road for that to save you money. as each gear change or new squirt of fuel from ecu will result in it costing you more the less changes the ecu reads the better on fuel it will be.

Or at least thats what i think Coasting with thorttle off or and only using a tiny bit is
Just have work out your max speed in 3rd 4th and 5th gear so you can achive min fuel usage i surpose.

it is boring driving so slow and if you want to go any were quick its near impossible

[AlexS]

All this MPG talk depresses me. I struggle to get 27mpg.

[Trevhib]

Coasting = pull out of gear at speed, allow car to roll.

Often this will be up to a set of lights or to the back of a queue of cars whereby I'd have to stop/use gears/start once more in any case. Other times, just using momentum down hills and being sweet with balancing revs/road speed when bringing the power back in continue on my merry way.

I've measured over 1/4 of a mile savings in some cases and mostly between .1 to .2 miles. There's no way that's less cost effective than staying in gear and feathering the throttle.

Tim - Worrying about fuel consumption is not age related, it is a direct result of current income issues. Or did you think I actually had a choice when I decided to buy the Corsa

no i agree with what you have said and about having no choice in the matter, anticipation, balance right, jobs a good un

[robbie506]

there was a report out some time last year which said coasting uses more fuel than using low gears to slow the car. i will see if i can find it.

How much did the corsa cost? Mine was £2000 without LPG, then I bought a lower spec 520i (with the same engine) with LPG, swapped all the LPG stuff over (inlet mani with injectors, tank, etc..) to my car and sold the new car back on, for exactly what I bought it for, got it certified and job done. All in, with certification, etc, it stood me at about £150. Also, it doesn't need much servicing, just a new fuel filter every year or so.

[Trevhib]

That's a top way of doing it Bric and I repsect it

However, how much cost can one attribute to the time spent understanding LPG systems, faffing around swapping parts over, getting it certified and time covered advertising & selling motors - all for a big car with a small engine that might have something simple but expensive go wrong with it next week that blows the whole 'cheap motoring' scenario out of the water despite the effort put in?

The W reg Corsa cost £675 and that came with one owner, FSH, 12months MOT, 6months tax and serviced 4 weeks prior. The one thing I really really miss over anything else is A/C.

[clee]

Coasting is illegal as you are not in full control of said motor vehicle innit

[wolvo]

Theres 2 serious problems about getting so many mpg out of a diesel nissan micra........

1) It's a MICRA

2) It's a DIESEL

Although i must admit modern diesels are good engines a diesel car will always be exactly that ... a stinky oil burner (im a diesel engineer) and id never own one even if it did 1000 mpg !. Id rather have a big engined lpg conversion which despite what some ppl think is very cheap to install and very easy to maintain (HKL in birmingham sell all parts needed cheap as chips.... service kits for cobra gas units around a tenner)

[Penfold aka The Dealer]

Coasting is illegal as you are not in full control of said motor vehicle innit

also coasting on medern engines uses more fuel than leaving it in gear!!

But driving style, tyres have a lot to do with MPG!

[AlexS]

But driving style, tyres have a lot to do with MPG!

Also, size matters.............................or so I've been told.

[Trevhib]

Coasting is illegal as you are not in full control of said motor vehicle innit

So is extortion - road tax, fuel tax.

I'll take my chances and let the plod prove an occasion when I've actually coasted my motor beyond the legal distance allowed. Hmmm, is there a legal distance associated with coasting? Because I can guarantee most people do it to one degree or another when pulling up.

[Trevhib]

there was a report out some time last year which said coasting uses more fuel than using low gears to slow the car. i will see if i can find it.

If that is true, the following must therefore be true:

- You will run out of fuel more quickly being sat stationary ticking over (id est coasting), than driving down a never ending decline in gear, feathering an open throttle.

If there's some evidence for this I will read it and change my stance.

[robbie506]

off the AA web site.


Coasting - does it help save fuel?

Coasting - rolling downhill or approaching a junction with the car out of gear - is inadvisable because the driver doesn't have full control of the vehicle, though it used to be quite a common practice to save fuel.

