Re: Pinking (pre-ignition) 1999 2ltre

I'm on my 3rd tank of either Shell or Texaco petrol now...it's a lot better, but not perfect. If I keep the roof and windows up, it's great!...can't hear anything except all the "good" sounds the engine makes...window down, very faint pinking occasionally. Going to try some octane booster as a last ...

Couldn't wait, had to fill up on the way back from work from a Shell garage ( no Shell, BP or Texaco where I live), still had just under a qtr tank of the old fuel, so a little bit watered down, but it's getting there, the pinking hasn't completely gone yet, but I am confident that on the next fill ...

The only non-supermarket fuel in Tiverton is Esso, and I always use the highest octane petrol available, which I think is 93, so I will have to find either a Shell or Texaco garage (Exeter), and fill it up with 97, that is the only thing I haven't done, as I assumed the ignition would adjust to suit...
