What fuel do you use in your classic

I too use Tesco Momentum, but now realise the error of my ways.
I could be driving a 360 BHP supercar.
I usually use the same Shell garage locally, more due to habit than anything else. Anyway, my car developed a significant flat spot and began to stutter and misfire throughout the rev range. Whist stationary I could rev the engine and clear it but, as soon as the engine was under load, the misfire / flat spot would return. We spent the next few days changing everything in the ignition system and all relevant sensors. We checked fuel pressure, then replaced the pump ''just in case''. New, plugs, leads, dizzy cap, rotor arm, fuel filter, pump etc. The list was long and bloody expensive! Nothing we did made a bit of difference and I started questioning whether the ECU map could have somehow been corrupted? My E30 M3 runs a piggy back ECU and Alpha N which is known to be sensitive. It was at this point someone questioned what fuel I was running and I remembered diving into Tesco when my reserve light had come on. I had not had a problem with supermarket fuel before and didn't really consider it likely, but we drained the tank and refuelled with V power. A quick run around the block and normal service was resumed.I could be driving a 360 BHP supercar.
I realise that a large number of people use supermarket fuel in their cars with no problem. All I know is that my old E30 isn't one of them.

Does it have knock sensors? Have you tried it on other 95? I'm thinking it sounds like an octane issue rather than a source one.I realise that a large number of people use supermarket fuel in their cars with no problem. All I know is that my old E30 isn't one of them.
You can actually get 'proper' four star from a few Gummint approved outlets, but it's eye-wateringly expensive!
Mine comes from Ganderton's in Buckingham. Here's a link to the complete list of outlets:

Yes and it may well be that it's actually more than 98 RON! Certainly when the change over happened one of the approved fuel suppliers was selling what amounted to five-star.Mine comes from Ganderton's in Buckingham. Here's a link to the complete list of outlets:

There seem to be a lot of outlets in that list until you think through trying to run on that fuel only - unless you have a really large fuel tank of course.

The FBHVC lists 13 Four Star outlets but I suspect even that list is way out of date:

I also run a big old lazy (and sometimes not so lazy) V8 and was advised to use Shell Nitro or BP Ultimate.
I also empty in a bottle of ethanol reducer or ethanol protector to stop the fuel lines and internals from degrading. This was also recommended by the specialist I use for servicing.
