Always run my LCR on Optimax/V-Power. Have no idea what the previous owner did.

I even run my other halfs Bravo on it! Dunno why it's a 1.2 it's just like I'm lured to the V-Power pump. Good for the pluspoints though!

How do you get a pluspoint card, Can you just pick one up at the petrol station!?

Whats the rewards like!?
 
Ask at the Petrol station or Google Shell Pluspoints.

You pick up a point per litre or petrol, a bonus point per litre of VPower (after collecting a certain amount) and more bonus points if you get over a certain number of points per month.

Rewards vary from charity donations, to shopping vouchers, to magazine subscriptions, to days out to you name it and they do it rewards if you have hundreds of thousands of points!

I collected 5000 points and got a years subscription to Top Gear magazine :D That was the most expensive subscription too.
 
If you get more than 300 liters a quater of v-power on you'r shell plus card they upgrade you to the v power club. Get the chance to get to go on ferrari track days etc.

The points you have to earn per quater on the plus card is:

And if you get upgraded its:

The V-power card is one of those jazzy ones with the corner cut off to make them fit in your wallet easier?

Also , good keyring (doubles as a £1 coin in trolleys) much better than optimax one.

Oe problme I have foud is that it is upto the guy behind the counter to out the right grade fuel into the card machine, our lass has missed out on extra points as they have only put it in as premium:cry:
 
Cupra Ross......Just to clarify, after a google search Roz is the German term/equivelant for Ron. I have no idea if the numbers equal the same though? Pretty strange why they dont just put 95 ron though instead of roz. Doesn't make sense to use 2 differing units of measurement.

Its purely in the translation mate, they are both one and the same thing:

RON = Research Octane Number
ROZ = Reguläre Oktan-Zahl or Regulation Octane Number.

To the naysayers who don't reckon you get more mileage from higher octane fuel. Where did you go to school?

Its simple physics. We know that higher octane fuel is more combustable and therefore requires less volume of fuel to produce the same reaction as a lower octane fuel.

Less fuel required for same output = more miles per gallon.

I can state with full confidence that my Leon 1.8T will do a good 30 miles per tank more on 100 RON fuel than it does on 95 RON fuel. Not that I care, it costs me 42p per litre for BP Ultimate 100 or Shell V-Power 100.
 
hehe :wtf:

Your average German pays about the same price as you do in the UK. The only reason I get it cheap is because a NATO force based in another NATO country is not obliged to pay VAT or fuel duty to the host country. Its the same deal for Americans based in Britain.
 
But it still throws the same amount of fuel ito the chamber that moves up ad down a set number of times that equates to a certain number of turns of the wheel, the higher octain just means it moves up and down faster, thus tuns the wheels faster but it still travels the same distance

NB it is late so whe I read this in the morning I might realise this is complete rubbish LOL

But it's the contents of that fuel that make a difference.

Stupid analogy, but take some plastic explosive and mix it in with some plasticine to make a 10cmx10cm square of it. Now do the same with pure plastic explosive and ignite both. Which do you think will cause the biggest bang?

Now apply that to petrol. If you have one type of petrol with a low octane rating and another with a higher rating and everything else is equal (and at this point I will say yes, I am aware there is more to petrol than the octane rating...), the one with the higher rating is going to create a bigger bang per the same amount of fuel. In turn, a bigger bang means more energy is created, which means more movement... all for the same physical amount of petrol.
 
Basically, the octane rating is a handy-dandy way of measuring how quickly the fuel burns. If 10 litres of 95 RON was run in an engine, next to an engine running 99 or 100 RON fuel.. the 95 RON would run out first, according to theory. The theory being the higher the rating, the slower and more controlled the fuel burns.

In real-life terms, this means that for x amount of engine revolutions, you'd need LESS of 99/100 RON fuel than you would 95. Simplified yet again, this means you get more movement for equal amounts of fuel, IF you use high-octane fuels.

100 RON fuels may give the impression they're loaded with C8H18, but the amount is actually found in very small quantities, along with paraffin, napthene and a load of hydro-carbons, (like Octane). As RobM said, Octane isn't the only pivot factor in the quality of fuel. The need for higher-octane fuels was realised when we took to the skies in WW1 and 2. Higher octane fuels could power aircraft at higher altitudes than lower alternatives.

As we all know, the higher the altitude, the thinner the air. This is bad for engines, let alone planes 10,000 feet up. Problems with air-fuel mixture here could equal fatal stalling. To counter this, turbochargers would put to good use in order to compress the air being forced into the combustion chambers.. to match the density of the air being combusted, more explosive grades of fuel were distilled.. cue the 100RON etc.

And thus ends the chemistry/physics lesson: moral of the story, higher C8H18 rating, more MPG.

woken up yet... your right it may move up and down faster, but this equates to more power. so your saying you will go faster... ok. but if you drive at the same speed as before you will have had to ease of the accelator... and...
use less fuel. ;)

however, you need to nore that higher octane does not mean more power in itself, you can get a better quality fuel that gives more power than a lower quality but higher octane fuel.
IE ron is the resistance to detonation, so you can run different timing and the burnt may be longer, but how much of a 'bang' it gives is down to the fuel quality.

Yup, Andy. That's correct :D

Here's a nifty analogy, if you could knock a bloke out in 5 punches.. but a stronger bloke could do it in 2... he'd only need to throw 2 nifty hooks to achieve the same as the weaker, more French fella. :D
 
People say you pay more money for V-Power but you get more miles, soooo...

If your paying more money then surely your still paying for the extra miles anyway,not exactly as if its free extra mileage?

By the way mine is ran on V-Power as the MPG doesnt really interest me as i just fill up when it needs it :)
 
Well the outlay is higher than that of 95RON, but you go back to the petrol-pump sooner with the lower octane stuff. So the amount you pay for Optimax/V-Power etc. averages out, mile for mile, to be similar to regular unleaded. If you get it. Use expensive V-Power and you won't be back at the pump as quick as 95.

The savings to be had by buying 95RON are short-term and don't equate to any real gains over the months.

Hence why I'll continue buying V-Power.
 
This isn't to start a debate, as each car will of course vary, but I found the car (LCR) had more poke behind it with Tesco 99RON. When I first got it I used VPower and it felt good. I then had to use a tank of Tesco 99RON and it felt a little better, and then better still after the second tank. I did try VPower again a short while ago and the car lost it's edge a bit, just didn't feel as 'sharp'.

Just thought I'd throw that into the mix :)
