A couple of weeks ago, perhaps even 3, I requested the Blackstone oil test kit but so far, nada. I'm changing oil this weekend (replacing M1 5-30 with GC 0-30) and this would be a good time for them to send the kit. Even if I could collect the sample oil in an acceptable method and container, I'm not sure that I want to give them my business if they can't send the kit as promised. This would be my first UOA and we don't have many for 4.0 SOHC Explorers with this oil. Would be informative and it still could be. Is anyone at Blackstone home?
