There are a number of options. I use the Caterpillar S.O.S. program. Amsoil
and Blackstone labs are two the popular choices. Just google oil analysis.
Basically you buy a kit and some method of drawing a sample. You don't want
to take a sample from the drain plug as you will always pick up contaminates
and may also get bad readings from the concentration of stuff at the bottom.
The most common choice is a vacuum pump and sample tubs drawing oil from the
dipstick tube. The kit will include a mailing container and it usually
includes postage. Hey mail or e-mail or post the results on a site you log
into. The kits often get less expensive if you buy in quantity. Figure $13
to $20 per test.

Subject: Oil Analysis, where, how?

Hi lister's,

        How would I go about getting a oil and or coolant analysis for my
Bus?

        I have only heard of doing this from this list and it is a
completely new idea.  Thanks.

Also, I'm having all fluids changed at the moment and have time to ask for
samples if I hurry.  What do I need and which fluids can be tested?
