Engine oil LIQUI MOLY or Castrol

Castrol full sinthetic.

Or Motul 7100, even better.

I use Castrol on my z4. Works like a charm

Castro Synth. is all i ever used in my BMW 60,000miles runs perfect change every 7,000 miles

(5w-40)

Liquimoly is by far a better 5w40 to put in a bmw.

After some research I heard people use 5w40 to quiet the motor down and lubricate the lifters better for high mileage engines. picked up some castrol edge 5w-40 and it runs buttery smooth, noticeably quieter and another big thing is oil consumption drops A LOT due to the oil being thicker and harder to burn or leak. I used to need maybe a quart a month now Ik down to half a quart a month.

I use this Castrol Edge 5w40 for 5 years already in my e46’s m54b30. No issues. Trying to stick to 10k km intervals.

In my e39 M54B30 473k km I am dumping Castrol Magnatec 5w-40.

Nothing to complain.

I used OEM, Motul, and LiquiMoly oil. The only one that seemed to do anything with oil consumption was the LiquiMoly. I changed the oil every 5k miles and I had similar experiences as you until I did the LiquiMoly. Completely anecdotal, but I’m a believer. Been using it ever since.

I use castrol 5w-40 Euro on my 2006 Revup. Good oil pressure on hot SoCal days and burns less oil.

I personally used to run mobil 1 0w-40. as you said its super thin and seemed to just barely get the job done. Recently switched to castrol SLX 5w-30 and I am decently pleased with the first two changes.
