MAKE/MODEL: Audi 1.8L Turbo OIL TYPE & GRADE: Royal Purple 5W/30 Z FUEL TYPE: Gasoline (Unleaded) OIL USE INTERVAL: 9,500 Miles 3 ADDITIONAL INFO: PHONE: E FAX: .4 ALT PHONE: d EMAIL: U) WILL: Copper is looking a bit better, and there's no fuel this time around, but those are really the only improvements we 5 have to report for your Audi. If iron was from wear-in, it should have decreased on this oil run, as would silicon. Instead, UJ both ofthose elements increased on a similar oil run, and aluminum is up into the highlight range as well. Did you nd E any air ltration problems since the last sample? Aluminum and iron suggest pistons/cylinder wear -- piston scuffing o perhaps? The TBN was 0.0. Maybe cut down to about 7,000 or 8,000 miles next oil and check back then. 0 MI/HR on Oil MI/HR on Unit 139 600 125 000 8a e Date 03/05/14 09/23/13 Make U Oil Added ALUMINUM CHROMIUM 1 1 1 1 IRON 9 6 3 16 COPPER 2 4 6 7 LEAD 2 3 4 3 TIN 1 1 0 1 MOLYBDENUM 2 0 8 46 NICKEL 1 1 1 1 MANGANESE 1 1 1 2 SILVER 0 0 O 0 TITANIUM 0 0 O 0 POTASSIUM 5 5 4 2 BORON 3 3 3 SILICON 21 17 SODIUM 117 156 CALCIUM 3123 MAGNESIUM 12 PHOSPHORUS 1099 ZINC 1248 BARIUM 0 Values Should Be* SUS 210F 54-61 cSt 100C 8.5-10.8 Flash int in F >365 Fuel % <2.0 Antifreeze % Water % Insolubles % TBN TAN ISO Code * THIS COLUMN APPLIES ONLY TO THE CURRENT SAMPLE 416 E.
