BMW 5 Series E60 - VISCOL - RoyD
I have seen in a local discount store a brand of oil called VISCOL. The 5W-30 full synthetic claims to meet the BMW LL04 specification. I was wondering if this oil is suitable for my 2008 BMW 520D. It is selling at a third or less of mainstream brands. Thanks.

It will be absolutely spot on. Viscol are part of the company that makes Rock oil, a very well known bike brand.
