Engine oil Castrol or VALVOLINE

If you do research oil analysts here in this sub, Valvoline comes out the best.

Using high mileage oil (additives to make gaskets swell just a tad bit), used to burn almost a quart between 5k miles but now it's maybe half a quart.

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

Looks real good. Valvoline R&P is in mine now.

Valvoline Restore & Protect oil, stat!

I do like Valvoline R&P and it is in fact cleaning up two older, normally aspirated cars I have with oiling and ring issues, installed in one Lexus and one older Acura (Isuzu).

Oil burning around 150k, although switching to Valvoline Restore & Protect I've basically eliminated it. Seems to be related to carbon buildup in the low tension rings.

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

For example my previous BMW engine was very noisy with mobile 1, and quiet with castrol

Forget Castrol LL! Its a VAG Killer Oil. In this Case Mobil 1
