Lots of independant tests have found it to be a noticeable amount better, wil lhave to dig out that Perfomance ford fuel test, results were amazing, std 95 ron fuel was approx 505BHP, tescos 99ron was abour 515BHP, BP ultimate was about 526BHP and V power about 534BHP IIRC, they ran a T4 8 injector engine on it on the dyno back to back, and advanced the ignition to make best use of the fuels

tescos 99 is eco-etanol so needs anteratons to the timing to get the best out of it but as a stop gap while there is no v power it would be fine
i tryed the v power in the B10 once & got crap mpg i have been useing bp super but as its 7p a L more than tesco i tryed that & got 170miles out of Ł30 & thats not bad for a 3.2 n/a bus

If you go the other way and put in a higher than 99 RON say 100 or 104 (like racing fuel) does it give you more power because the ECU recognizes the higher octane OR do you have to remap the ECU to tell it that it is a higher octane and therefore will give more power?

i also use tesco for fuel, paying for it on a tesco credit card and get loads of clubcard points. these can be used for loads of things at 4x the value of vouchers that you get (e.g. i used eurotunnel in march and used Ł40 of vouchers to pay for a Ł160 crossing

I've gotta say although my car which has a VW 1.8T engine which runs on 95 fuel all day long only feels better with Tesco 99! I've tried everything else, V Power, Ultimate, 97 ron and don't seem to feel anything but with Tesco stuff it pulls so much better plus you get clubcard points!
