Does this include shipping of the sample container to you? Do you have to buy into some Amsoil membership to get this price?
Wearcheck charges $35 for their MOB2 analysis which includes TBN and TAN, but there is also an additional charge to ship the sample kit to you, which was $11 in my case. They overnighted it by UPS, although I did not ask for it. Maybe if I had asked for some slower shipping method, it woukd have been cheaper.
You do have to be a member ($16 per year), but the cost difference on one UOA will essentially pay for it and if you buy more than one, you are ahead. There are shipping costs too, but I buy in bulk or pick up at the warehouse to defray, with that said, I see shipping costs as moot because most companies charge for it anyway.
I have tried 3 UOA companies--Blackstone (50+), Horizon/Polaris (20+), and Wearcheck (4). I prefer Horizon/Polaris due to overall quality, consistency, all applicable ASTM/ISO processes/certifications, cost, and convenience (there is a lab in Houston).
