I prefer VOA's because I am most interested in the additive make up of the oil.

Please define VOA’s and UOA’s for the newbies, and you’ll get more replies.

Generally VOAs just to know what I might be pouring in, but a UOA of the same oil/engine that I have would be even more interesting to me than a VOA

But......
VOA's do not tell the story... it's just an elemental analysis.
They don't tell you what type of chemical formulation exists... just "elements"

"Oh, look at all the zinc!"
You don't know if it's ZDDP or ground up pennies
(or the zinc gear case of the oil transfer pump that fills the jugs is wearing out)

VOA's tell nothing of which basestocks are used in the make-up.

UOA's at least tell you how well an engine is wearing on a certain oil,
or if there are issues from other contaminants.

Really good VOAs, like those found on the PQIA site do give a good indication of the quality of the basestock blend used since they include MRV and NOACK numbers.
UOAs are mainly interesting as an indication of shearing, TBN retention and oxidation, all of which will depend upon the engine in which the oil was run and for how long as well as how the vehicle was used.
They're also interesting as a gauge of just how badly certain engines fuel dilute the oil.

I like both. And what's become immensely frustrating is searching uoa's and voa's only to find the host is no longer active.

UOA's - between the manufacturers data sheets and PQIA I can get a good idea of where my base is. You arent ever going to get the "magic sauce" exactly.

Unless Im concerned about contamination I don't bother with VOA's.

Photo buckets revenue model killed a bunch of available info for everyone.
Free service with ever increasing bandwidth on their side and no revenue didnt work for them - no surprise.

Used to be much easier to search for UOA's on your particular platform and see what you were working with.

No you get the "photo offline" gif.
