Tesco 99 is cheaper than BP Ultimate and TVR loves it.. extra pops and bangs on the over run :)

Fuel wise I use Tesco 99 Octane and found it works very well in both our Astra and Corsa VXR’s, not a fan of BP, power feels a little flat, V Power feels exactly the same in both cars compared with the T99 but being that bit cheaper, T99 wins me over.

I use a mixture of either Shell V Power or Tesco 99 Octane. Tesco's is kinder to the wallet right now though! www.mtorque.co.uk 9/12/08

I always feel the engine is performing better after Tesco 99 Octane.

I have been using Tesco 99 Super Unleaded in my standard 1.8 Sri estate for some time now and I find it gives my car more pull and smoother acceleration. I've found that Tesco performs better than Shell.

All the Tesco stores in my area have it (Tesco 99 Octane), my car loves it and rewards me with added pops and bangs that are better than BP Ultimate.

My RS6 runs considerably better on Tesco 99 Octane than just about anything else… As does my 1.8 V5 Passatt!

I only use Tesco 99 or Shell V Power. I believe with a higher rating fuel it will burn more efficiently, less wear and tear on the engine and possibility of more mpg.

She (my car) does like Tesco 99 as I do feel a difference with that one… and I get a few more MPG too.

I’ve noticed the mpg increase on Tesco 99 Ron! Car feels much smoother with that.

My car gets 30mpg on Tesco 99 Octane compared to 25-27mpg on 95 ron (standard fuel). It also runs smoother, picks up sharper etc
