If your timelines are correct then I'm sure lots of the oil I still have in the garage is SJ. I thought oils were supposed to be getting better as time went on. Less anti wear agents and detergents seems just the opposite to me but like I said in a previous post I don't know much about motor oils. I'll be 61 in Nov. and I'm pretty sure I have enough oil in my garage to last me the rest of my life. Over the past few years when I've caught good sales on it I've bought some oil to replace some of what I've used over the past 20-25 years just in case I live long enough to use it. I was in the garage yesterday and noticed I have enough Citgo Supergard to do about 20 oil changes in the Versa. Rather than change brands all the time if I have lots of one brand I pick a car to use it in until it's all used up then change brands in that car if necessary. My '97 Escort is using Exxon Superflo that I had in the garage when I bought the car in Feb. 1998 and is all I've used in it since I drained the factory fill oil. The Escort doesn't get driven a lot it currently has 41K original miles. I've got about (6) 5 qt. jugs of Pennzoil Platinum that I bought years ago when they ran it on sale with a rebate, the final cost was $5. per jug. I'm still using oil in my mom's Grand Marquis that dad had in his garage when he died in 2010. I think there's enough to do about 1 or 2 more changes and is soon due a change.
