Owner reviews for engine oil

In my VN, always Mobil 1 0w-30 AFE.

From wear ratings and certification Amsoil, Pennzoil Ultra Platinum, Mobil 1 (Extended Interval). Amsoil I only use for track days, since I swap the oil out at 3.5-4K.

I had a 2009 Jetta diesel that used a bit of oil until it hit 60000 miles, then it stopped and did not use ANY between the 8000 mile intervals I used.

amazon.ca has Liqui moly TOP TEC 6200 SAE0W-20, VW508 00/509 00. Been using this since day 1 on my 2021 Tiguan with no issue.

I vaguely remember a video or a study done on mobile? Syntec or something, a somewhat scientific study pulling samples every 1k miles and sending out to a lab. Bottom line was that the oil actually got better over miles and they abandoned the project at 15k miles.

Real synthetic oil is way better than regular oil. Even full synthetic oil is better than regular oil. But if you want the best oil for the money look into Amsoil signature series. This oil is a true 100% synthetic oil and will prevent wear and quiet an engine down better than regular oil. I had a lifter tick in my Volvo 850 and it was caused by the pickup tube seal wearing away. I put Amsoil signature series in it and the film strength of the oil was so good it stopped ticking for a year before I had the seal replaced.

After 12 years and 45K miles. I took a 05 Mustang and added a supercharger. For the next three years , and 15K miles, I took it drag racing and high performance track day driving. Wanting more horsepower, I had the engine rebuilt with forged performance parts. When the engine builder measured the wear in the block, everything was still within factory specifications. I had used Amsoil for the life of the car.

I live in a dusty climate I change my oil at least annually and I use Mobil one in my Volvo, Kirkland synthetic in the kids cars, and rotella in my air cooled vw.

I think factory recommendation is Rotella but honestly you can go with any high quality oil. I have used Rotella, Castrol, and Valvoline synthetics in my 500 and I honestly don’t think it matters.

Those guys don't replace you crush washer, and the oil the use is crap.
