I used Blackstone Labs for an oil sample a couple of weeks ago. They are a mail order type outfit that sends out a free sample test kit to try them out. They did a good job for me.



Blackstone Labs



They're not in CO, but... .
 
I have been using Blackstone too, no complaints and tell them you are a TDR member and they will take a buck or two off the regular price.

oil sample

check with any cat garage. i use them in my shop they sell a pre-postage kit for about 8 bucks thats kit sample and all in one price.

just drop it in your own mail box usually get results in about two weeks.
 
The only reason I can figure a lot of folks use Blackstone is because they come up first in an internet search because of their order in the alphabet.

They charge around $20 for a test you can get done elsewhere for under $10. I pay $9 at the local Cummins dealer, sometimes they have a special for $6.
