But that's Mobil 1 5W50 FS. Castrol 5W50 maybe different. Please let us know your experience with oil consumption using the Castrol 5W50. BE Bearings recommends 10W60 after using their increased clearance bearing shells.

I've never had noticeable oil consumption using any oil, including the 5W50s. I've been running BE bearings since I got the engine.

As soon as I got back out on track the car felt much more responsive, especially in the upper RPM range. Ever since that day, I've stuck with 5W-50 or 15W-50, regardless of brand, just not Liqui Moly.

Exactly my experience. It just feels so much happier with 300V 5W50.
