Do you buy your fuel in £ or litres, or just fill it up?
How do you judge your fuel consumption?
My current car does 100 miles for each of the top three quarters of the tank so I fill up at about 300 miles or 1/4 on the gauge.

run to the red,
fill to the brim
& calculate
|
|
Me as well.
|
|
Mid 90's 3.2 24v, just fill it up and don't calculate mpg, best not know just how bad it is:-)
|
|
|
|
Run til about about quarter full.
Fill to second cutout. Remember litres. Pay.
Read trip.
Keep grey cells working by mental calculation of MPG.
Reset trip.
|

Ditto

Ditto old crocks & Espada III {P} - most of the time BUT
£20 cash if I use my local filling station due to their "track record" of card incidents.
Then remember to replace my petrol fund with a folded £20 note.

Fill at about a quarter full.
A couple of brim-to-brim tests previously established the trip computer mpg is fairly accurate, so I know the old bus is currently doing 46/47mpg.

I always fill to the brim and feel glad that I won't have to fill up again for well over 500 miles.
|
|
I wish you lot would stop posting about how far you can go between fill ups/how many mpg you get, i try not to think about it:-)
|
When in the bottom quarter, fill to 4 clicks....occasionally check the car computer (as a previous brim to brim showed it was accurate enough for me to get a good idea).
Always use BP and always use Ultimate, unless circs dictate otherwise, but that is fairly unusual.
Same with wife's car...as she's owned it for 4 years and only put fuel in it once (when she was out with her mother and had no choice).
|
|
I used to fill up Mrs P's GTI as well - with Shell Optimax....

Think yourself lucky you don't have to pay to fill your work motor. :-)

I run it till it hits the red, fill it up to the first click, then round it up to the nearest £. Always calculate my mpg - put air in the tyres today, hadnt for ages, been busy and I was 10psi down on all of them, so it looks like I can improve on my current 63 mpg average. I just get standard 95 RON, whats the point in a city car of anything else.
|
Same here...run until the warning light comes on (usually when OBC range reads 60 miles), then fill up and 'round up' to a whole pound. I make a note of the litres bought as well so I can test my mental arithmetic by calculating miles/litre then miles/gallon once back in the car!!

Always get a round number of litres (usually 20). This makes calculations easier, and gives me a rough indication of whether the engine is behaving normally - with the HDi diesel it can (ideally) manage 300 miles. If I am in a graphical mood it is easy to plot the fuel/miles graph with points every 20 up the vertical axis.
Long ago I used to buy a round number of poundsworth, before credit cards became the normal currency. There was a time when it was suggested that if you didn't brim the tank, none would spill out (Metros especially) and any thief wouldn't get quite as far before having to fill up ...

I run it till it hits the red
Mine hasn't got a "red" but when it rings its bell at me I tend to fill it up, though usually until the pump stops me putting any more in rather than brimming it... and I try to use the same pump every time if I can... sad or what...

When feeling flush or going on a long trip I brim it and make a rough calculation of mpg. A lot of the time feel skint so pay more for my petrol by buying it in small quantities (I have the same proletarian approach to all shopping, idiot that I am). I used to bump along the bottom of the tank with a fiver's worth in my Skoda days but with my last car, whose low fuel level light may not have worked - I never really found out - it went up to a tenner. Now when my present car, which has to try really hard to approach 30mpg round town, gives a sudden rude 'ding!' and turns its light on, I have to grit my teeth and put in 20 quid's worth. Usually lasts a few days. But I do a lot of quite short journeys, so use a lot of juice for the mileage.

I fill mine up to the brim ( well 1st click anyway ) on my way home most week nights. In any event never let it go below a quarter full. Saves having to stop during my working day. The quarter full habit comes from having lived in some fairly remote places where running it too low would have been foolhardy. I do a fair bit of driving so it makes some sense to me to keep it topped up. Usually takes anywhere between £25 and £45 plus of course the 20 Marlboro I shouldn't buy at the same time.....( must quit this New Year )
I do OK on the Nectar or Shell points though....
;-)

|
I fill up once a week, on Sundays when the gauge will be showing just under half as i hate having to stop on my journey to, or journey home from work for fuel.
|
|
I tend to put £10 each fill up but how often I do depends on how often I am using the car. I dont like to fill it up because you're just carrying all the weight around (on a small car it does make a difference) and also its more dangerous in the event of an accident.
|
Run down to red then fill to the brim. Never been a tenners worth merchant as I'd be calling in for fuel every day. Which is depressing. Takes quite a while to fill up, too. People call in, refuel, pay and leave and I'm still stood by my car doing a teapot impression.
Never had that when I owned a Fiat 126 during my minimalist period. Twelve quid would fill the thing :-D

But isn't a petrol/air mixture more volatile than petrol on its own?

