Engine oil Castrol or PENNZOIL

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.

Pennzoil Platinum Euro is one of the best oils available as far as NOACK is concerned. It meets most if not all European car manufacturers specs and is the factory fill in Fiat/Alfa engines.

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

Castrol full sinthetic.

Or Motul 7100, even better.

Tie between Royal Purple or Pennzoil, choice usually based on availability or sales. I might slightly favor Pennzoil due to its connection with Shell as I exclusively use Shell 93 fuel for the additives.

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.
