Put some proper oil in both though. Should be fine after that. Unless you are running big power, in which case more regular changes are probably a good idea.
Ok thanks. Both has been changed for the proper stuff but 1st gear is occasionally difficult to get into and the diff has 'clunked' for the second time since owning it (6 months).
Might just change it as a precaution at the next service.
Hello Simon, Monkfish changed the oil in the Diff and gearbox during my ownership at around 15k. The diff may just need another dribble of modifier. Andy
Hi mate - yeah I did notice you did that, maybe it does just need a top up !
