Engine oil Mobil or PENNZOIL

I've always had great luck running 0w-20 Mobil 1 through my 2012 skyactiv. Regular changes through 130k and counting.

I use Mobil 1 full synthetic on my track prepped 350Z

Toyota Synthetic is made by Mobil. It’s basically Mobil 1.

Prior to switching to this I ran Mobil Delvac 15w40 Dino for 100 k miles. LOA is identical both oils. I have run Delvac in DEtroits, Cats, and Volvo’s.

Mobil 1 Synthetic. im at 291k mi. no internal engine repairs. drive i hard every day. i change about every 6k mi. along with factory filter.

Even though Amsoil produced the lowest wear numbers I'm using ultra platinum since I find that is what my car runs best on, engine is quieter than with amsoil or Mobil and velvety smooth.

Mobil 1 0w40 why? its the cheapest 502 rated oil I can find.

In our 2003 1.8T Passat, we use; Pennzoil Platinum Full Synthetic High Mileage 5w-30. Changed every 4000 miles. Because we made the change early, we have not had and engine oil sludge problem. The Passat now has 205k miles.

I have a 2014 Audi A5 2.0T owned new since July 2014 and have done about half of the oil changes the car has had, myself. I have 61,000 miles now and the engine remains completely healthy as far as I know, with negligible oil consumption. My car has an electronic display virtual dipstick, not a physical one, and it takes several thousand miles before the oil level dips below "max" by "one notch" on the gauge picture. This type of Mobil 1 is 0W-40, which does meet VW 502. I never was able to tell any difference in feel or economy between the 2 weights of oil even though the Mobil supposedly should be a bit thinner at cold temperatures.

I've used Mobil 1 since 1986 in my other vehicles, but I don't want any issues with VW should there be an engine failure. Once out of warranty, I can buy the same oil for less at Walmart.
