Well the VW/Audi specialist i deal with tell me not to use anything else- (mind you my cars chipped) It is expensive though. I think there is a difference - the car feels more responsive. Ive been using 97 RON super unleaded too. I suppose it depends on how flush your feeling.... It doesnt do any hard using normal unleaded.

[badboyV6 4]

that should read 'doesnt do any harm using normal unleaded'

It only costs about 4p a litre more, if you put in 40 litres, that's just an extra £1.60. I'm quite happy to pay that knowing my car's running on the best fuel available.

Sorry, I know I'm dragging this up after a few days. Don't believe the hype.

Higher octane levels in fuel allow you to run a higher compression ratio without getting knocking (partial fuel combustion). Highly tuned engines tend to run high compression ratios, thus needing high-octane fuel.

The VR6 runs 10:1, not particularly high. I use 95 RON in mine and I don't get any knocking, so there's no advantage in me using higher octane fuel. There's nothing in it to actually produce more power.

Dont VW recommend that you use 97 Ron fuel? On the inside of my petrol cap theres a sticker that says 97 Ron so I dont put anything less in it.

i decided to use shell optimax last week. Toped the tank right up. The car did feel more responsive and mpg slightly improved aswell.

[tinny22 11]

thanks for the help. went to motorsport developments they re -mapping specialist they told me to use shell optimax and take my k&n induction

kit off and put the original air box back on they are specialist in live mapping

plmk is a good thing or a bad one

thanks tinny22

Agree with nickbee you don't have to run 97 octane as the vr6 is a modern engine and has knock sensors. Personally I wouldn't bother on a standard engine.

[tinny22 11]

just been quoted 250.00 to have my car re mapped

anybody ese had their car re mapped.my vr running fine but it needs more go

bloody hell thats cheap. Was that a remap or just bog standard chip?

Back on the Optimax subject, Evo mag did a 1000 mile test on 3 different cars a couple of years ago and recorded tiny improvements in performance on all 3.

The real advantage was that Optimax contains a cleaning agent and photos of the valve backs and piston crowns showed a marked reduction in carbon deposits after using Optimax. It seemed to actually get rid of most of the build up of gunk in all 3 engines.

I've used it ever since.

What about BP Ultimate?

off shelf chip done by them (they sell chips to other tuners)

they have been chipping cars since 1980s

first tunner to get 400bhp from cossy back in 80s
