Big problem with getting fuel for my WRX STi today, none in Newton Stewart (Shell), tried Girvan Esso, on to Tesco in Ayr on the last vapours, success - 50 miles after the fuel light came on! Anybody else having this issue? More if a problem in rural Scotland where there is less choice.

I've heard of issues with E5 supply in various areas, but I fuelled up on Monday at our local Sainsbury's and both E5 pumps were on.

Thanks. So, patchy supply, which has been reported in a thread from England since April. Wonder what the cause is.

Grangemouth refinery closing? This is bound to have an effect on the supply chain for petrol.
No Tesco Momentum where I am - also because it is so cheap.

99 comes out Clydebank as Grangemouth only does 97 so supply for that hasn’t changed at all.

Clydebank supplies Tesco UK? There are E5 shortages all over the UK.
Shell seems to be okay though - at least here.

Out of curiosity, what are your issues with E5 / 97-98 RON or E10 / 95 RON?

Pinking due to lower octane rating or concerns over ethanol content? As both are correctable.

The Monaro, since it had a Wortec remap way back in 2005 or 2006, pinks on 95 RON under load. Here in Orkney, thats all you can get. So it gets a bottle of octane booster on every tank, and problem solved, no more pinking. If on mainland Scotland, if it gets the luxury of 97/98 RON, then no octane booster required.

As for ethanol content, then this is easily stripped out if of concern. Nothing more than some water and a settling container needed. If you are being posh, some liquid food colouring to highlight whats water and whats petrol. I routinely strip E10 down to E0 (pure petrol) for storage fuel for lawnmowers, bikes and cars. Add a little fuel inhibitor and a bit of octane booster (to compensate for the boost the ethanol gives) and you have a pretty passable pure petrol.

Some kitchen chemistry and you can easily manipulate pump petrol to where you want it to be. Just don't let the missus catch you doing it in the kitchen sink! rofl

No offence, but that sounds a bit of a faff for 120 litres hehe much less hassle to just chuck in E5

True, but has a couple of pre-requsites;

1. You can readily lay your hands on E5, which in many parts of Scotland, you can't. And from the OP, even the deep south seemed to be having supply issues with it.
2. You are happy with E5 and not E0 for your storage / running fuel. There's only 5% ethanol content difference between E5 and E10 (No sh!t Sherlock! biglaugh) and if getting rid of the ethanol is the goal, then the job is only half done moving to E5

apparently, whilst not advertised as such, Tesco Momentum is E0.

Apparently so indeed!

Another kitchen chemist testing some about 3 weeks ago, and 0% ethanol. Unfortunately, not something we get here in Orkney. Adding the water to strip out the ethanol results in a fair gain to the water volume, indicating a fair ethanol content. All we have here is one product that comes into Highland Fuels who were historically Esso, but don't seem to claim any allegiance any more. The same fuel is drawn out of the same storage tanks and distributed to all filling stations, most of which appear to be unbranded these days - i.e. they do not display if they are selling BP or Esso which used to be the 2 distributors here. So could be anything here, and certainly has a fair ethanol content.
