I like Blackstone a lot. I do get the TBN and TAN only because I go longer between oil changes. Street use only between 8 and 10k and Blackstone has always said I could go more. At only 5 to 6k even with a couple driving events youre not likely to wear the oil out. On the other hand it's only 10 bucks.
A curious thought about the slightly high silicon: factory air filter or one of the 'high performance' so called oiled filters?
