Sorry, I'm being a wee bit forgetful/lazy - car due for a service in a couple of thousand miles, and could do with a bit of a top up before the long trip to Mackies tomorrow morning for its gearbox service.
Could some kind soul please remind which engine (
NOT gearbox) oil I should be putting in it - I've got loads on choice in my garage (for various cars...), but can't recall which one is for the S8
.
