Hello All - I decided to change the oil, so I went to all the usual places, Auto Zone, Advance Auto, Wal-Mart and finally NAPA where they had 6 quarts of VR1 10W30, I quickly grabbed all 6, while I was checking out I noticed there wasn't the usual yellow sticker touting the zddp in the oil, I thought maybe the sticker was only on the newer bottles, so off I went with visions of floor jacks, dirty hands, and recycled oil dancing through my head. I got to the man cave, unloaded the oil and just happened to look on the back. Under what looked to be a serial number was the number 1987 stamped. Are you kidding me, is that number what I think it is? I know Dino oil has been in the ground for like a billion years, would you put 20 year old oil in YOUR car? Thanks for your input.
