I find the V-Power is good in theRover Plus8. The EM light used to come on when using 95 octane. Using 97 from Shell/BP couple of others means no light comes on. I did use Murco 97 a couple of weeks ago and the light came on. Same “random intermittent misfire” fault as usual.
No tests on ethanol content done so can’t comment exclusively on any effects.
My concerns over ethanol are for perished rubber seals in the fuel system. I THINK my car is new enough to have resistant seals. No worries about water absorbtion as the petrol is never in the tank for long enough
