Super or regular?

[matchboy]

I refuse to believe that the 160 odd bhp Pug is faster than the 210bhp MK6. The Pug still weighs in at 1.2 ton so isn't super light.

maybe miss daisy was driving the gti?!?!

I'm going to put whatever the manual recommends.

Can one of the mk6 owners confirm pls (e.g. Andy?)

I made a mistake, OK!!  I typed the Roman numeral the wrong way round.  When the Pug was new, the equivalent Golf was the Mk III.  Which I didn't buy.  But then shortly afterwards the Mk IV came out, and Clarkson did a head-to-head run-off on them.

The Pug left the Golf  Mk 4 standing.  In 1998.  Look.

That makes much more sense as the MK4 is a heavy old girl with less power.

Didnt mean to bite your head off.

Not at all, my fault entirely.  It's too easy to reverse these Roman numerals.

I could tell when I had my test drive of the Mk VI that it goes like a bat out of hell.  Self-evidently much faster acceleration than the Pug, though I can't say for sure about top speed as I prefer to keep my licence, thank you.

Hard to know if the Pug is going as fast as it did when new, too.  If there has been a gradual change in its 11 years, I wouldn't necessarily notice.  It was always a car that you had to deliberately push if you wanted to fly - it isn't nearly so prone to sneaking you up to 95 when you think you're doing 80 as my previous XR2 was.

The MK6 will feel that much quicker (despite the extra 50bhp) as the turbo gives so much more low end torque compared to the N/A lump in the Pug.

For those that have them, what petrol are you lot putting into your GTIs?

Is it worth the premium for super?  Does it have to be super?

I think the Mk6 might be slightly different.  In the Mk5, it was factory mapped to run on 98 RON juice, but I'm lead to believe the Audi-developed 'valvelift' TSI engines in the very latest cars were set for 95 RON - which is standard, not Super unleaded.  However, the Mk6 GTI may have been specifically mapped for 98 RON too.  What does it say on the fuel filler flap?

Super, and only use a BP garage. BP Ultimate is all I will be putting in my GTI when I get her.

BP Ultimate is shyte.  Way overpriced, and NOT a true 'Super unleaded' - which needs to be 98 RON.  BP Ultimate is only 97 RON.  The Thorney Motorsport tests proved that BP was rubbish.

why BP?   I used to use Optimax all the time for my old type r.  Tesco does 100 Ron, so thats pretty potent.

Tescos is actually 99 RON (well except from their 97 RON stuff which they still sell at certain places!!!!) - same as V-Power.  But Tesco 99 is more stable than V-Power.

I've heard all this before from auto nuts, so somebody explain.  What's the benefit?

For the record, I've never put anything but el cheapo unleaded in the Peuteot GTi, and never even looked at what brand it was.  Like I said, 118,000 miles and 11 and a half years, and counting.

But your Pug was never designed for super unleaded.  Modern high performance engines are, especially if they are direct injection.

What benefits do you get from the pricier petrol (as if it wasn't dear enough!), and how does it work?

Higher octane brews can cope with higher combustion chamber pressures, and can run more 'advance' on the ignition timing - meaning more efficient combustion - and more 'bang for your buck', along with greater fuel economy.  When you run on a lower octane fuel in an engine designed for high ocatane, the ignition timing has to retard, making the combustion process far less efficient - which means it makes less power, and uses more fuel.  And to get the same levels of performance as you would when running on the correct high octane brew, you actually use quite a bit more fuel when using lower octanes.
