Here is my latest Blackstone, after 6k on Mobil1 0w40 and bmw 5w30 syn oil, and a new air filter, for those interested in what a Blackstone will tell you. This fill also had 300ml of Liqui Moly oil additive, which appears to increase the moly and explains the additive level. I ran a 500ml can of the Liqui Moly cleaner through before this change, too. Note the drop in silica, probably helped by a clean air filter.

The current fill is Pennzoil Ultra 5w30, a high detergent syn oil. I will add another 300ml can of Liqui Moly to it and go at least 6,000 miles before the next change.

Also - If they check out, I'm about to buy a set of 18" 209 style wheels [5 spoke] off a 2013 E70, never used [pix attached]. They have Bridgestone all season RFTs mounted. The deal is good enough that I'll try the tires and sell them to one of the many used tire guys around ATL and mount real summer tires on these rims if I can't stand the RFT ride. I was looking for staggered 19 or 20" wheels, which would look great, but their relatively high price and tire costs convinced me that was money better spent elsewhere. I have Conti DWS all seasons mounted on 131 stye 18" wheels, great tires, but the summer heat is tough on them and increases road noise significantly. I'd rather save them for Nov-March GA use, and eventually get to high performance summer tires on the 209s. I'm thinking either General Grabbers, Goodyear Eagles, or the Bridgestone Dueler HP (summer, not RFT) for summer use.
