Engine oil LIQUI MOLY or PETRONAS
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.
The recommended Castrol isn't bad, but I've had better success with Mobil1 and Liquid Moly.
Try using liqui moli engine oil, change the air filter too.
After completing the 1000 km run in and going through the first service where I got Cepsa xtar 10w40 oil, the gearbox remained hard, compared to my previous F650 bmw.
Did some digging regarding engine oil and how I could improve my gear shifting experience, engine smoothness and durability and the choice was either Motul 7100 or LiquiMoly Street Race 10w40. Decided on Liqui Molly and definitely I am noticing much smoother gear shifts and maybe even less vibration. I am surprised. The change is definitely noticeable.
5w40 liquidmoly
Imo Mobil 1 is mid grade at best. Liqui-moly is the only thing I’ve used for the last 5 years, I too started with Mobil 1, then switched to liquimoly (same weight) and the engine was immediately quieter, smoother, and ran cooler.
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.
