Hi
I would stick with the 5w30 as it what jaguar recommends and the 10w40 and 20w50 might be too thick in winter
also I thought the oil has to be 5w30 A5, as that's the one that meets jaguar WSS-M2C913-B , C3 does not meet the jaguar spec
cheers

Hi Paul
I might have a go as well once the pics are back up
all ready got a touch screen ready to operate on
may be we should start a new topic when we start with plenty of pics
cheers
Joe
