I found a pretty good deal on some Castrol GTX, 12 dollars for a 5quart jug, but the oil jug is slightly older than the most current one, it has up to GL-4 which started in 2004 on the back, but GL-5 is out. any way to tell how old it is by the jug markings? is it still good to use??
here's pictures of the labels

And I keep adding a little MMO to my oil sump every 30 miles, because it seems to be burning off at a high rate, if I don't add more and just let it go the oil doesn't drop at any notable rate, but if I add 1/4 a quart of MMO and drive 20 or so miles check again, its back to the mark before I put it in?? so that leads me to the question does MMO burn off??
