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
