Blotter Test

['00obw]

Would be nice if all those who do used oil analysis would also perform a blotter test and post pics with their used oil analysis. Might help to learn to read a blotter test. Just an idea.

Where is a good place to buy blotter paper? I tried the one phone number and got no answer. I've used index cards in the past, but even oil from a bad UOA with no TBN left didn't show much on the cards

Thanks
