Engine oil LIQUI MOLY or Castrol

I use Liqui-Moly Spec Tec 5w-30 in my ‘99 328i with 330k km on the clock, runs like a top

The OEM oil filter worked well to keep insolubles low, and after 8,570 miles on this fill of Castrol High Mileage, the 2.8 TBN shows the oil had active additive to spare.

Liqui Moly 5w 40 - used this in multiple cars with no issues.

Castrol Europeans 0W40 is my typical go-to but Mobil-1 is great, get whichever is cheaper.

I use LiquiMoly currently, I've used Castrol, Mobile 1 and the BMW OEM. They all meet the BMW LL01 spec so not sure how much of a real difference there is.

The LiquiMoly MolyGen I'm currently using has an additive that glows under black light. Very useful in finding oil leaks.

Personally on my half million mile M54 E46 I use Castrol edge high mileage 5W-30 with a ok filter; mobile one or the stp extended life filter as those two typically come with the red o rings which tend to last much longer than the black ones.

I used to run 5w-30 liquimoly, i switched to 5w-40 and all my lifter and cam noise subsided after my second oild change with 5w-40. Id highly reccomend switching to 5w-40 liquimoly.

BMW has been endorsing Castrol since the early 1990's and I have to say that I've never had anything but good results using Castrol. I think it is a great oil and seems to do really well in BMWs.

I have always run Liqui-Moly Longtime High-Tech 5W-30 (blue bottle) in my 2008 NCV3 144" Sprinter in San Diego.

I'm using Castrol GTX 20W50 because it's the only 20W50 that I can easily find locally. I tried Rotella 15W40 but I found that it gave somewhat low oil pressure on my old engine.
