I agree on reps when asking about their products, but my question was more about oil age in general, im sure if i called back the next day and spoke with a different rep the answer would be different.

I also go by what many life long mechanics & racers I know have said on oil topics like this or weights or zinc etc, as well as my personal experience which seems to be working very good over a few decades with classic pontiacs and daily drivers of different makes.

A UOA of low mile oil but at 1 year old would be very interesting. I understand not draining it but really too many variables with that depending on how/where it was stored & how often it was driven to full temp during that time. In my cars, the low mile oil that is 1 year or older does get started & used, full temp drives that burn off any moisture, in winter they sit for a few months without any short starts that introduce lots of moisture. So the engine could be started & fully warmed before the sample is taken since most cars are used during the 1 year or more age of the oil. Im sure 1 year will have different results than 2 or 3 years.

Whats the current price for a test at blackstone?
