Umm, had to fill up with Tesco Momentum 99 octane fuel. But dare I use it on a regular basis, in a 2011 re-mapped 4/4? Seems to have a quantity of ethanol in it compared to Shell V-power. (note: engine pinks on ordinary un-leaded)
I believe all high octane fuels have 5% ethanol in them.
From the Shell UK website:
"....in the UK, Shell regular unleaded and Shell V-Power unleaded are likely to contain some ethanol, but it will not be present at more than 5% (in accordance with current UK specification requirements)"I use Tesco 99 in the Morgan and the AMG.
No issues.
