Engine oil Mobil or Castrol

I run Castrol Edge in my VDub. It's the European blend that is approved by VW as shown on the back of the jug.

I use Castrol R, smells great and reminds me of riding 2 stroke bikes from my younger days.

I run Mobil 1 in my bikes.

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)

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 mobile one 0w40 but burned oil so I filled it up again idk might be cause of the heat or of course the motor which would be normal, but I usually aim at chaning the oil every 8k or half miles on my 2.0t TFSI engine and now I'm using 5w40 motul for my up coming oil change
