Engine oil Castrol or OEM Audi

Castrol edge is just fine, even the cheapest one is likely better than whatever was good 20 years ago.

I have an 2007 A4 2.0T base. I bought the car with 120k miles on it in 02/19. Yesterday I hit the 224k miles on it. She's my daily driver, over the years I have changed/did the engine oil every 4k miles, car filters all over, wheel alignment, tires, brake pads, rotors, and the battery. Nock on the wood, my baby have been taking car of me. I'm actually surprised that this model is solid af.

295,000 miles using Castrol GTX high mileage and fram XG filter

Michigan I use 0w20 Castrol Edge all year.

As long as you're not getting cheap gas station brand oil, you'll be fine. I've been using Castrol Edge 5w40.

Mate, just get Castrol Magnatec 5w30 full synthetic and change it every 8000km or 1 year, don't fall for snake oil propoganda

I use Castrol EDGE 5W-30 LL Fully Synthetic Engine Oil on my B48 pre LCI G21 no issues at all and complies with BMW specifications

I have a 2010 Jetta TDI cup edition with the CJAA engine and the factory spec listed in the manual is 5W-40… On top of that the oil cap alone has Castrol on it\nSo Castrol 5W-40…. End of story…. I apologize if I sound condescending as I do not mean to and also recognize you may have purchased your vehicle second hand and it may have not come with a manual… But if the top of your 710 aka oil cap says Castrol on it and you truly have a CJAA engine then I guarantee you that Castrol 5W-40 is the proper oil regardless of location or climate Ps…. Anyone who claims to use or recommend anything else has also probably had massive engine problems or engine repairs an question why they had those issues Follow factory spec and maintenance recommendations…. I’m pushing 280k on my CJAA engine without a single issue

Daca e motor de la VW atunci recomandarile mele ar fi Liquimoly Longlife III, Motul 8100 X-Clean+, Mobil 1 ESP.

Reprezentantele folosesc in general Castrol Edge LL. Dar eu nu prea sunt impacat cu brand-ul asta.

I tried Castrol and was not a fan, found it burned faster than any oil I used.
