Paul - The site I've linked in the original post is one for "interested parties" to fund small ventures of various types. The first batch is supposed to ship this fall.

Sammy and others- they used test results from Blackstone analysis results as well as an $1,200 SKF Oilcheck TMEH-1 professional oil tester to calibrate their results. This product basically gives a scale of 1-10 (green, yellow and red LEDs) to indicate the oil quality based on several parameters.

To me, I'm not sure it's worth the $30. I'd rather change my oil (too) frequently than postpone an oil change based on a test result from this. For someone in the market for an oil tester and the $1200 unit is being considered, this $30 alternative could save some dough.
