I've been for some petrol at sainsburys this morning, & i noticed that all the pumps now appear to be E10 petrol only. So i put juat £10 worth in to see how it goes, mine is the 1.8 volvo engine so should be ok, but i will still be using the old E5 where i can get it

Non-GDI engines should run ok on the new E10 fuel. As for the GDI models, I'd run them on super unleaded if possible.

Saw something similar, when a mate of mine decided to start running his old diesel transit on used chip oil, it then kept springing one leak after another & eventually ended up having his diesel pump rebuilt ! |

My 850 TDI has been ran on veg oil prior to my ownership, and it's possible that the pump needs doing on it at some stage. My 1999 LDV Convoy recovery truck with the 2.5D Ford engine possibly has in the past as well, as it has been a challenge to get it running well in the near-zero years I've owned it.

They should all "run" just fine on it.
The danger lays in the damage it can cause to certain materials in the fuel system, usually synthetic ubbers and plastics, over a period of time. Fuel pumps and injectors are the main vulnerable components, followed by sensors and pipework/hoses. Up until components start to degrade all cars that run ok on 95 RON will run fine on E10. If components are tolerant then a car will run happly on it ad infinitum.

The GDI just about runs on 95 RON, which anyway eventually clogs up with carbon deposits and coking up everywhere, making it run like a dog. 98 RON is the only option for GDIs out there. Not that there are that many left out there anyway

The RON is a measure of a fuels compressibility before it spontaneously ignites, or "knocks", and nothing more.
97/8 is not more energetic than 95, and when burned does not produce any more or less carbon. The GDi is a fairly high compresion unit for a petrol engine and may well run happoest on 97, but when on 95 if the fuel does not burn properly for reasons of preignition the by-product of that is unburned fuel, not more carbon.
