Castrol 0W-40 or Mobil 0W-40. Take your pick. As for filters, Ive always preferred Mann. Both of those oils are available at Walmart in 5 quart jugs at a good price.

I had later version of that engine, Castrol 0W30 or now 0W40 worked smoothest. M1 0W40 (granted, at that time was older version) was bit noisy.
Still, both Castrol and Mobil1 will do good. More important is that you use in that engine large oil filter. There are two types, smaller one and large one. Under any circumstances do not use smaller one since larger is one of the ways to address sludge issues those engines had.

For oil use any xw40 that meets A3/B4 or 502/505 and for a filter you want a mann w940/44 or a Mahle oc51.

Rotella can go a lot further than a 940/25. They updated it for long life and called it a 940/44 which would better utilise the abilities of the Rotella

I wouldn't recommend that. Those engines needed full synthetic to prevent sludging.

Use the big diesel filter that was part of the bulletin and any quality synthetic. I did run semi syn 15/40 in mine for about 10k, but this was for short intervals under 5k after I had to replace the head. Timing belt stripped at 57k, back in 2001.

out of warranty a 10W30 fake synthetic will do fine + a quality filter. if you don't mind the cost a real synthetic is best but that worked well for my 200,000 mile 2001 1.8T jetta aka cheap audi. if your consuming a 10-40 or 15-40 would serve better. i am above you in Pa just a little cooler + 10W works well, my 2001 TT gets the 40 variety as it uses a bit more than the similar jetta engine, both hopped up!!!!

Full synthetic 0w-40 and the larger filter. I would use the M1 annual protection and change at the manufacturers OCI.

No. First off there is no 0W-40 Annual Protection product. And second, I would not use the AP due to the fact that the highest HTHS available (5W-30) is 3.0 which is lower than what Audi requires with 502 00 oils. The ExxonMobil site recommends 0W-40 FS or he can use Castrol 0W-40, whichever one is cheaper. Do not use the Annual Protection product as it is neither recommended by ExxonMobil for that engine nor does it have the proper characteristics.
