hey guys,

in my C200 1995, I used to run 96RON grade petrol. But lately I have discovered something.

If I use 91RON grade petrol, it performs better. An in addition with 96 I get a rotten egg smell from the cats, and a "lul" when first accelerating when cold.

With 91 these two arent present

why?!
