We have a Fiesta 1.25 Zetec, with 23K miles on the clock. For the last 6 weeks we have only used the car locally, but very stangely ( I think) the deposits in the exhaust tail pipe are a very light grey. The has only recently occurred and in all other respects everything is normal. Going back 2O years I Would have considered this a sign of a very weak mixture-Has anyone any ideas/comments?
Thanks

What colour are the deposits normally?
Going back 20 years we had lead in petrol, lots more sulphur too, and no catalytic converters or electronic engine management systems. At least, not on Ford Fiestas.

The grey colour, IIRC, was from the lead.
Has it been run on different fuel to usual?

My 2001 1.6 Fiesta is the same... nice and gray. Looks normal to me.. (efi actually works!)
