Long story, but the gist of it is that my Dad passed away 2 years ago and recently while cleaning out one of the storage buildings I found 2 cases of QS conventional 10w-30. I have no idea how old it is, he had a habit of finding oil on sale and buying every bit a store had in stock. This oil would have been intended for my 1988 Monte Carlo Super Sport which he loved to drive and would "borrow" from time to time. Every time he would "borrow" it the car came back with a fresh oil change and wash/wax. The old man loved that car.
Anyway, I have looked over the cases and the individual bottles and can find no date stamp, at least none that are obvious to me. So, is there an easy way to tell how old this oil is? What is the shelf life on unopened oil? So many questions.... I also found a stash of 10 AC Delco oil and 10 AC Delco air filters for the car. There were a few Wix oil filters mixed in, but the vast majority were AC Delco. Dad sure loaded up when he found a deal.
Also, I have been buying Valvoline conventional 10w-30 and usin git in the SS for the last 5 years or so and am just wondering what the forums thoughts are on that oil vs the QS. My Dad was a QS man since the 1950's and finding his stash of oil for my car made me wonder about QS v Valvoline for that engine.
Thanks for you thoughts!!
