Engine oil Mobil or FUCHS

I use 40 until Winter then I switch to 30.

I use OEM oil filters and Mobil 1 15w50 oil on my oil burning autobahn buster Scirocco

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.

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

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.

Recently got my first oil change at 5K and used mobil 1 0w40. The engine is now louder as compared to what it originally was. Not sure if it is the oil being too thin? or perhaps the cold weather.
