No, not an oil debating thread, but where can I buy Castrol GP (Castrol ActEvo GP 4T) for my 1200GSA at a realistic price? So far, I can only find it at BMW Dealers for about 9 pounds a litre. I e-mailed Castrol but got no response.
Someone must retail 4L without breaking the bank or does everyone run standard 10-40 GTX?
Is there an alternative that BMW won't say affects the warranty?
