Engine oil Castrol or OEM BMW

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

Done 2 oil changes so far and car has not used a drop of oil and I drive it pretty hard.

I’ve used Castrol and Castrol High Mileage on my Mk6. At just over 143K miles, I’ve had no engine issues at all.

Been running Castrol in my VWs for 20 years. Never had any issues.

Nah you're fine. BMW engines are known for using some oil. Even 1l on 5k km is not much, even the dealership considers this as normal.

One time I had the oil bug bite (keera) and I decided to get the best oil. Castrol (I don't remember the number) but it was 340 AED for a gallon. I poured it into the engine and it felt good. That weekend took it for a desert drive and during one of the breaks, the entire oil just leaked out of the main seal. The oil was so good that the engine didn't have the tolerances to hold it back.
