Years ago, I bought a case of Castrol 20-50 (still in cardboard "cans") at an auto flea market. I had planned to use it in an old VW Beetle I had, but forgot all about it. Having read through a couple of threads on old unused oil, I'm wondering if I could use it in my '63 Buick 215 V8.
I'd like to send a sample in for analysis to see if, and how, it may have deteriorated. Obviously, UOA looking for products of combustion and motor wear isn't an issue. What sort of test should I request? Since the test is likely much simpler and I am not sampling over time, I am guessing the cheapest lab around could do the job. Any recommendations on economical labs?
Thanks in advance.
