oil question

I run 5w30 mobil 1 syn. oil. If I can not find a jug I get 10w30 mobil 1 syn. I dont think its that big of a deal...both are like water in that brand/weight and will give good protection. The filter is probably more important than a debate over 5w or 10w. Mobil 1 filter and motorcraft is all I would run.

Side note. The only thing I buy (wife buys other things of course) from Wal-Mart is the mobil 1 syn. oil. It is like $22 for a 5qt jug that is perfect for the 5.0 mustang. It may be more now with all the price increases but it should still be comparable in cheapness. Keep in mind this is oil that can be found for at least $5-7 a qt or more that is $25-35 if bought by the qt.
