Stopped in at my local 'zone today to see what oil was on sale, and was looking at their Pennzoil conventional selection, and 6 old looking bottles with red caps caught my eye. It was Pennzoil 10w-30, it had SJ on the donut on the back and I believe was GF2. It also had a short blurb on the back about their additive pack, but I forget what they were calling it. I don't know what dark corner they dug this stuff out of, but how old is it guys?
