2004 Cayenne S with 262k miles and also my 2005 S4 Cab with 202k miles. Keep up with maintenance which I mostly do myself. I always fix small things before they become big ones. And I change oil half the miles the manual calls for. I always have used a synthetic, Mobil 1 to start and Liqui Moly oil after 100k miles because it helps high mileage cars last longer than regular oils.
oil, use LiquiMoly. German oil for German cars.
I did ea888 to 155k. 5k oil changes. Change the damn pcv at like 40k IMO maybe 30k. A bad pcv will give you leaks everywhere so just swap em.
Both of my Guzzis ran better on Valvoline. This is if you’re in USA
I'm using Valvoline 0W-20 Restore and Protect, changing every 4,000 miles. '23 OBW, 56,000 miles. FYI, I did an oil analysis at my last oil change. Wear numbers were excellent, less than 1.5 ppm/1,000 miles. 3 iron, 2 aluminum, 1 copper over 4,128 miles. Fuel dilution was HIGH though, at 4.3%. They expect 1.5- 1.8% for direct injection turbos. According to the Motor Oil Geek, less than 5ppm/1,000 miles is considered good. I do a fair number of short trips, but also some longer runs. I'm going to go to max of 4,000 miles due to the gas dilution.
I’ve used it, no complaints.
One oil that seems to work from all the videos I've watched for cleaning varnish is the Valvoline Restore and Protect.
I use this on my Hyundai Elantra for the past 100k miles ... It's already at 200k and the engine still feels new ... I use Valvoline for everything including power steering ... Valvoline syn blend is a great oil option ...
Got my oil changed about a week again (LiquiMoly 5w40) and now I’m getting this warning saying my oil level is too high.
Liqui Moly is just marketing hype, isn't actually an oil that outperforms other brands.
