I've heard a couple of conflicting stories about which oil should be used in the Zetec engine.
Apparantly there is a problem with sticking valves if the oil is too thick (10w40?) but a chance it's not enough protection if too thin (5w30?), although I'm not sure if the sticking valves problem only applies to the older Zetec engine (with DOHC 16v on the rocker cover, as opposed to Zetec
16v on the E).Anyone did an oil change on one and have any info they'd like to share before I buy the wrong oil ? :)
Ta much,
Graham
