Dal,
Thanks for the mail.
I would not really worry about the nikasil/synthetic issue as really, its not an issue. Synthetic is a broad word and many synthetics sold on the market are still 100% mineral base albeit very highly refined (including fords new synthetic). So without knowing what synthetic allegedly can cause these issues and what about the synthetic that can cause the damage then the general belief that synthetic is a bad idea, is miss leading...
I do not see any reason why a good quality syntnetic 5w-30 would cause any harm in the 1.7 Zetec, we have recommended and supplied synthetics to these for many years, especially modified track go'ers and competition cars.
Regards
Guy.
