Stumped for ideas!

So I thought this would do. A typical Friday with a journey to town to get some bits for the LR service and was somewhat surprised to be gaily informed by the service department that they no longer stock 10/40 oil for the defender as there is no demand....! Excuse me......! He then went on to say that as they charge £100per hour +VAT that most defender owners don't use them......I'm not surprised! So back to Alan to get the high spec oil that is probably better then LR's anyway!
Perhaps I'll have the energy to do the oil change tomorrow as well as dropping the sump to reseal as it does have a minor leak on the joint.
