I've always used Elf oil for my Renaults. I had my 200 serviced a few days ago and I used the latest Elf Evolution SXR900 5w-40. It's amazing how much of a difference an oil change can do for this car (as well as general servicing). The engine seems a lot more responsive and the typical stutter at 2k rpm at high gears & low throttle is pretty much gone.
