Polaris Labs--home based in Indianapolis but they have several labs around the countryside. Used to be about $25 a sample. They send you the jars, you put in the oil and send back, get the report via e-mail within a week.

Re: Engine Oil Test Kit
We have been using any Local Cat Dealers to get engine oil checked for years ! I'm sure there's other places to get it checked, but going to the local Cat dealer saves me time and a bunch of phone time ! Cus I know Cat will check it and I don't need to look around ! I guess I'm just simple and lazy LOL
