Thanks very much.First of all it is said on goverment site that Land Rovers from 1996 are safe in regard to E10. 1996 is year when Land Rover were using k-series engines. Looking from that point, and having in mind that there are several talks with ex. Rover employees which confirm that Rover was ahead of its time in order to implement rubbers, pipes seals which are not effected with E10 in any way, anyone should be safe.
Further we have members here which are using E10 or even E85 in their cars for more then seceral years without any problems. These cars are MG F (1997), Rover cabriolet (1994), Rover 25 (2001), Rover 75 (2001). So we have evidence that there are no problems on this topic.
What I would also like to emphasize is that E5 is in use in MG-Rover cars with k-series engines for a long time now and nothing happens. Change from up to 5% ethanol to up to 10 % ethanol will make no difference in regard to destroying pipes, seals, rubbers in MG-Rover cars. I want to say that MG-Rover cars with k-series engines are safe to use with E10.
