MAKE/MODEL: Audi 1.8L Turbo OIL TYPE & GRADE: Brad Penn 20W/50 FUEL TYPE: Gasoline (Unleaded) OIL USE INTERVAL: 9,500 Miles ADDITIONAL INFO: UNIT PHONE: FAX: ALT PHONE: EMAIL: CLIENT You said you were interested in a full 10,000 miles on the oil -- go ahead. You're almost there with this sample and everything looks great. If everything goes okay over the extra 500 miles on the oil, you'll maybe see a little more iron, bL everything else should hold quite steady. No contamination turned up here, and it looks like the TBN is up to the 10,000mile challenge, as it's still reading 3.7, showing plenty of active additive lelt. This oil seems to work well for this engine. See you at 159,000 miles. You could even try 11,000 miles on the oil, if you want.
