For fellow F-series BMW riders, RuralCo have a cracking deal on Castrol GPS 10W40 (BMWs recommended oil for the 800 twins) at $56 for 4L, including delivery.
Best other price I could find for such a fine vintage of Dino juice was well over $100

They also have Castrol Power 1 Racing, for those that want fully-synthetic at $80-odd.
They seem to have great pricing on all Castrol products, including chain lubes, etc.
