Hi, I've got a Defender 110 300tdi that has missed its regular oil change with regard to elapsed time. Generally, I'd aim to change oil at least once a year, regardless of mileage. This vehicle has hardly been used in recent years and has probably only done 1,000 since its last oil and filter change... but that was proably well over 2 years ago. I would imagine that oil degenerates with time - even when the engine has not been used much. Is that true... if so, is there anything special I should do for its next oil change? Should I put lower viscosity oil in it for the next change? I seem to recall a friend talking about 'special flushing oil'... any ideas on whether this could be a good idea... and what exactly it is?
Thanks
