Engine oil Mobil or FUCHS

VW recommend full synthetic 5W-30 or 5W-40. Some owners also use 0W-40 as well, it's easier to find on store shelves. Honestly using the right type of oil and changing it regularly is more important than the brand. Just don't buy the cheap store-brand recycled stuff and you'll be fine. People go back and forth online about brands and stuff but you're probably talking about fractions of a percent better one way or the other. If you still want suggestions: Mobil-1 oil and a Mann filter, there, I said it.

Full synthetic 5w-40 if you can find it, you could run 5w-30 if not. The 1.8t needs around 4.8 qts I believe, so just buy 5 so you have a little left over. Mobil 1 is my go-to oil.

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.

My 15 S4 has seen 3 oils in <10k miles. The factory fill was Fuchs. Dealer first change was PP Euro and my latest change the other week was with M1. I've run M1 0w40 Euro in my B5 forever and have had 0 issues with it. Saw no reason to not continue running it in the B8.

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 .

Dark oil is actually a good thing believe it or not. It means that the oil is doing it's job and holding all the contaminants in suspension. In fact if my oil would look clear at the oil change I'd be very concerned and most probably change the brand.

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