Is the engine tuned?

[Tom]

It is indeed..

[MarkTD]

Well first give it a proper service & how far have you gone with the tuning?

[Tom]

Only stage 1 so not major... Need to service but havent got the money at the minute :/

[darrenjlobb]

Lol, you doubled the hp, the mpg isnt going to stay the same if you drive it hard all the time...the MPG will always remain the same if you use the same amount of power, your not, so its going to decrease...and dont tell me you still drive it like a granny all the time like it used to be lol.

[Toms306]

Have you actually measured the mpg? Might not be as bad as you think...the price of diesel makes it look bad lol!!

[Blaze tub tom]

My old bog standard dtub used to get 500+ on a tank and now I got this 1 it only does 380

[Tom]

I dont drive like no granny... I was forced to because it was unbeleivably slow Just thought i've been driving the same style since it was tuned and just this week i seemed to be putting in lots more fuel :/ I havent properly measured it just guessing by how often i put fuel in lol
Its probably me just being a noob as usual lol

[Atterz]

Your driving it like a bellend really, lets be honest now?

[Dum-Dum]

Work it out then see if its worth complaining.


Also your not running v power diesel are you? my XUD hated it.

[Tom]

Nope no v power... i dont use supermarket stuff though :/ I havent worked it out but fuel light on i put 10quid in and pressed the reset on mile thing and then 36 miles later lights back and needles way into the white block on the empty side now that aint right.. my friends zetec s does 50 miles to 10quid easy :/

[mark_airey]

But if your well into the fuel light £10 will hardly even add enough fuel to the tank to turn the light off!

[Tom]

No the light came on then i put 10 quid in lol it wassnt on for very long

[Dum-Dum]

The lights on these arent amazing.


Fill it to the brim, drive 100 miles and then brim it again.

That way you can work out your actual mpg.

Its pay day so you should be able to afford it.

I will warn you the XUD isnt the most economical of cars. My tuned one running on veg averaged less than 40mpg and the std one got just over.

[silverzx]

Kind of agree with Chris here, they defiantly aren't as good on the miles as the HDi but at £1 a litre for veg it hardly matters.

[Ben Jay]

If you have an iphone or android there are plenty of apps out there to calculate mpg!

[Ben]

You don't need an app!

Just divide the miles you've done by the number of litres used, then times by 4.5 = MPG

[Tom]

How can you tell how many liters you've used though i dont have the money to be brimming the tank :/

[4WayDiablo]

How can you tell how many liters you've used though i dont have the money to be brimming the tank :/

you cant really unless you brim it
but you can work it out over time as said above just note how many miles youve covered after putting in more and more litres

[Tom]

Think i'll start on monday and note everytime i put fuel in and how much.. hopefully it'll be bit better as i just changed my fuel filter

[Toms306]

How can you tell how many liters you've used though i dont have the money to be brimming the tank :/

I don't understand this.....either you stick in 6 times £10 over say a fortnight........or you stick in 1 times £60 over a fortnight.........its the same lol.... :?

[Tom]

I never have that much money lol :/

[Toms306]

I never have that much money lol :/

But you still put a tankful in......either in tenners, or all at once lol......whats the difference?

Just a quick way to work out rough mpg in your head; At 45mpg (which you should easily get from a dt!) the litres match the miles - so a tenner = 7 litres = 70 miles at 45mpg. If youre really only getting 30 odd miles then thats 22mpg.............

[Tom]

In the end that 10 did stretch to 80miles but then i dont know how much fuel i had left haha the light was on for ages i just kept driving

[Toms306]

Yeah you can drive pretty far on red lights i find, usually well over a gallon left!!

[declantg]

Im always in the red no a days

[Tom]

Yeah im in the red all the time haha

[Tom]

160miles to 30quid (20litres)? Thats not right is it

[4WayDiablo]

Thats still nearly 40mpg isnt it?
