Was at Wallyworld adding to my shrine of GC, when I looked over and noticed that the Mobil 1, which used to be somewhere in the upper $7 range had dropped to being actually lower then the $6.66 price I pay for the GC, I think was around $6.50 or so. I believe it was Mobil 1 supersyn 5W30, is this stuff any good, or is it the Mobil 1 that many people say to stay away from. Anyways, I have enough GC for 4 oil changes now, so not in a hurry, but if this is the good stuff might be switching to Mobil 1 after that. (and no it won't take me very long to run thru 4 changes of oil)
