Here's my latest UOA for my '03 Audi A4 1.8t QMT5. I switched to Motul a while back after being a Red Line user for 7 years.
Quick history;
First oil change was at 10K miles. No UOA unfortunately. Factory fill was said to be Castrol Syntec "German Made" 0W-30. Make up oil was about 2 qts over this time (up until around 6K miles).
Then Red Line 5W-30 was used after that for about 8,000 miles and you can see the the UOA results for that (18,094 miles). Make up was 1 qt. TBN = 1.4
Next OCI was with Red Line 5W-40, but I only used it for 4,211 miles (up until 22,305 miles) because I wanted to switch to Motul. No make up oil. TBN = 3.1
So for this UOA, I used Motul 300V 5W-40 Power (not the new "Double Ester") and went 10,897 miles with it. I didn't plan on this kind of mileage for the 300V series oil, but before I knew it, I was past 30K miles. I'm actually surprised how good it looks. It's considered to be more of a racing oil, but it is applicable for street as well. Maybe just not to be run as long as their other standard car oils. TBN did drop a bit though from 10.9 (according to Motul specs). I also used Motul's Engine Clean at this time, but not with the Motul 300V, but instead with the dealer supplied synthetic oil and OE filter, then dumping it.
NOTE: I use a Canton Mecca 4" Performance Filter which I do not change between OCI's.
For my next 10K miles, I will be using Motul 8100 Ester E-Tech 0W-40. I'm very confident with this product. It carries VW503.01 and many other approvals. I read on a Motul dealers website that VW tested it in a 1.8t for 400 hrs and commented that your next oil change should be in 30,000 km (18K miles!). I'm game
It'll also be interesting to see if anything changes internally after a turbo kit upgrade project I am planning for the car.
I guess I should also mention that I've been doing extended drains for 8 years, averaging 8-12K miles, in VW/Audi 1.8/t's with a combined total of over 225K miles.
