Miles on car 231,143, miles on oil 41,023 miles
Total oil used is 7 Liters of LiquiMoly Longtime Hightech 5W30 and 2 quarts of Redline 30WT race oil and 8oz of Z-MAX. One VW full flow filter and an Amsoil BE-90 were used.
First column is UOA at 20K, second column is UOA at 41K. All UOAs were done by Polaris lab.

Zinc............ ..1424......1382
Fuel............. 0.7%...........0.5%
Soot............. 0.1%...........0.2%
Water (IR)...... < 0.1..........< 0.1%
VIS @ 100C ..... 11.9 cSt......11.7
TBN.............. 7.39...........2.48
IR Oxidation.... 51.............53
IR Nitration..... 17.............21
The Oxidation number is due to the Red Line oil.
I refilled the car with Red Line 5W20 and replaced the full flow filter but did not replace the BE-90 since it still has very good output. I replaced the air filter but not the fuel filter.
