Yeah, V power's great for high comp engines. But olly's isnt a high comp engine lol It would probably be perfectly happy on 95!
But as you say, if you have plenty of V power about, you might just as well.

NOT at all, enough tests have been done to prove that they are no where near the same.
Less of a problem on atmo engines, huge problem with turbo engines.
A couple of my mates run some serious monitoring gear in their cars whilst mapping and when their not and it is worrying to see the difference from fuels and even in some cases the differences with or without a splitter fitted !
Tesco 99RON has been proven better than V-Power.
And it keeps its octane rating.
V-Power "degrades"
Im not saying theres no difference, im saying on Ollys engine the difference will be so minimal as far as performance goes, it makes no odds whatsoever lolQuote:

My old engine used to mildly det on 95 and run fine on 98, which proves there is a difference, however i was running a ludicrous comp ratio lol Ollys block is standard, so in all fairness super would be more than adequate imo :)
I know you know your stuff Jonlem, im not arguing with you here lol lol Just stating my opinion based on my experience with many XE's!
All the more reason to map on V-power then, if you cant get it you end up on better fuel, rather than vice versa.
I'm currently using the same spec engine as Ollys and I have run it on both fuels, the difference is ridiculous :eek:Quote:

Anyway this isn't a topic about fuels and octane ratings so we can carry this on elsewhere another time :thumb:
Lee- totally fair points there mate, I have no doubt you have also had the luck of being around so many crap and so many nice xe's that we could go on all day about what we have learnt.
A xe with a mildly skimmed head will det on 95, I have the piston to prove it LOL
Adam, this is true but with Tesco's past record I think I'll buy my fuel from someone who hasn't caused many problems with customers engines ha ha
V Power may degrade but lets be honest, its not in their tanks long and I certainly know its never in mine long either lol
Just realised, Olly has done a whole days work and NO pictures !!!
I'm concerned for you mate, are you ok ?
no, i feel faint.
just to clear things up, bearing in mind i have a 3 hour journey in the car with you JB, to the mapping session, i think it'll save my ears just to get it mapped on v power ffs lol
you going on would be worse than TBs + SCCR put together lol
Pah, get it mapped on whatever YOU feel right mate ;)
I'll find something else worth nagging at you about, don't you worry.
When were back at mine on friday it will be you doing the nagging whilst I'm doing some uphill gardening
