Engine oil Castrol or Motorex

I used to use German Castrol 0w20 in my Volvo and it was green too.

I use 10w40 full synthetic oil, and only the best quality stuff. Valvoline, Castrol, Pennsoil, Mobil1, Idemitsu end the like. Before my rebuild, I was using Idemitsu Rotary blend but switched to Castrol GTX. The GTX semi synthetic blend had a slightly lower oil temp and lasted longer per oil change than the Idemitsu, indicating that it was lubricating better.

I think you will find out Castrol EDGE® Euro Car 5W-40 A3/B4 Full Synthetic is a better all around oil then and oil I’ve owned Volkswagen all my life and that’s all I’ve ever run in my vehicles never had a problem and if you want to run the 10,000 miles between oil changes this oil will handle it

I've always run Castrol with no issues. The biggest thing is to make sure that whatever oil you use meets the spec required by your engine.

I use Castrol GTX full-synthetic 10W-40, as I live in Texas where the average temperature is hotter than the rest of the US and oil weather varies drastically. During the summer, I've considered bumping up to 15w-40 due to how hot my startup temps are on a "cold start".

I put castrol, engine sounds better to my liking, anyway make sure to check the user manual for the EXACT OIL CAPACITY AND TYPE

I’ve always used castrol edge on my old cars, and the oil comes out cleaner every time I do an oil change. That’s been my experience

High mileage oils like Castrol edge have more detergents than other oils, not a marketing gimmick.

Change my e90 n52 every 15k, castrol titanium 10w-40. blackstone reports confirm the oil still meets spec with plenty of detergents left. Showing no signs of wear at 170k.

I was using the OEM Castrol 5w40 and recently switched to Castrol European Formula 0w40. I found that I had the oil level drop a bit (oil burn perhaps) with the latter. For the current change I went back to OE Castrol and will see if things go back to no level drop.
