Which lab should I use for VOAs?

[Carlostrece]

I'm considering sending in some HM FS oils for lab testing VOAs. Which lab(s) do you recommend?

I'd like the VOAs to show, oxidation, TBN, and accurate cSt @ 100C. It would be a nice bonus if it also shows cSt @ 40C.

Oil Analyzers is a popular recommendation here. It's really Polaris Laboratory but you can get them for less money through Amsoil. You might want to look at previous posts regarding labs as well since this is a common question.

I was originally thinking Oil Analyzers or Speed Diagnostics. So far it's unanimous for Oil Analyzers. Thanks for your input @fantastic and @Glenda W.

The oil was recently changed in all vehicles that I'm responsible for. The next time the cars are due for oil changes, I will buy new oil and contact @Pablo to place an order to do some VOAs with Oil Analyzers.

OA is good, but my personal favorite now is WearCheck in NC. Every single sample I’ve sent in has had a turnaround of 2 days, they use FTIR and GC for fuel, and have oxidation and nitration included in the basic OA package.
