Just got back from 2000 mile trip around France and had problem with fuel.
Stuck to 98 RON but picked up a low rev misfire after filling at a rural station.
It eventually cleared on main road refills but got caught again at a Total station.
The best seemed to be the new supermarkets which had queues to the pumps.
Wondering if the small stations are having the turnover, especially in the 98 fuel.
Our local station stopped selling 98 because of low turnover.
