Renault Clio 182
Tesco is definately taking over there a brutal company they have a big superstore were we are (Banbury) but have recently opened 3 Tesco express stores all with in about a mile of eachother
SuperFlow AutoDyn 11
Althought i made the same results at Surrey as i did on the above dyno regardless of how the tranmission loss was calculated.
I know what you mean. Those lucky people in St Albans have a shell just before the M25 which is always cheaper than any other garage i have seen... My closest is 16 miles away!!
What were the actual figures at each then at the fly and at the wheels out of interest?
Cheapest I can find.. I decided to be a tight arse and put some petrol in i removed from my dads mates landrover diesel (Had mayb a litre of diesel mixed in it)... It didnt like that stuff, let just say I didnt need the overrun map for those few days :rasp:

Like I said earlier, people don't care

Well then you're having to buy the additives which is money on top of what could of been spent on higher RON fuel, which probably has the additives anyway (as long as it's not mickey mouse branded)

182, 6r GTi
tesco 99 car runs smother and with all the fuel vouchers i get makes it just as cheap as the normal rubbish

i guess you didn't see the 5th gear test then. :nono:
I did some working out years ago, before my ph1 went onto itb's, and i got better mpg on tesco 99 than i did on 95 - it also felt better on 99 - not faster per-say, but I think the best way of putting it in lamens(sp?) terms is it felt more awake on 99. Oh, that mpg was calculated, not based on the dash, and I did 5 tanks of each (from memory) not doing one tank and swapping.
That addtitives did nothing or made your car make less power, TBH I wasnt massively impressed with the quality of the test though, and it only applies to the particular car they tested of course.

No where near...depends on the ECU but it can be straight away. Not sure how though
MK3 GTI golf 16v
clarify " best petrol" if your on about the higher octane stuff, its not necessarily better, its designed for different styled engines. so using it in the wrong car might mean that the cheaper fuel is actually better
I will say this for the nth time..
I went on a tour round Shell Global solutions a few years ago when a mate worked there. (This is where they test oils and fuels on engines, both live road testing and destructive testing).
I witnessed an endoscope going through the valves on an engine that had been on RON-pikey and Vpower on identical engines, identical life, and the difference as quite amazing. The whole of the internals were just cleaner! The injector nozzle was a lot better on Vpower too.
Since getting my 182 I've only put £10 of RON95 (desperate, and no vpower available) all because of what I saw at Shell.

Poorly engineered tat then.
It wasn't a showcase. Its their own personal behind the scenes testing.
172 cup, Impreza P1
Andy Forrest and Bob Rawle, 2 of the most respected Impreza mappers say they would only recommend shell v power or tesco 99. This has been proven over many years of mapping turbo charged cars. Their word is more than good enough for me and so I use it on all my cars and never had any issues. Only 4p per litre more expensive then normal around here.
BP Ultimate is meant to be the worst premium fuel on the Market and I've been told to use normal unleaded before using this stuff in the Impreza.
One other thing to note is the octane rating on tesco 99 has been proven to drop faster than most premium fuels so if you go through a full tank every month it won't be the same rating at the end of the tank as it was at the start. Been told it's only good for about 2 weeks.
BP Ulitimate is shocking. It's a last resort for me, the SX runs bad on it. Better than it would run on regular 95 RON though.
Didnt get an ATW printout from Ktec, but Andy said it did 155WHP after the run.

that's the printout from using the maxogen isn't it? made 183 on stock airbox? Pretty sure your peak losses were ~23/24hp

We back to back tested some 95 ron against vpower on a totally standard octavia VRS 1.8 20vT.
Logging knock and advance with VCDS the 95 was giving massive correction figures, 6 IIRC over all 4 cylinders and 165hp. We drained the fuel while still on the dyno and filled with vpower. The same logs were taken, this time with 0 correction at WOT and an extra 10hp and 10lbft all over.

Be interesting to find out what would happen on a N/A car. I was allways under the impression turbo cars did perform better with the higher octane stuff
Exactly what one would expect to happen really, good to have some specific figures though.
I mentioned earlier about different loads sites being effected differently by a change in octane, effectively on most turbo cars there will be more load sites adversely effected than on an N/A car, and if its a fairly high compression turbo and has had the boost increased to the point where the power is very much knock limited (ie the minimum advance for best torque is half a degree before det) then it will be greatly effected, and if the knock sensor isnt working well enough, could very easily melt as a result.
