Do you brim the tank?

I generally wait until the light comes on then fill up at the next petrol station , not necessarily to the brim , but until the pump clicks off .

Every now and again I may get to the end of the month and be skint , so might just put £20 £30 or whatever in to keep going till payday .
 
I always brim..except if there is no super diesel in forecourt, then I may half fill.
 
I brim the tank, but then I pay by card (which I settle at the end of each month), so it makes no difference if I put in £40 now, or £20 today and £20 next week.
 
True, the extra mpg would potentially be wiped out by the extra mileage to the petrol station. Maybe not if you have to pass it anyway.

Brings up the do you go to the nearest or cheapest petrol station to fill up. May not be cheaper if its further away.

Premium fuels may mean a bit further trip if you want that extra performance boost, or cleaning agents.
I have the choice of Esso, Shell and Morrisons for fuel where I live. I tend to avoid supermarket fuel (rightly or wrongly, I believe that the fuel there lacks some of the detergent that you get in fuel from the likes of Shell, Esso, Total, BP, etc.), so that removes Morrisons from the list. That leaves me with Esso and Shell. Now, the nozzles at my local Esso station don't trigger the release of the flap in the filler neck that prevents you fuelling with petrol (which usually has a slightly smaller pump nozzle for this purpose), thus preventing my putting diesel into the tank. So I use Shell. Simples.

Interestingly, I spoke to the manager at the local Esso station about this and he said that he often sees MB and BMW drivers attempt to put diesel into their cars and eventually give up and go somewhere else.
 
Usually I fill for £30.00 but if I exceed it I'll fill till £40.00 and again if I don't round it to 0.00 till £50.00. At that point I give up and pay for what I've filled.
If I'm on a trip I fill it to the brim and keep it above 1/4 of a tank.
 
I always brim, with the exception of the SL which doesn't get used much (particularly in winter). So I prefer to keep the level low on that and add fresh fuel when I take it out.
 
Is there a difference between brimming and rimming?
 
I've always brimmed the tank until I got my current car which has a huge tank and exceptional economy. As this car is only used 2 or 3 days per week a full tank would last me 2 months. I worry about the fuel going stale or even of being the wrong seasonal blend so now I wait until the reserve light comes on then add 25 L which takes it back to half full or 33 L. That lasts me one month.

On long runs like holidays I of course fill the tank and the range of 700 miles to reserve is wonderful.
 
Speed school tough me that brimming the tank just wastes the extra fuel carrying the extra weight.

I didn't believe it at first and used to fill up £70 every time but now by only filling up with £60 I'm getting the same mileage as I would filling with £70 saving £10 a tank

I don't believe it at all.
 
Normally fill to the brim, but if I'm driving somewhere where fuel is much cheaper (e.g. away from motorways or into Luxembourg) then I'll put in enough now to fill up there. It's not that I can't afford an expensive tank of fuel, I just resent paying it
Years ago when I was skint and was paying in cash, it was whatever I could afford, sometimes a tenner.
 
I do all my vehicles filling to pump stops as you will still do the same mileage and once done that way your no worse off plus no wasted life at pumps and waiting to pay why waste your life on the forecourt
 
To the brim without fail, unless I've had a massive fail and find myself having to use a motorway service station, then it's just enough to get where I'm going. This has only happened once in the last 5 years or so.

I even wait 10 seconds after the click and squeeze again just to make sure.

Even though at the moment I only ever need unleaded, I make sure I read the label one the pump 3 times and also check the display to make sure I'm getting what I want. 3 cars use Super, one normal unleaded.

Interesting.

I wonder how you could prove this?
 
£10 worth of unleaded is 8.7 litres, 6.4kg.
£10 of diesel is 8.5 litres, 7.2 kg.

6 or 7 kg will not make a significant difference in fuel consumption on an 1800 kg car.
