Miles on car 250,892 , miles on oil 19,749 miles
Total oil used was 5 Liters of Red Line 5W20 and 40 oz of Z-MAX as make-up oil. One VW full flow filter and a used Amsoil BE-90 with 41K miles were used.
First column is UOA of Red Line 5W20, second column is UOA of the previous 41K using Liqui Moly 5W30 and Red Line 30WT race oil. All UOAs were done by Polaris lab.

IR Nitration..... 21.............21
The Oxidation number is due to the Red Line oil. I posted the previous UOA because I did not replace the bypass filter (Amsoil BE-90) previously which contained about a quart of the old oil. I used Z-Max as makeup oil because it gave me better mileage and also less oil consumption.
This 20K run included a full Arizona Summer and a 3,700 mile trip from Phoenix-Oklahoma-Minneapolis and back during Christmas. I always add about 8oz of 2T oil per fill up and it is usually Phillip-66 InjexPro or Mark III castor oil, whatever I have left on the shelf.
I replaced all filters and is currently running 0w5 Neo Racing Synthetic. This oil makes my engine so quiet at idle and at speed that I was totally surprised. Based on my Scan Guage read out my mileage went from 62.5 (with Red Line 5W20) to 63.7 at 50mph. I got about 1,200 miles on this oil and so far so good.
