Cheapest Petrol & Diesel Discussion Area

Hi,

My local independent Nisa Todays supermarket offers 10p off per litre when you spend £60 or more in store ....and this is not just a temporary offer! I used to work there a few years ago and sometimes found disgarded fuel vouchers in the car park when collecting trolleys, which I gave to my dad to use the next time he filled the car up. I don't think ive ever seen any of the big national supermarkets offering that much of a discount!

People from South Shropshire reading this will probably know that this supermarket is Harry Tuffins in Craven Arms!

I was intrigued to see it claimed in the MSE tips for cheaper fuel that petrol is measured by volume , and that filling at night when it's cool would get you a bit extra .
The measuring chamber would be metal and thus would shrink when colder . Petrol is a liquid and as such would not shrink appreciably compared to the measuring chamber .
So does this not point to topping up in the heat of day when the measuring chamber is larger ?

As previoulsy stated, the amount by which the density of the fuel changes in monetary value is negligable as will the change in the flow meter dimensions if any (I assume it will be a high accurate turbine type meter).

I do believe however that effect of the change in the density of fuel will be greater than the change in any effect on the meter, in addition will not any change in chamber dimensions will be compensated for in rate of rotation of the meter element?

Because it tends to spill...

Haven't you noticed a smear below your filler ?
It 's more noticeable with diesel 'though.

Thats 'cos your not shaking before you put it away Joe:rotfl:

If your fuel cap is leaking :eek: , you should get the gasket replaced as this is a H&S issue should you be involved in a crash!

I always brim it, as it is the most cost effective way for me given the distance to the fuel station, the first clunk is just froth anyway, once that has settled I can usually get another few squeezes in!

i went to Tesco last night after seeing an ad on their website for 5p per litre off if you spend £50 in one transaction.
i did my weekly shop (£120) and was then told the offer didn't apply to N Ireland - total rip off..........

If there is any mileage(sorry:D ) in filling when it is coolest then surely its first thing in the morning. Ground/Tank has had all night to cool down so dawn to mid morning would be best??
Trouble is would you not use it up quicker too??
Maybe I should fill in the morning and drive in the afternoon!!:rotfl:

You are correct a morning fill should be better, this has been stated previously along with a number of other corrections, caveats or additional advice, but I guess the MSE team have no intention of updating the Tips section that heads this thread. :money:

W.r.t. using it faster, yes you will, but as the calorific value/mass will remain constant, it does mean that the performance of the car will increase by the same negligible amount so you will get there a little faster and it should all even out(ish) in the end!:j

Has anyone else noticed the extreme variation in diesel and petrol prices in a 20 mile radius. In my town it is 119.9 at Morrissons for petrol, and yet if i go 15-20 miles at the same supermarket it is 3p a litre cheaper. Why can't they all keep prices about the same? I am really getting to begrudge paying 3p a litre more for the sake of convenience.I wish more people would boycott the overchargers, but I despair to see that no-one does. So I am likely to be one of the few who refuses to pay more than I need to to fill up.

I don't know either - I work at one of two adjacent oil refineries and historically one of the most expensive stations in the area is only 100 yards from the main gate (and is also the brand of one of the refineries!). I guess it is all about market forces and what they can get away with selling it for - they are in business after all!

What always amazes me is the que of people at the 134p petrol, 156p diesel at a small local station less than 2 miles from a Morrisons - are they all mad?

If all the petrol delivery hauliers went on a weeks stike, virtually the whole country would come to a standstill - not that I am advocating that with a recession looming!:eek:

September 2000 refineries picketed for 5 or 6 days, very nearly shut the country down. Never seen the motorways so quiet and anyone out was doing about 55mph

The USA have a strategic petroleum reserve (a reserve of crude oil) that's meant to keep the USA going for up to 2 months.

How fragile are society is being so dependant on oil. Really need to get our skates on doing something about it.
