Seeing as how this forum has been kinda slow lately I thought I would stir the pot some. I recently found Silkolene Pro - S. Silkolene Shop Looks to be most promising in 5W40 viscosity. This appears to be another outstanding oil from the Black Forest of Germany. I don't need any oil right away, thanks to a little Lubro Moly and a 32 quart stash of GC green. But that doesn't stop me from doing a little window shopping for my next oil. Anyone have any experience with Silkolene? The customer service guys at Silkolene Shop have been helpful with the requests for specs and questions I have asked them. Has anyone ordered from these guys? Just curious. I've had allot of computer time lately. I broke my ankle last week, had surgery on Monday and have been confined to either lie down or sit in my recliner with my right leg elevated. It leaves me with too much time to search the internet for new and exciting oil.
