Engine oil Castrol or RED LINE

I use 5w40 Castro’s European blend in my 06 e60 530xi and it seems like it does the job.

I used Castrol Edge 5w40 last oil change and the engine feels smooth and burns little to no oil.

I used Castrol GTX 10W-40 High mileage and never had issues.

Pennzoil Ultra Platinum or Castrol Edge are probably the best all round oils.

I put 5w40 in mine, that's what is recommended for mk6 at all temps. Summer or winter months. I use Castrol Edge Full Synthetic high mileage, works a charm.

The 0-20 Castrol VW Spec oil I buy from my dealer is cheaper than any 0-20 from Walmart or auto parts stores. My 2019 GSW has 16,000 miles and uses next to no oil between changes. I have averaged over 40 mpg for the 16K miles.

When it comes to oil I have one thing to say. Use Valvoline or Castrol 3000 for conventional 5 to 7000 for synthetic,. If you do this and take good care of your vehicle your car will go 200,000 to 300,000 miles.

I happen to use Castrol in all my gasoline powered vehicles and have had no oil related issues. Given that VW promoted Castrol and, more importantly, that I prefer Castrol in general, I’m staying with Castrol when I can... I've had no oil loss in the Tig with Castrol and see no reason to switch to a different brand just because some MBAhole behind a desk made a profit driven decision to switch suppliers.

I use 15w40 GTX Diesel Castrol oil, it works.

As much as I love to use Mobil One, I am going to stick with Castrol because VW dealership won't give me any credit for the Castrol in exchange for the Mobil one.
