I need to fill it or I could be doing it again, same day!

£50 a time. Nowadays, I normally only need to fill up each car once a month, twice at the most. This takes me from around 1/4 full to almost full, which avoids the problems associated with a low fuel level whilst maintaining an adequate reserve.

In the past, I often needed to fill up several times a week, and then I would brim the tank to the nearest £. I appreciate that 'brim to brim' also yields an accurate consumption check, but entering my purchases onto a spreadsheet enables me to calculate my MPG even more accurately. :thumbs_up:

I find that the round number of £££ makes life easier when it comes to reconciling credit card statements and preparing accounts.

Fill up when down to a quarter or less. This way I can wait until at a cheaper station and also check the mpg. Started doing this when the old 740's fuel gauge went wrong and I knew that at a certain mileage on the trip I needed to start looking around again for a garage.

Did once have someone say that the extra weight of a full tank reduces the mpg so any savings are wiped out but at up to 6 pence a litre (27 pence a gallon) saving or nearly £5 a tankful I doubt it.

Anyway buying fuel is like buying tyres, a distress purchase so the fewer times I do it the better I feel.

Light comes on, fill up next time I am near Tesco, sorted.

The light comes on in my V70 with about 2 gallons still in the tank so plenty of time to find a petrol station, but then I fill it to the top, queuing at a petrol station for less than a tank makes no sense for me, but I suppose if I did very little mileage I might be inclined not to fill it right up.

On my regular weekly round, when I get down to ¼ full on the gauge, I fill up to the brim at the Shell on the way home at the end of that day. Actually to the nearest full litre that I think I can get in, it's easier to remember for the real MPG figure calculation when I get home, plus I get the maximum loyalty points for my money over time :)

Fill up for me. Not quite into two months ownership of my V60 T4 and I'm keen to measure mpg with my phone app.

Taking 450 miles per tankful, 12000 miles per year, 10 minutes out of your way to fill and a 40 year driving career that adds up to .............................. nearly 180 hours in forecourts.
Putting in a tenner and it's starting to look like a full time job for the best part of a year.

Interesting responses. I didn't think it was going to be so clear cut!

For ref, I'm of the fill-it-up persuasion, as that allows me to calculate tank-to-tank figures. I have the data for EVERY tank of fuel I've put into every single car I've ever owned.

Depends on what I'm up to..
If I go long way, there's no question- fuul and then some more.
But typically I'll put only enough to last me few days. So sometimes a tenner, sometimes 50..
There are weeks that Welma is in use daily, there are weeks that she goes out only on Sunday.
A lot depends on where do I work on given day/week.
