we went there 2 days visiting familly, the 95 unleaded was replaced by e10 95 which contains ethanol and is bad for us, so i went with the 98. we made a bunch of videos.
Upon coming back the yellow engine lights came on, it took me a while until i realized it was not supposed to be there.

Only when i arrived home, i red on the forum and in the book it could be the cooling liquid low, so i looked and yes it was low, 1 cm maximum, i added water but the signal engine light was still there, it disappeared only the second time i turned the engine on. since we ve done a good annual service and no faults were found, adding liquid was what was needed.

 

European spec XK/XKR can safely use E10. Here's the relevant section from the 2008MY Driver's Handbook (see section boxed in red):

It's becoming increasingly difficult to find 98 octane in France.

Thanks a lot, a gas station owner said it was bad and i was worry.
Another thing I wanted to add, as the new service manager i dealt with confused em saying the 2010 xkr did not have a gas filter, well indeed it is not where it should be but near the gas tank its different than previous model but there is a gas filter, in case i confused people before. well one jag dealer looked for it 30 mn without finding it, so i thought I will add this.
