I know this has been talked to death but a quick read of this may be helpful to some. In particular see the article stating that Blackstone now PAYS the POSTAGE.

Ive used Blackstone for years. Just got back the analysis on my generator, which was way over the 100hrs change interval specified by powertech, but far below what most diesel generators run. I was worried the fuel system may be leaking fuel into the oil because it was a little over the full mark after 280 engine hours, but the analysis came back perfectly fine and I could probably go 500 hours on this current oil change in the generator.
