This car was maintained by a previous owner. I think it was 5000 miles, but it may have been 10,000 per the manual. He didn't tell me. The engine had faulty glow plugs, which were replaced by VW about 2000 miles before the oil sample.

TECHNICIAN: "Iron and copper are high compared to universal averages, which show typical wear after about
7,100 miles on the oil. Iron is from steel and copper comes from brass/bronze. Other metals are fine and no
contamination was present that might account for the wear. The viscosity was a bit thick, but that's probably
not the reason for the excess metals either. If engine work has been done recently, it could explain the iron
and copper. The TBN shows plenty of additive remaining, while the TAN of 7.9 shows some acidity. Check
back and we'll see how wear metals trend."
