It took me 3 trips to 3 different super walmarts to finally score some mobil1 0w-40 in arlington, texas. On my third stop, this automotive clerk told me that they will discontinue this oil because not enough people are buying it. They'd rather buy the 5w or the 10w's. Have anyone else heard or seen about this? sorry if i reposted same topic... im a little depressed that my GC 0w-30 at autozone and maybe my mobil1 0w-40 will be gone at walmart.. i dont know if autozone around my area still carries the m1 0w-40. i have to check sometime later.
