  1. high octane fuel really worth it on FR?

    I saw this interesting bit from fifth gear. They tested three different cars (clio, golf gti mk5, and imprezza) and three different fuels. On the GTi the difference between the 95 "supermarket" fuel and the Shell Optimax showed only a 5 HP difference. they didn't test for mpg but still, really...

    Octane Booster - LCR Stage 1

    Hello all. Just spent about 20mins with the old search function and have learnt a little about the above, but most posts seem to trail off and don't get concluded. Anyway, I have been offered a bottle of this octane booster by a friend prior to going on the Dyno. He runs it in his Impreza...

    Octane booster??

    Has anyone with an SPS+ sampled the effects of an octane booster on their timing advance? Im looking at the Millers octane booster (around £4 for treating 50 litres) which suggests an increase of 2 RON. I already use Vpower which is a claimed 99 RON. Since the new BP 102 RON is around...
  5. 95 or 100 octane. What fuel do you use??

    On the fuel cap, it says the manufacture recommends 95. After i had the Unitronic program put on the Cupra, my tuner said to use only 100 which i have been doing. There was a few times where i had to use 95 because 100 was not available. I definitely notice a small difference with the better...

    Hi, Just a quick for information only post: (I did use the search to see if this was already up anywhere else) I was speaking with my local Shell petrol station yesterday (Hilsea, Portsmouth) and we got onto the subject of fuel octane rating. I had heard some rumors about the optimax...

    Has anyone else tried Tesco's new 99 Octane fuel?? I have put 2 tankfulls in my Leon Cupra R,and to be honest i am amazed at the difference in the way the car goes.Most people notice with the LCR that it starts to run out of puff as you get upto 5500-6000 revs,even after a remap(like...
  10. Vag Com logs - Comparing with and without octane booster

    I run my car all the time on BP Ultimate as there isnt a shell garage near me and ive heard some people prefer Ultimate to Optimax anyway. I recently brought 10 bottles of Millers Octane Booster (2 ron) I did some logs before and after adding the octane booster to a full tank of BP...

  12. Octane - how many points equate to a RON?

    Octane Boosters......... Millers CVL Turbo adds up to 4 RON, NOS Racing Formula adds up to 7 Points. How many points equate to 1 RON? I've tried CVL Turbo with excellent results, has anybody tried NOS Racing Formula? Its a lot more expensive than CVL Turbo though at £19.99 (RRP) against...

    Tesco 99 octane

    Filled up with this stuff for the first time! Impressed, normaly use optimax only but had to give this a go! initial impressions, seriously enhanced gear changing around town, nice idle and goes better than optimax. One down side is noise! on acceleration you can notice a lot of manifold style...
