Finally got my A4 2007 with 29k analysis back using GC for 5k looks pretty good, I think I'll stay with it ROBERT: Thanks for the note. We did indeed find quite a bit of fuel in this sample, but who knows how much would have been present if you hadn't started the engine first. Maybe just a little, from driving around and idling on cold mornings, or maybe none at all. You can always try taking a sample stone cold next time, to see if the data changes. Wear looks really good. Universal averages show typical metals from this type Audi after 5500 miles on the oil. You can go longer than 5000 miles. The TBN is still good at 5.5, try 7500 next time ALUMINUM 3 CHROMIUM 1 IRON 22 COPPER 4 LEAD 1 TIN 0 MOLYBDENUM 17 NICKEL 0 MANGANESE 2 SILVER 0 TITANIUM 0 POTASSIUM 5 BORON 25 SILICON 5 SODIUM 4 CALCIUM 1662 MAGNESIUM 402 PHOSPHORUS 852 ZINC 996 Sus vis @210F 6.1 cST [email protected] 10.54 Flashpoint 330 Fuel 2.8 Antifreeze 0 Water 0 Insolubles 0.3 TBN 5.5

This oil is STOUT! Even with the turbo, it looks as though it could still handle 10k easily! I'd keep using it if I were you!

Even tripled iron would be below 100PPM-perfectly normal.
