dont be frightened about it having to be at a certain temp,
its a LR freelander not a rocket ship
, technology is one thing but dont get sucked into the idea it can only be carried if you have the specilaised equipment .
its common sense, take car for drive to warm up oil, then just park on level ground, undo filler plug first, drain oil out, refill using the small plastic bottles with the clear pipe atached, its quite awkward refilling, make sure you have enough oil ,best to be safe than sorry, fill to the bottom of filling plugg, dont overfill, it helps if the oil is at room temp makes it flow easier, and last thing, take car for a test drive and then recheck levels,
very straight forward job,
