			Did anyone notice that the only xW-50 weight oil (on the approved list) was Mobil 1?  Interesting.  I wonder why.
 I can't seem to find Mobil 1 10w-40 in stores.  Anyone know where I can get it?  Wal Mart had Mobil 1, 5 quart bottles of 10w-30 and 0(I think)w-50 for $20.  Can I use one of these safely?
