Engine oil Castrol or Shell

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'm a big Brotella Bro. I've used Rotella T6 in my WRXs, Miata, sport bikes, and dirt bike.

I suggest running Shell t6 5w40

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

Rotella 15-40. FTW

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

I run this one in our 04 BEW TDI. No issues what so ever!

Rotella T-Syn is a great oil but for our turbos...i wouldn't recommend it since if any oil gets burnt or makes it way through the rings...the higher amount of ZDDP (zinc) found in the Shell Rotella Synthetic oil will be harmful to your catalytic converter which may cause a failure.
