Engine oil Castrol or OEM Volkswagen

5W40 Castrol Euro. I get less oil consumption than 5w-30 and it seems to run a bit more smoothly.

Castrol Edge 'Euro Car' 5W-40

Used to get a big white plume on cold starts but no more. Still burn a lot, but not as much

Best oil I've used

Yes you can I’ve been using 10w40 castrol ever since I got it and I’ve been fine

I use Redline but for a million years I used Mobil 1 car oil. Before that we used Castrol 20/50 petroleum oil

I always ran castrol gold motorcycle 20w50 on my Harley's.

I always go for Castrol Edge. Always have, always will

On my ( 2006 Mazda 3s 2.3l auto sedan 350k miles ) I don't burn a single drop of oil and the car runs great even the transmission and I've been sticking to 5W20 Castrol edge extended performance all year

My car is at \~7600 miles. I changed the oil at 500, 5000 and then I'll change it again at 10,000. I used Castrol Edge 5w30 for the first two and I'll use it for the third oil change as well. I'm going to send a sample of the oil at the 10k change to Blackstone Labs to see how the Castrol is doing.

Castrol makes a Edge Euro 5w-30 and 5w-40 that is LL-01 and ACEA A3/B4, it's not going to meet the later LL requirements because it's higher viscosity and not as fuel conserving, also not low SAPS so potentially it could contribute to more intake valve buildup

I hated the castrol, I could tell the engine was louder with it compared to Pennzoil.
