Default fuel economy

i read a thread here a few weeks ago and am now on my third tank of fuel since then. the thread referred to fill rates etc at the pump and suggested among other things, filling the car slowly rather than as quickly as the pump would go for a few reasons and i thought i'd try it out....

i was averaging approx 225miles/tank, approx 22mpg. the last tank covered 319 miles (mostly a roads and motorways, so some improvement would be expected) returning 32mpg! the one before that covered 259 miles, ave 25mpg. i haven't changed anything else (ie the way i drive)

i couldn't find the other thread to add the results to (if someone knows where it is and can add a link from here that would be helpful ), but thought i would share this info

Its a bit of a bugbear to me this, ppl buy a performance car then start yakking about mpg etc, I just fill the ****** up as needs be, there no other way around it, we all know = motorway miles = more mpg, ragged to **** = less mpg......

Why buy a car and then spent time running a comparison about filling up slowly and filling up fast....just fill it up and ENJOY IT!

It's also better to buy it in the morning whilst it's still cool, before the sunshine warms it up !

Sorry couldn't resist !

P.S. My STI does 25 mpg in the summer, 22 in the winter...

i've never bothered looking at mpg before. i didn't really want to know and as you've said, why buy a performance car if fuel economy is a concern...

Nicely put Jimmy! Went from Chester to Bath last weekend, thought I'd monitor my mpg as its virtually all motorway, see if I could get high 20's. Result? 23 mpg FCUKIT .

Hope youre enjoying the EVO

My ethos is this: Clutches, Brake pads and brake disks for performance cars are very expensive.

So I drive in a manner that requires me to use the brakes and clutch as little as possible. Reading the road ahead and avoiding the need to slow to a complete halt.


The net result is longer brake and clutch life, and also better fuel consumption - as my speed is more constant as I do less needless acelerating and braking.

Brake light bulbs last longer too

from teh link:

9. ‘Supermarket’ petrol is different
The Claim: Fuel sold using docket discounts at supermarket chains is not of the same quality as that which you would buy from a dedicated petrol station.

False. According to the Petrol Retailers Association, there is no difference between the standard petrol you buy from supermarkets or franchised petrol stations. In most cases the petrol or diesel is even produced at the same refinery and delivered in the same trucks. The exception to this is specialist fuels, such as Shell’s Optimax and BP’s Ultimate. In their case, the fuel is enhanced with additives, which produce that brand’s particular properties.

10. Higher grade of petrol, better the fuel economy
The Claim: Buying premium unleaded gives you better fuel mileage, even though your car manual recommends regular unleaded.

False. While it’s true that premium unleaded is a higher-quality fuel, it doesn’t mean your car needs it to achieve good fuel economy. Read your car’s manual first before shelling out a premium for premium that you may not need.
With petrol prices going through the roof, it helps to know exactly what is fact and what is fiction with commonly-held beliefs. That way, we can target real savings in day-to-day motoring.
That will have the Vpower/SUL ***** up in arms

(aimed at the ones with UK cars tuned for 95Ron )
