Engine oil Castrol or Shell

For the FA20, I like Rotella T6 Multi Vehicle 5w-30.

Engine runs super smooth with that oil.

I use rotella 5-40 in mine. It's really cheap for a full synthetic and I saw less oil consumption after switching. It's intended for diesel engines but I haven't seen any negative effects after using it for 60k miles. I usually change it around 4k miles.

I use Rotella 10-40w Diesel oil. works great.

I used Shell Rotella T6 5w-40 for a while (not cat AND Sohn installed) and it was fine.

I run Brotella T6 5-40. 22.50 a gallon from amazon. Fantastic Stuff.

Went to the dealer today and got this. 5 QTS CASTROL EDGE PROFESSIONAL 0W20 LONG LIFE IV (RED CAP) 1 VW Oil filter, Volkswagen 04E 115 561 H 1 Drain plug with washer $74.99

If you look at the forums there’s tons of information on this. The rotella T6 5w40 is considered to be the best oil for the EJ hands down.

I run 15W-40 Shell [B]Rotella in my Volvo because it's an old turbo car and the enthusiast community has had success with it.

I ran Castrol 0w-40 euro blend for both my e46s and the stuff was awesome

I did an oil change at 6,300 miles on the factory fill. I sent it in for a UOA through Blackstone labs, but I'm not sure how to attach it here. The TBN showed some life still left in the oil, they suggested trying 8,000 miles next.
