Does mobil 1 make 5w 20 weight oil? If so where can you find it?

Ok, I am sorry I was mistaken then.
I was persuaded by the earlier talk of the 5w30 being better, but after talking to one of the guys at ford it seems that the reason they want to use 5w20 is because there is less clearance between the pistons and the block. The larger weight would not lubricate as well because the pistons do not have as much clearance. I don't know how much the guy knew, but it seemed to make sense.
