This is my 2nd analysis on this car. '09 Jetta TDI 6M w/ 114K. Car has been mechanically sound, however it has some electrical/sensor issues that appeared at ~100K miles so I think it's time do the buyback while I still can.
1st sample was about 5 years ago and it posted here as well. https://www.bobistheoilguy.com/forums/ub..._42#Post4621345
70% freeway, 30% city
I added about 200 mL of LM 2009 Mos2 to this oil. Ran the car exclusively on HVO w/ Stanadyne PF additive for about 4K miles. We Californians have limited access to HVO.
Iron PPM is similar per 1K than the previous test.
TBN is low like my previous sample. I think if I had gone to 10k it would have been < 1.0 again. This oil does not hold up.
Do these cars have lead/copper bearings or are they the aluminum type?
