Just a quick one, in the past when I have had turbo'd cars being they were quite highly modded I always ran them on super unleaded. Does the mk1 octy vRS require the same or do you run them on standard fuel???

Stick to Shell's finest, V-power all the way.

 

Mine runs better, gets better consumption and feels more responsive all round, compared to running super market super U/L (Tesco 99 etc).

 

I'm running a stage 2 re-map (conservative 225bhp), drives like a standard car and still returns 40+ mpg on a run.

I did a load of testing on various fuels - thread is in general motoring somewhere. You don't *have* to use super in the Octy, she'll take 95ron fine. However, you will get a subjective performance improvement and your MPG will be better on super. I did some calcs that over 10,000 miles you're better off with shell v-power than any other as the improvements mean it works out cheaper than running tesco 95 standard over the same period.

I've ran mine on tesco 99ron for a fair while now. My car loves the stuff. My wife used the car for the day a bit back and put some esso 95ron in and I could tell as soon as I got in it. I havnt calculated mpg though.

Mine has been mapped on Tesco Momentum 99 RON, so that is what I use. It makes sense to run both the Skoda and the track car on the same unleaded, although I have found out that Tesco fuel pumps stop at 100 litres.

 

I must have a lead foot as I don't get more than 35-37 (genuine) mpg on a run now and 25 mpg with 1 tonne of Caterham, trailer, fuel, wheels, tyres and kit hanging off the back. The on-board computer tells me that I can do over 47 mpg with steady driving, but bigger injectors have knocked this out of kilter.

 

But I didn't buy a "performance" car to worry about fuel economy, so I just drive it and forget about running costs.

I have to echo the above comments.

 

Mine is running a very light tune - Stage 1 Revo remap, PiperX filter, Forge DV, stainless exhaust.

 

Runs as sweetly as a kitten on Shell V-Power. Hyper-responsive, no flat spots, buries itself into the breadline as willingly as a tramp buries himself into a bag of hot chips...Also the added bonus is, as said, all this with the best MPG returns.

 

She runs like a sack of **** on anything else - it's really noticeable. Even on so-called 'performance' octanes (i.e. BP / Esso / whatever's Super Unleaded). On these fuels, which I sometimes have to get depending upon where I am, the car hates it. She won't build up any boost - I suppose because the engine detects pre-ignition and immediately dumps the boost and retards the ignition. Terrible. It's like driving a different car.

 

The only exception is Tesco Momentum. This is a reasonable alternative - but only in some driving conditions. It works pretty well if the outside air temperature is quite cool - if it's a warm day, or if I'm on a run and the intercooler and pipework has got hot - then Momentum also causes a loss of power.

 

Shell runs great ALL of the time.

 

So with all these benefits, plus the fact that they sell it as being kind to your engine / keeping it all clean inside - then there is surely only one choice?!

I've been running Tesco momentum on everything performance car I've had in the last 5-6 years.

Someone compared the momentum and v-power, and Tesco came out the winner.

Cheers guys. It will be momentum99 from now on in then, mainly as I work next to tesco

When I was doing testing earlier this year I found the opposite - Momentum gave worse MPG than V-Power and the lower cost still didn't offset it enough to make it better than V-Power.

 

Checking back on my original thread I was still looking at BP fuels vs Supermarket rather than anything else and never got round to updating it, however I repeated a similar test with Tesco normal vs Tesco Momentum vs Shell V-Power and out of those three and the original testing, V-Power was way ahead of anything else in VFM and MPG.

Also note very interesting comment from andy68 in post#26 - again not the most scientific test in the world but same set of rollers, gains of about 15hp and 30 lb/ft from V-Power over Momentum.

I have to agree. The few tanks of v power I've used I wasnt too impressed with how the car ran. I've had no performance issues with momentum and it is quite a bit cheaper.
