The non-LL version often goes on sale, but this one seems to do so much less often. My car has a 12 month service interval according to the factory, so I do my own services on the 6 month mark between the factory services - not a bad idea to stock up a bit so you've always got oil on hand.
Castrol EDGE 5W-30 LL meets the following approvals:
VW 504.00
VW 507.00
BMW-Longlife 04
MB-Approval 229.31/ 229.51
Porsche C30
The LL stands for Long Life to enable extended interval servicing yet you service your car earlier and pay extra for LL?
I'm confused.
