My '98 2.0TDi had a bit less after 95000 miles. I changed the oil for Swepco 70/90 as I had some left over from my Porsche 944 days. Yes, I did check with LR technical who said if you can afford it it 's the dogs.
Well the magnet workswhen I did mine there was what looked like , a smear of rubbing compound on the magnet !
57k ishwhat sort of mileage are we talking?
