Well since Covid arrived I've only done 3000kms since taking delivery of the car. The noise at cold start is really terrible but I can't fault performance, economy and nor has code been set. As such I think its a characteristic of the engine. The ford service manager for my dealer actually visited to experience the fault first hand and I'm overdue taking the car in for them to review.
I don't think it's a fuel issue. Our sulphur content in 91 isn't great at up to 150ppm allowable but I think 95 and up are competitive with other regions.
Anyway. Great car for the money. I'm living with the noise on cold start and enjoying the performance once warm!
