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?

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?

And yes, oil for aircraft piston engines, diesel engines and classic automotive engine allegedly have these “acid neutralizing compounds” in them, but in my 6,000 engines of experience I have seen few engines that were stored long term that DIDN’T have varying degrees of acid damage.

Thats great you had those experiences, but again way too many variables to say that happens to everyone elses engines. You said in those situations the engines werent warmed up long enough to get rid of moisture... that doesnt apply to my examples & experiences or most others that know how to store an engine properly.

So just to clarify this, when I talk about oil changes at 1 year or longer I mean for engines that are stored properly or get driven regularly/occasionally to fully warm up the engine/oil and on a healthy engine... other situations with other types of engines like air craft or high mile dirty engines or short starts some do in the winter to "lubricate the seals" that introduces lots of moisture dont apply here.

That UOA looks like new yet. HR1 is suppose to be an 8000 mile conventional oil, it has a ton of detergent in it.
