This seems to be one of the cheapest prices currently for 5L of Castrol Edge LL 5W-30 at $56.70 from $80.99. It is 30% off the original price.
Not like A3 version of this oil, the LongLife (LL) version rarly has discount, like seem from last year. I have not seen it cheaper anywhere else currently. Autobarn has it for $64.99.
This oil is mainly originally used for German made Diesel car with DPF, e.g. Audiļ¼ BMW & etc.. It is approved by vehicle manufacturers/graded as follows:
ACEA C3
Mercedes-Benz MB-Approval 229.31 / 229.51
Porsche C30
Volkswagen Auto Group (VAG) VW 504 00 / 507 00

Annoying how expensive this stuff is. My Skoda is chewing through the oil at the moment too. Unknown why.