Yes, the empty bit of a petrol tank is the dangerous bit, unless the full bit leaks.

I should have added: I buy it by worth, always round multiples of five, for convenient, speedy paying without risking handing my plastic over to some bad guy.
|
|
Down to a quarter or thereabouts, brim with tesco 99 or Vpower. Couldn't even hazard a guess how much a litre is. Why bother? What are you going to do? Push it?
|
|
If paying in cash, up to nearest fiver. Quick in and out payment, so quick the cashier doesn't register Ronnie Reagan mask, especially if I'm on my way to a bank job and need to change number plates on the way.
|
|
Strangely enough, filled up the other day and after I put the nozzle back in the pump it clicked up by 1p. What's that all about, then?
|
Fill.
MPG is accurate on wife's CRV computer.
Don't have one on my Forester but generally 50 litres (approx. 11 galls) from light to full = 280-300 miles = 26-27mpg.
|
Fill to the first click when it gets to a quarter of a tank or below, zero trip meter to keep track of it, and curse the small CRV tank again.
Was shocked this weekend on a trip to Blackpool for a family gathering to find that the direct route from the Fens ( A14/M6) was over 60 miles further than coming back via M61/M60/Woodhead/M1/A57/A1 and A47.
We mimsed over woodhead ( sorry Lud) and muttered to all we annoyed that we were going to enjoy the view:)
Filled up at Tesco on leaving Blackpool at £106.9 per litre and saw it was £114.9 on the motorway services.

I have started commuting more on the bike, and subsequently the Volvo isn't doing anything like the mileage it was. Since I've been doing this, I've opted not to lug a full tank around, and have been sticking £40 worth in at a time. A full tank used to last me about 10 days depending on my weekend mileage. Now £40 is lasting me a couple of weeks.

Always wait until it's 'running on fumes' before filling up.
Add whatever I can afford in notes, but always stop just short of a round pound to force the cashier to give a few pennies change - a long story behind that one....
|

Buy about £20 worth every time the red light comes on, unless I'm going further afield than is routine. I try not to get £20 worth exactly. Fuel consumption? Judged infrequently, it should not suddenly change, and if it did so drastically, I think I'd be aware.
I do not buy supermarket petrol, but not because I think it's in any way "iffy".
Brim to empty driving is not quite so economical, by the way.
|
I run the car to a quarter of a tank or a bit less.
Fill to first click, and then usually take it to the next litre.
I then calculate mileage.
|
I'm with Lud, Rattle and FotheringtonThomas, to a degree. I do a quick cost/mileage calculation usually while queueing for a pump (cheapskate, always time it to fill up when I'm passing the Shell station that's cheapest by 2p/litre!)
I try and work out where I'm likely to need to go in the next week and fill up accordingly, ie: Round trip to son's house costs £7, town and back costs £5, therefore having son next week plus need shopping = put in 2x£7 plus £5, call it £20 for cash.
This method usually means I get a little bit left over each week, so in a "flush" week I can keep some petrol in reserve and in a "lean" week I can save a fiver on my fill-up. :-)

Fill to brim after 150 miles - usually around 30ltrs.
|
i normally fill up exactly Half a tank, on my honda jazz, filling up a full tank is not wise as a full tank of petrol is heavier, and your fuel economy goes down, due to the excess weight.
I normally fill up when the light comes on, and always half a tank.
|
|
I tend to fill up to the 2nd click, and pay little or no attention to cost. Thats what you get with a fuel card. When I do look, its about £33 for 250ish miles, which seems quite poor for a diesel Vectra..

5 miles per litre? That's dire ... 23 mpg. Doesn't bear thinking about. :-(
