OK, my last word on this let's work on 120 litres over 8 weeks

Example 1 over 8 weeks

60 litres @ 1.20 = £72
60 litres @ 1.10 = £66

Total spend over 8 weeks = £138

Example 2 over 8 weeks

15 litres @ 1.20 = £18
15 litres @ 1.18 = £17.70
15 litres @ 1.15 = £17.25
15 litres @ 1.12 = £16.80

15 litres @ 1.10 = £16.50
15 litres @ 1.08 = £16.20
15 litres @ 1.06 = £15.90
15 litres @ 1.04 = £15.60

Total         £133.95

Saving £ 4.05

Ipso facto - my case rests (as Paddington bear said)

[simon knight]

No Simon! because at the fifth Monday the guy buying 15 litres at a time is already £2.70 up on the guy who bought 60 litres at the higher price.

PLEASE Malc read my example carefully!..there are no 2 guys...just one.

Now please do the maths!

[john tomkins]

Simon, I can see where Malc is coming from....

In your 1st example you buy 60 ltrs
In your 2nd example you buy 120 ltrs

To get the correct maths, you must continue with your 1st example and buy fuel for another 4 weeks.
Dependant on the cost per ltr will determine whether you'll gain or not.

There you go........confusing

[AuRavelling79]

Thank you John...

Simon - no two guys - just one guy doing different things!

[simon knight]

Malc you're wrong and the clue is: Week 9!  Go figure

[birdymiller]

Whichever way you look at it simon if i put £20 in every week and the price keeps coming down for those 4 weeks then it is going to work out cheaper than filling up at the start of the 4 weeks because i will be receiving more fuel for my money.

[AuRavelling79]

OK - week 9 you put in 60 litres at £1 per litre and don't fill up for four weeks - by the start of week 13 you have spent £60 and have an empty tank.

Me - week 9 15L at £1 = £15.00
week 10     15L at 95p = £14.25
week 11     15L at 90p = £13.50
week 12     15L at 85p = £12.75

by the start of week 13 I have spent £55.50 for the same amount of fuel.

We both have empty tanks - your error is you have factored in an extra 60 litres in your first example to take the average from whereas I will buy that extra 60 litres in four instalments on a reducing price...

Others on the forum are seeing this... and it will save them money in a reducing price market.

[richyp]

you can buy red for 120 per gallon

[Dean Aspects]

you can buy red for 120 per gallon

And if you get caught by the DOT they will fine you heavy the farmer near me got caught with it in his lorry and got a £3000 fine

Every so often the dual carriageway i use on almost a daily basis is targeted by them and the police so dont do it

[simon knight]

OK - week 9 you put in 60 litres at £1 per litre and don't fill up for four weeks - by the start of week 13 you have spent £60 and have an empty tank.

week 10     15L at 95p = £14.25
week 11     15L at 90p = £13.50
week 12     15L at 85p = £12.75

No Malc it's week 9 where I catch up. Let me show you:

My 1st 120ltrs cost me £138 making an average of price of 115 per ltr

Your 1st 120ltrs cost you £133.95 making an average price of 111.625 per ltr

OK so far you're ahead.

But on week 9 I buy another 60ltrs @ 100 . This means that in total I've purchased 180ltrs costing £198 which gives an average ltr price of 110

You on week 9 but your usual 15ltrs @ 100. This means that in total you've purchased 135 ltrs costing £148.95 which gives an average ltr price of 110.33.

By the end of week 12 you'll be ahead again...but as soon as I do my 60ltr fill on week 13 we're back to evens.

[simon knight]

Oh, the reason for you're average on week 9 being 110.33 against my 110 is because I've bought more at the lower price.

gor blimey get a life the pair of you,i wonder which one of you
will take your ball home first

[jeff1]

Morrisons 98p per/L today

[Oakley Windows]

Morrisons 98p per/L today

They can start all over again 

[Bobs Window Cleaning]

You 2 gave me a headache

[Dean Aspects]

Morrisons 98p per/L today

Isnt that for petrol though the Morrisons near here is 110p for diesel and 98p for petrol

[AuRavelling79]

Simon, when you do your 13 week fill up you've put in more litres than me - you've got to have exactly the same amount of litres to work your average from. You add in another 60 litres and it skews the average - can't you see that?

Ok Malc, let's take your last example:

15ltr @ 100p = £15
15ltr @   95p = £14.25
15ltr @   90p = £13.50
15ltr @   85p = £12.75

Total spend = £55.50

Me: 30ltr @ 100p =£30
       30ltr @  85p  =£25.50

Total spend = £55.50

Where is your advantage?

Simon i am with Malc on this one
If you use your diesel at the same rate i.e at 30 ltr a time then you would purchase your second 30ltr at 90p not 85p not that it matters as i only started this thread to see what prices were around the country 

[AuRavelling79]

You've moved the goal posts Simon... 30L to my 15 instead of 60 to my 15 on the first fill; but anyway

Assuming we use fuel at the same rate -

Week one - I put in 15L you put in 30L at £1.00

At the end of week one I put in another 15L at 95p you don't cuz you've got 15 left.

At the end of week two we both have empty tanks (I've used my second 15L you've used up your original 30L)


I've bought 15L at £1 and 15L at 95p and spent £29.25

You've bought 30L at £1 and spent £30


We both have empty tanks and you can't put 30L in your tank at 85p because the price at the end of our both using 30L is not 85p, it's 90p!


Modified to add - Dean - you got your post in before me!
