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?

The lifelong mechanic and engine builder who taught me most of what I know about engines would tell you to change the damn oil! Of course, his engines only won two USAC National Sprint Car Championships; the other lifelong mechanic and engine builder who taught me much about building modern competition engines would tell you to change the damn oil. He only won an NHRA World Championship. What would they know?
