Engine oil Mobil or OEM Audi

Mobil 1 0W40 and Castrol Edge 0W40 Euro. Those are the best oils for our cars in US. The price is excellent too. I run them in all my cars and equipment. Never had a failure.

Oil change every 5K M1 0W-40, zero oil consumption.

According to [these measurements](https://540ratblog.wordpress.com/), Mobil 1 advanced full synthetic (basic Mobil 1) has a film strength of 117,799 psi whereas Pennzoil Platinum's fim strength is only 99,949 psi.

So then **Mobil 1 is better**.

Honestly, as long as you're changing your oil regularly and not putting Autozone branded oil in, it doesn't matter that much. I like Mobile 1 for NA cars.

I did an oil change last week at 5800 miles and used Mobil1 0W40 VW spec .

Truth, Its a much debated topic. Local testing has shown M1 0W40 to hold up the best.

I use 502/505 Mobil-1 0W-40 in my 2012 VW 2.0T, and my 2010 Audi 3.0T. I change every 3000 miles.

Mobil 1 Turbo Diesel Truck 5w40 has a more stout additive package and has lower sulphated ash which means less intake valve buildup

Use good oil, Liqui-Moly 5W-40, or Mobil 1 0W-40 "European Car Formula".

I've used 15w50 Mobil 1 with no problems. It wasn't bad. It acctually good. But, it didn't make one bit difference, so I've used it only once, and went back to the regular 0w40 Mobil 1.