• You lose the ability to suddenly accelerate out of tricky situations.
• You lose engine braking which takes some of the load off the brakes on down hill stretches and helps to avoid brake fade - overheated brakes require harder pedal pressures to stop the vehicle.

These days, coasting is still inadvisable and changes in vehicle fuel systems mean it won't save you fuel either.
Old car with carburettor - take your foot off the accelerator pedal with the car in gear and fuel is still drawn through into the engine. Fuel savings could be made by coasting out of gear.
Modern car with electronic engine management - fuel and ignition systems are effectively combined and controlled by one Electronic Control Unit (ECU). Take your foot off the accelerator and the ECU cuts the fuel supply to the injectors anyway so there's nothing to be gained by coasting.
Modern diesel engines - these also have the ability to shut off the fuel when you take your foot off the accelerator.

<sigh> In essence, what they are suggesting is that coming completely off the throttle either in or out of gear means the engine sees the same level of fuel. I agree but then you'll slow down much faster and wont advance nearly as far if you leave it in gear having come off the throttle because drive train friction and engine braking will slow you down more quickly!

Thier angle is a safety one, they simply don't want you to coast and are twisting the words about fuel savings to try and encourage people to conform. You wont save any physical fuel but YOU WILL TRAVEL FURTHER DOWN THE ROAD. If you go further, your overall fuel economy improves.....

[robbie506]

this could turn into one big debate but i do agree with what your saying but i dont think there will ever be a definative answer.

[clee]

You could always save a liter by using that new Shell stuff
For the last two years I've been getting about 0.5mpg in the GTA ..........

im using the new shell stuff and for the first time sice owning the car i havent had to fill up today i will make it till tomorrow so its a big from me still just about to go into red but not quite there yet.

[Trevhib]

New shell stuff? Is it a more expensive alternative or is it shall standard fare now?

[Trevhib]

this could turn into one big debate but i do agree with what your saying but i dont think there will ever be a definative answer.

If you agree bud then there's no need for a big debate. I've not seen anything on the subject to suggest there's an MPG advantage available by me changing driving styles so it's all gravy.

I'm halfway through my mega-miser fuel saving test on my current 20 litres. I'll report on results when they come in

This is the only bit of interest I have driving the Corsa

im starting a fuel save tomorrow see what i can save over a three week period. let us know what the results are.

and i never meant a big debate between you and me but between a few people who say coast and others who say stay in gear if you get what i mean god i need to go to bed.

[The new Bill J]

The MPG of my car is crap. However, it's consistently crap. I've tried driving a full tank in full-blown fuel save mode. A/c off, not going over 3k revs, not using boost, no excessive idling. I got no more miles than I get driving 'normally' (A/c on all the time, a bit of foot down, some back roads, motorways, Sunday blast etc etc.....).

[Trevhib]

Bill, I had the same with the Honda Prelude 2.2vti auto. 22mpg no matter what I feckin' did or didn't do

Fair play - either way works really. The reason I did it the way I did was because I was driving 100 miles on the motorway each day, and wanted something that offered a good amount of safety if I were to get into an accident, and with a 4 star N-Cap rating, weighing 1500kg, and being built like a tank, it was the perfect car really!

Had something gone wrong with it (which it did, a few times... thermostat, windscreen wiper motor arm, pas pump), I fixed it myself. Really easy cars to work on, and not as expensive as most people think.

Anyway, now I'm back to working 1.5 miles from work, I'm getting a big fat 535i Sport to replace it

[The new Bill J]

I can't fault your logic bud, especially for your long journey scenario. Plus, I would certainly prefer to travel around in your Beemer than my Vauxhall no matter how far I was travelling.

[Trevhib]

Yeah and I wish I'd had some power and a manual gearbox!

22mpg with the performance I got (not bad but not worth that sort of mpg), was about as acceptable to me as a kick in the spuds.

you selling this car then ?? pm me some details if so, and maybe a few cheeky pictures and a price

[Trevhib]

You could always save a liter by using that new Shell stuff

Aha, I've seen it advertised for the first time this morning on the telly. Shell FuelSave.

Going to check out the price and I'll have a go. Not seen any literature yet so don't know how it allegedly makes the savings.

[robbie506]

i think it works and its only £1.12 per litre from my local.
