Great. More reason for fatties like me not to drink it

The most I've had out of a tank of V-power is 405 miles

i used to get better fuel economy from it in the old coupe

It doesn't seem to make any difference whether I use V-power or standard unleaded, I can't seem to get more than 300 miles per tank, even if I drive really conservatively and do lots of motorway cruising. Replaced my thermostat thinking this might improve things, but it hasn't. Can't imagine how some of you guys are getting 350-400 miles per tank

350-400
Amateurs. I managed 505, but a but boring journey 6 Speeders could do better

i was saying this to Dawn (the mrs) that my car seems to do more mpg with v power than the regular unleaded.

makes no odds at all with my coupe, and has never made any odds at all in any of my cars

reg unleaded = 500+ miles on a tank, i did the lakes meet and all the driving around up there, some driving around the lakes on my own on the second day, and back home (not hanging about...) easily in under a tank

Drive it like a diesel, exploiting all the low down smoothness of the five pot and its inherent torque - changing up a gear at around 2000rpm when accelerating, light throttle at all times, 60-65mph max on motorways, taking foot off throttle and coasting towards adverse traffic lights/ roundabouts / lower speed restrictions. .

I probably would get 500 miles to a tank, even without a six speeder, but after a few days of easy driving, I just can't resist the urge to exploit the power. Hence - only 350 miles. Saying that - 360 miles to the last tank worked out around 30mpg, which is pretty good for this sort of performance car. Never expected more than 20-25mpg average TBH.

Is yours a six-speeder? I've heard a six-speeder can easily achieve 450 miles to a tank.
How many MPH to 1000rpm in sixth gear? Sure the five speeder's fifth gear is around 25.1mph to 1000rpm, so just under 3000rpm at 70mph.

at 70 mph mine is at 2,500 in sixth

Can a 6-speed easily be fitted in place of 5-speeder?

i cant imagine how hard i would have to drive mine just to get 300 miles on a tank. i will always come in with well over 350 miles no matter what fuel i use, though i have to stick to V power now as its been remapped to that.

Mabye its other factors involved like a tired thermostat
Unless you all drive like crazy fools

6 speeder ,v power a must (still 98.4 in my area)
on motorway fantastic mpg as you only feather the throttle to stay at 70 / 2600 ish revs...
but ,use the coupe on a few short shopping runs and you can litteraly watch you gauge drop which kills your average on a tank full as does peak district hilly country lanes....( no differant than my daily car )

I got 450miles to tankfull.Running down to france using 98 octaine.

I know im probably teaching granny to suck eggs but I'd like to point out that tyre pressure makes an important difference to fuel economy as well. Making sure you tyres are all at the correct pressure is a must!

I just managed 230 miles on half a tank (of V-Power) and I believe that I've got the thermostat problem so that ain't half bad ....

^^^trouble is, half a tank on the gauge is not half a tank. I reckon you'll get about seventy-five/eighty from that remaining 'half'.

I'll let you know how I get on!

Just been reading a letter to Honest John (The Telegraph's Motoring Expert) from last year Re: V-Power. It's as follows:

I am a psychiatric nurse with a very reliable Toyota Avensis 1.8. I do not buy supermarket petrol. When I have bought ordinary unleaded petrol, the range, according to my computer, was 360 miles. When I filled with either Excelium, (BP) Ultimate or (old Shell) Optimax, the range increased to 402 miles. On Shell V-Power, the computer indicates a range of 529 miles. Does this not prove that the advice of buying the cheapest petrol is a myth and one should be looking for value for money? It costs more, but is better for the engine and works out more economical (my Avensis returns 42mpg). What are your thoughts?
HJ responded thus:

"I am a firm believer in V-Power and of the economy benefit because it allows even my Fiat 500 to pull better from lower revs. It's averaging 51.2mpg, mostly on short runs, compared with official figures of 44.1 Urban and 55.4 Combined."

I handed over a crisp £50 note in exchange for a tankful of the "Ferrari F1 fuel for the road" in my Passat 1.8T 20v yesterday .....

i drove mine trying to keep off boost the other day and i think i was getting about 33 mpg on normal shell fuel which is awesome although in a hurry to get home spoilt all my hard work lol

I notice a small improvement in performance but a huge improvement in economy, it is very obvious and easily worth the higher cost to fill up with v power

Never done the maths with the Fiat, but on my old Saab non-supermarket fuels were worth 2-3 mpg extra. V-Power or whatever was a little more again, but I didn't feel it was worth the extra money - particularly while I was doing 2k a month.

Having said that, the coupe drinks V-Power.

Do Coupes have knock sensors? If so, then great news: they can take advantage of the extra octane rating and alter the spark timing a few degrees to get more power. If they don't, then you're not going to see any difference from the octane rating, just a marginal difference from the alleged cleaning effects of the detergents.

20v engines, both turbo and normally aspirated, have two knock sensors.

Good news then, you'll definitely benefit from the good stuff. I take it 16V engines don't? Please tell me I've been putting the right fuel in all these years!!!

The 16v do have a knock sensor........

16v engines retard on knocking but do not advance. 20v engines advance until a limit, or knocking occurs.

Oh I say!



Okay, I'm outta here------------->

Ok I'm off to Derbyshire next Monday and I'm going to tank up with V power to give it a whirl. Regular as clockwork it's 7 miles per litre with unleaded, [dual carr. all the way except the Biggar road which is 60 mph max.] So can get 350 miles on a long run no bother.

I've noticed though on this long thread that there's a distinct absence of 16vt's admitting to using this fuel - is it trying to tell me something perchance

I only use 95 ron standard petrol as the 16vt doesnt learn from what fuel your using so standard or ypower you wont see any gains the only thing i got from a full tank of vpower was less mpg it was shocking so i stick to standard
