I have a couple of Tesco's nearby and now I have a new motor I want to start running this on better fuel as it's a bit more performance oriented than my last cars.

My most local Shell has stopped doing V-Power. There is one about 10 miles away which is ok in terms of price or one about 7 miles away which is not very cheap.

Local BP garages either don't have their fancy stuff (forgot it's name) or are a COMPLETE rip off.

I've put 20 quid of Tesco Momentum 99 in (only had it a couple of weeks and have just used Shell 95 ron so far) and I am just pootling around with it at the moment but I did give it a squeeze this morning and it picked its feet up from not many revs in 2nd and decided to go tyre smoking down the road. Kinda surprised...

Having read a little, most Civic Type R owners rate higher octane stuff but I trust the OcUK motors massives opinion on stuff like fuel.

Simply, is it any good, or is it the typical "avoid it, it's from a supermarket" kinda fuel. I've always ran Shell 95 ron or Jet 95 ron in most cars I've had, they've all liked both of those fuels, but I'd like to treat the Civic a little better with it being able to rev to nearly 9000RPM!

Ta :)
 
The arguments with the standard 95 supermarket stuff that gets brought backup to standards with hocus pocus - the 99 stuff is fine, but V-Power will always give extra internet horses.
 
Problem with high octane fuel from supermarkets or even from shell is that it sits in the tanks a lot longer than the standard stuff as not that many people buy it.

With our turbo metro we actually find that it runs better (and was easier to tune) using standard 95 octane fuel (esso for the record) and octane booster rather then tesco stuff.
 
But a turbo metro has an A series, hardly the height of modern engine tech or something that would take to higher octane fuels as well I'd suggest?
 
I've used it for sometime and found it fine. I'm not going to say I've noticed a difference over 95 or seen any difference between it and Shell or BP, but its more of a case that its only a few quid more per month for me, the handbook says 98+ ron recommended and it has the cleaning stuff in.
 
The manual for my Leon Cupra recommends 98+, my Swift Sport the same, but my CTR 95+, and it's been run on 95 since I've had it. It's not meant tot make a blind bit of difference with the CTR when you use higher octane fuels. Actually, I tried some a few tanks back, and no - it made no discernible difference.

Far from standard. Last dyno session was at 17psi and made 174bhp. Recently been running 25psi with it and making 13.9's @ 105mph with **** poor 60ft's.
 
If you change fuels to higher octane after running 95 for an extended period, you will likely need an ecu reset to notice any difference.

The Ecu has learned that your fuel cannot cope with high levels of ignition advance, so has retarded your ignition. A reset will set it to learn again, and the new fuel will allow more advance.

This doesn't work on all cars :)
 
I think I'll see how it goes on the Tesco stuff. I often have 5p off fuel vouchers too which will come in handy. My Golf 1.8 20vt I had before was mapped for 95ron fuel (stage one APR map) and it ran like junk on 98+ stuff. My Corsa 1.6 16v beast before that was no different on either cheapo shell or vpower.

We need to see more of this Metro. That sounds quality! :D

No - higher RON fuels are not picked up by the ECU, it is the engine knock sensor that manages this seamlessly.
