Weyro Posted August 5, 2013 Share Posted August 5, 2013 I knows its a highly debated subject but im curious Where i live there is no high octance fuel, so ive been looking at additives off the shelf.Anyone able to recommend one? I know fifth gear did a test on them, but the test was bullshit haha Im just looking to raise the octane rating.Would lead substitute do the job? Since i have no decat would it have any ill effects? Cheers Quote Link to post Share on other sites
mikey4410 Posted August 5, 2013 Share Posted August 5, 2013 As u said,a well conducted test has been done and there a waste of money and pointless.Wasnt aware you can get lead additive ? Quote Link to post Share on other sites
AdamB Posted August 5, 2013 Share Posted August 5, 2013 They don't do nothing and won't raise the octane at all, its all marketing bullshit. The dilution rate has no effect on raising the octane at all, the fuel will only ever be at the octane you put in the tank. Quote Link to post Share on other sites
Weyro Posted August 5, 2013 Author Share Posted August 5, 2013 the test was a bit nonsense though, the whole point of the additive is to "raise octane" but a higher octane in itself does not give more power, it allows you to tune for more power through higher boost and ignition advance Quote Link to post Share on other sites
mikey4410 Posted August 5, 2013 Share Posted August 5, 2013 Hmm,very true.Tbh i have recently started using higher octane,jusr to at least keep det at bay that bit more. Quote Link to post Share on other sites
Chris Green Posted August 5, 2013 Share Posted August 5, 2013 Avoid at all costs - I put a fuel additive in and must have sank to the bottom of the tank rather than mixing. The fuel hoses melted as a result of this. Quote Link to post Share on other sites
Weyro Posted August 5, 2013 Author Share Posted August 5, 2013 I bought the cheapest one haha, its got a fast and furious reference on the back, so it must be good Quote Link to post Share on other sites
Chris Green Posted August 5, 2013 Share Posted August 5, 2013 I bought a NOS one, load of toss to be completely honest. I went on reviews, but I really don't have faith in the stuff. Quote Link to post Share on other sites

Remember if you have 35 litres of 95 RON, then add 1 litre of someting which is supposed to raise it 2 points to say 97 RON, the dilution rate is way in favour of 95 and that's what it stays at. You need aftermarket management/remap to make the most of higher octane anyway to have more ignition lead. Anyway RON ratings mean fuck all, it's the MON rating you need to be looking at.
